DETAILED DESCRIPTION OF THE INVENTION
Turning now to the drawings, many embodiments a number of different seating systems that improve the overall function and design of the vehicle seating. For example, many embodiments include a passenger seat with a base seat or platform that has a back seating support that is connected to the base seat. The back support can have multiple positions and many embodiments may include a secondary seat base that is connected to the back support and can fold down to form the base of a rear facing seat. In conjunction with the base for the rear facing seat, the back rest can be rotated such that it serves as a back support for the rear facing seat. Thus, the passenger seat can have a front facing and a rear facing configuration without significant movement or adjustment to the support of the overall seat. In many embodiments, the passenger seats may include a number of different sensors and alternative systems that can detect the occupancy of a seat such a number of different safety and alert systems can be activated and/or engaged. In some embodiments, the seating configurations may include a side facing seat. The side facing seat, in accordance with numerous embodiments can be engaged or disengaged by folding and/or rotating into an open position for seating. Additionally, many embodiments include systems and methods designed to prevent the vehicle from moving when certain conditions are met.
Traditional vehicles, to include some electric vehicles tend to use a more traditional style seating arrangement and seating systems that are designed to provide comfort and safety to the vehicle occupants. For example, traditional vehicles tend to follow a front and rear vehicle layout with a front and rear passenger space that is often confined by the more traditional front engine compartment and a rear trunk space. Many modern vehicles also have a variety of safety features including passenger airbags and safety restraints. Additionally, some vehicles include a number of other safety mechanisms and methods that can control or prevent the movement of a vehicle in the event of an imminent collision.
As the development of vehicles have evolved, with the inclusion of electric vehicles, so have the various types of seats and seating arrangements within vehicles. For example, some seating designs that have allowed for adjustability have included electronic motors or actuators that can adjust a number of different positions of a seat such as the lumbar support, the position of the seat with respect to the steering wheel or steering mechanism as well as side to side and tilt adjustments. All of such adjustments can be used to improve the overall comfort of the passenger and/or driver of the vehicle. Additionally, with the evolution of vehicles have come different designs in how seats can be positioned within a vehicle. For example, FIG. 1 illustrates various designs of seats within a vehicle based on known art. Some seats may be configured to swivel 102 in their entirety where the whole portion of the chair or seat rotates around to be mostly rear facing. Other seat designs have shown to have a moveable back rest 104 that pivots from one side of the seat 106 to the next at a central pivot point 108, offering alternative seating positions. Some vehicle seating designs have offered fold down seating pieces 109 that are affixed to a rigid bulkhead element 110 where the bulk head element 110 can serve as a back rest as well as a support. Despite the different designs of various manufactures, many still fail to take advantage of the unique features that can be afforded through an electric vehicle platform. Furthermore, many such prior art seating configurations tend to be bulky and require a lot of room to adjust. Others, while simple, tend to be impractical for full scale implementation. Still some designs, such as the bulk head support can be uncomfortable and offer little to no adjustability to improve comfort. In contrast, many embodiments described herein offer a low mass, easily adjustable, space saving configuration that can improve the ability for occupants to occupy a rear facing position within a vehicle without compromising the spatial integrity of the vehicle. Moreover, many embodiments offer modularity such that the seating configuration within a vehicle can have a number of different layouts and still include all of the fundamental and necessary safety features of a modern vehicle.
Turning now to the figures many vehicles 200 as illustrated in FIGS. 2A and 2B may be adaptable to a variety of different seating configurations such that the interior of the vehicle cabin can be open and spacious. For example, FIG. 3 illustrates an interior view of a vehicle 300 with what may appear to be a traditional front 302 and rear 304 seating arrangement that is positioned behind a steering mechanism 306. However, some embodiments may incorporate a non-traditional side facing seat 308. Although a more traditional seating configuration may be illustrated, many embodiments can take advantage of an electric vehicle platform 310 that does not have a traditional front engine compartment or the traditional trunk space in the rear. Accordingly, many embodiments can position the front seats 302 more forward in the vehicle and thus provide a more open rear portion for the rear seats 304 and the side facing seat 308. Additionally, many embodiments can have front seats 302 with alternative configurations that can further open the cabin and seating configuration.
The various embodiments described herein illustrate a vehicle seating arrangement that improve the overall comfort and modularity of vehicle seating layouts. While the current disclosure may divide many of the functional and structural elements of seating systems into individual sections for clarity, it will be understood that vehicle seating arrangement and individual seating systems, according to embodiments may combine, include or omit any of the described elements as desired by a specific vehicle design.
Embodiments of Seats
FIGS. 4A through 4H, for example, illustrates passenger seats 402 for a vehicle that can be configured with multiple seating positions as well as contain multiple integrated safety system sensors and/or switches that can be activated in response to the various seating positions. FIGS. 4A through 4C illustrate side and front views of a passenger seat 400 with a base seating element 402 and a back rest 404 in accordance with many embodiments. Some embodiments of a vehicle seat may also contain an upright head rest 406. Although such basic seating components are relatively known in the art, many embodiments of a vehicle seat may also contain a connected secondary seating base 408 that is connected to the overall seat 400. In accordance with some embodiments, the vehicle seat may also contain one or more occupant position sensors 410 that can be located within the primary or secondary or both seat bases of the overall seat 400. An occupant sensor can be used in a number of different ways to help ensure the ultimate safety of the vehicle and occupants is maintained. This can be done by preventing use of the secondary seat base 408 when an occupant positioned in or using the primary seat base 402. Additionally, the occupant sensor in the secondary seat base 408 can be used to prevent movement of the vehicle when the secondary seat base 408 is in use. Many embodiments of a seat 400 may also include more traditional seating elements such as lumbar support systems 412, safety restraint latches 414 as wells as seat adjustment mechanism 416. The seat adjustment mechanisms can be used to adjust the seat in the traditional sense of up, down, forward, and backward as well as tilt. In many embodiments seat adjustment mechanisms can also be adapted to control the movement of the seat back 404 between the front and rear facing configurations.
Turning now to FIGS. 4D through 4G various seating configurations of a seat 400 can be illustrated. For example. FIG. 4D illustrates a seat 400 in a front facing configuration (FIG. 4D), where the back support 404 is positioned in a more upright position such that an occupant may sit on the primary seating element 402 while the secondary seating element 408 is in an upright position and is configured substantially parallel with the back rest 404. In numerous embodiments, the secondary seat element 408 can be moved into an engaged position, as illustrated in FIG. 4E. The secondary seat element 408 can be moved into position by a rotational movement in some embodiments, while other embodiments may use a sliding mechanism to move the secondary seat element into a seating position. In addition to the movement of the secondary seating element 408, many embodiments may incorporate the movement of the back rest 404. The back rest 404 can be moved or rotated towards the front of the seat 400 such that it can also serve as a back rest for an occupant seated in the secondary seating element. Thus, the seat can have two different configurations in which the back rest serves both front and rear facing positions. In accordance with many embodiments, the back rest may be configured with cushion elements on both the front 418 and the rear 420 portions of the back rest 404. In accordance with some embodiments, the seat 400 may be configured with one or more arm rests 422 that can be positioned for the front facing position (FIG. 4F) or the rear facing (FIG. 4G). As can be appreciated the arm rest 422 can rotate and be secured in a number of different positions such that it can serve as an arm rest for a forward and a rearward facing configuration of the seat 400. It can also be appreciated that the seat 400 may be configured with more than one arm rest and that the arm rest 422 can be removed as needed or desired. Traditional vehicles place the more external driver and passenger arm rests within the door panel. This tends to place the occupant in close contact with the actual door panel which could pose potential risk to the occupant in the event of a side impact. Accordingly, many embodiments that may incorporate an arm rest configure the arm rest to be connected to the seating element in some fashion. This can improve the overall safety of the occupant by positioning them further from the door in the event of a side impact.
Seats, as described above can take on any number of configurations and may be adapted for a driver or passenger position within a vehicle. Additionally, in some embodiments the secondary seat element as described above can take on any number of configurations. For example, FIGS. 5A through 5C illustrate a vehicle seat 500 with a base frame unit 502 that has a seat portion 504 and a back rest portion 506. The base frame 502 can have a number of different attachment points 508 that can be used to connect the base frame 502 to a support structure 510 or to the rear seating element 512.
The rear seating element 512, in accordance with various embodiments, can be connected to the base frame 502 with a hinge element 514. The hinge element 514 can allow the rear seating element 512 move from an upright position (FIG. 5B) to a seating position. Moreover, the hinge element can take on any number of forms. For example, as illustrated in FIGS. 5B and 5C, the hinge element 514 can be laterally attached to the base frame 502. In numerous embodiments, the hinge element 514 may be a horizontal based hinge that is attached laterally across the width of the base frame 502. Although a specific hinge element is illustrated, it can be appreciated that any number of hinges can be used such that the rear seating element 512 can be moved from one position to another.
In addition to the various configurations of hinged elements or moveable connections between the base frame 502 and the rear seating element 512, some embodiments of a vehicle seat may incorporate a rear seating element 512 with an integrated arm rest 516. The integrated arm rest 516 can be advantageous in that only a single element is needed for the seat 500 when it is in either the front or rear facing positions. It can be appreciated that the rear seating element 512 and integrated seating element 516 can take on any number of different configurations and or designs that may be suitable for the various vehicle configurations. Furthermore, it can be appreciated that the hinged element 514 can allow for the easy removal of the rear seating element 512 such that it can be repaired and/or replaced with a new or updated design or a repaired element. Such modularity can be advantageous form a maintenance standpoint as well as a cost savings for potential users. Rather than have to repair or replace the entire seat 500 individual elements such as the rear seating element 412 and the back rest 506 can be removed and replaced as needed, thus minimizing the overall cost of repairs.
As previously discussed, vehicle seating and seating elements can take on a number of different configurations. For example, FIGS. 6A and 6B illustrate alternative seating configurations for a front eat with rear facing seat from those previously illustrated. FIGS. 6A and 68 illustrate a vehicle seat 600 where two seat elements 602 that are interconnected on a single support structure 604. Similar to various single seat embodiments, dual seat embodiments as illustrated in FIGS. 6A and 6B may be configured with seat back elements 606 that can rotate between a front and a rear facing position. It can be appreciated that the seat back 606 can take on any number of designs such as an arched type design as illustrated in FIGS. 6A and 6B. The arched shape of a seat back 606 can be advantageous for many embodiments because a convex side 608 can serve as the back support for the rear facing position. As can be illustrated the seat back 606 can be rotated such that it leans over a primary seating element 609 when in a rear facing position. Alternatively, the concave side 610 can serve as an appropriate back support for a front facing position. Although not illustrated in FIGS. 6A and 6B it can be appreciated that the seat back element 606 can be rotated such that the convex side is leaning towards the rear of the seat 600 such that it might provide an adequate back support for an occupant in the primary seating element.
Additionally, as with many embodiments described herein, the rear seating element 612 can be positioned in a seating position and/or a storage position. Illustrated in FIGS. 6A and 6B the rear seating element 612 is positioned in an open configuration that would be suitable to use the seat as a rear facing seat. As illustrated in previous figures, the rear seating element can be rotated or moved into a stored position such that it can prevent intrusion into the rear occupant space of a vehicle. In numerous embodiments, the rear seating element 612 of one seat can be stored while the other is in a seating position. Moreover, since many embodiments may be configured with arm rests 614 that may be moveable connected or may be stationary, it can be appreciated that the arm rests may take on any number of different forms. For example, FIGS. 6A and 6B illustrate an embodiment of a seat 600 with armrests 614 that are integrated with or continuous with a seat frame element 616. In some embodiments the integrated arm rests 614 may be movable or rotatable similar to those illustrated previously. Additionally, it can be appreciated that the position of and movability of the arm resets, in accordance with some embodiments, can allow for improved ingress and egress from the vehicle. In numerous embodiments the seat frame element may also have integrated controls and safety elements such as seatbelt attachment points and/or other safety sensors and switches. Furthermore, as can be appreciated many embodiments of the rear seating element may incorporate a release mechanism that can allow for the complete removal of the rear seating element from the overall seat 600. This can allow for increased modularity of the seat design as well as provide for greater adaptability. For example, as can be readily appreciated, seating elements and various seating components can be manufactured with any number of materials including, but not limited to, metal, plastic, foam, cloth, leather, etc. Additionally, many components can be made of any desirable color or configuration. Accordingly, it can be advantageous to have a modular seat design such that individual elements such as the rear seating element 612, the seat back 606, and or the arm rests 614 can be removed or exchanged for different components of different colors or designs for a more customized appearance and feel.
The various embodiments described herein illustrate vehicle seating systems and elements that improve the overall comfort and modularity of vehicle seating. While the current disclosure may divide many of the functional and structural elements of seating systems, it will be understood that any seating element described, according to embodiments may combine, include or omit any of the described elements as desired by a specific vehicle design.
Embodiments of a Side-Facing Seat
Modularity and adaptability of the various components of a vehicle seating design can be advantageous from a variety of standpoints. Numerous embodiments of a vehicle seating design offer improved adaptability to be able to accommodate additional passengers when needed. For example. FIG. 7 illustrates an embodiment of a rear seating design 700 that incorporates a side facing seat 702. The side facing seat 702 can be an extension of the existing rear seat 704 such that a back support 706 is substantially continuous with the rear back support 708. Additionally, the side facing seat 702 can have a movable seat base 710 that can be configured in a number of different positions such that the top portion is substantially level with the rear seat base 712. It can be appreciated that the movement of the seat base 710 can be done in a number of different ways such as folding, rotating, sliding etc. to locate the seat base 710 into position. In numerous embodiments the side facing seat 702 can also be equipped with various safety devices such as a seat belt restraint latch 714 as well as any number of sensors. In some embodiments, the side facing seat may be an integral part of a vehicle door panel 716. In many embodiments, the side facing seat 702 can be folded into a stored position when not in use. Other embodiments can allow for the side facing seat 702 to be removed completely rather than stored an easily reattached when additional occupant space is required.
As was previously discussed the movement of the seat base can be done in a number of different methods such as folding, rotating, sliding, etc. such that the seat base 710 can be moved into the desired position. For example, FIGS. 7B through 7G illustrate a side seat 702 with different configurations such as a stored position (7B and 7E) to a fully extended position (7D and 7G) as well as a design position (7C and 7F). Although certain positions are illustrated, it should be understood that the seat base 710 can be placed in a number of different positions in a number of embodiments. In accordance with numerous embodiments, the side seat 702 can be connected to a door panel 716 of a vehicle. Accordingly, the seat base 710 of the side facing seat 702 can be moved into a stored position such that the front face of the seat base 718 is offset from the front face of the rear seat 719. Additionally, such configuration can provide for a portion of the seat base 710 to be stored or located within a cavity 720 of the door panel 716. When the seat base 710 is in a stored position, it can be appreciated that egress and ingress of the vehicle can be made easier since the seat base 710 is not extended and in the way of an occupant that is entering the vehicle.
In many embodiments, the seat base 710 of the side seat 702 can have what can be considered a design position as illustrated in FIGS. 7C and 7F. In the design configuration the seat base 710 can be moved into a position such that the front face 718 is continuous with the front face 719 of the main rear seat 712. Accordingly, such embodiments or positions can provide for a more aesthetic appearance in the rear seat configuration. Although the design configuration may appear to be aesthetic, it could be appreciated that an occupant could use such configuration to sit if needed.
As can be appreciated, the rear seat 702 can be configured to allow an occupant to fully occupy the seat 702 during a stationary position as well as while moving. As such, many embodiments may allow for the seat base 710 to be moved into a deployed position as illustrated in FIGS. 7D and 7G. In a deployed position, the seat base is extended such that the full seat base 710 is exposed and the front face 718 is offset from the front face of the rear seat 719. As such, an occupant can safely utilize the seat and access the various safety devices while using the seat. As can be further appreciated the side seat 702 can be moved from one position to the other based on the desired position. This can be further illustrated by the bi-directional arrows in FIGS. 7E to 7G.
Since various embodiments allow for the side seat to be moved between a stored and a deployed position, it can be appreciated that a number of different methods and/or mechanisms can be employed to move the seat from one position to the other. For example, FIG. 7H illustrates an open bottom view of a side seat base 710. In many embodiments the seat base 710 can be situated on a support element 722 that is connected to one or more rails 724 that can allow for the seat base 710 to slide in and out of the number of different positions. Additionally, many embodiments may incorporate a locking mechanism that can have multiple parts. For example, many embodiments may have a locking lever 726 that is fixed to the seat 710 and moves with the movement of the seat 710. Such embodiments may also incorporate a fixed element 727 that may have a multiple holes 728 that can engage with corresponding teeth on the locking lever. As can be appreciated, the locking mechanism 726 can be activated by an activation device 730 such as a lever with a button or pad 731 that an occupant can engage with. In some embodiments, the activation device 730 can be a push button or any device that can actively engage with the locking mechanism 726 to allow the movement of the locking mechanism. Additionally, both the locking mechanism 726 and the activation device 730 can have one or more resilient members 732 such as a spring that can allow for the respective component to move between an initial and an engagement position. Such resilient member 732 can be positioned around a central pivot point 734 or may be positioned anywhere along the respective component to afford the desired movement and subsequent engagement.
Although a specific configurations of a side facing seat with the various components that allow the movement of such are illustrated, it should be understood that any combination of materials, components, and/or designs can be used in a number of embodiments. For example, some embodiments may use extruded aluminum in the manufacturing of the various structural elements such as the slides or rails 724. Other embodiments may use steel or any other material that may be suitable for the form, fit, and function of the side facing seat. Additionally, some embodiments may use any number of different activation devices and locking mechanisms. For example, some embodiments may us electronic activation devices that can electronically activate a locking mechanism to lock the seat in to position. Such devices can include switches that activate the locking device. Likewise, some embodiments may use locking pins or other type of locking mechanisms rather than a rotating lever. Furthermore, many embodiments may use one or more assistant type devices to help move the seat along the rails. For example, some embodiments may use a hydraulic piston type device and/or a spring or resilient element. Other embodiments can use some type of drive system such as a gear drive and a motor connected to the rails and/or seat base such that the drive system can move the seat base in and out of the various positions as described previously.
The various embodiments described herein illustrate a side facing seat device along with various elements that improve the overall comfort and modularity of side facing seat. While the current disclosure may divide many of the functional and structural elements of side facing seats, it will be understood that any element described, according to embodiments may combine, include or omit any of the described elements as desired by a specific seating design.
Embodiments of Safety Elements
As can be readily appreciated, modern vehicles require a substantial number of safety features designed to protect the vehicle occupants in the event of a crash. Previously mentioned were things such as sensors or switches designed to help control the movement of the vehicle. Accordingly, many embodiments of vehicle seating elements described herein can be configured with any number of sensors and or switches that can be connected to a number of different vehicle safety systems to help notify a driver as well as prevent vehicle movement. For example, FIG. 8 illustrates a top view of a vehicle passenger compartment 800 with a front seating system 802 and a rear seating system 804. The rear seating system 804 may be equipped with a side facing seat 806 similar to embodiments previously described. Accordingly, the novel side facing seat 806 may require an occupant detection sensor 808 placed somewhere in the seating element. Occupant detection sensors have been used in many vehicle designs to indicate the use or deactivation of things such as airbags that can help prevent injury to the occupant. Accordingly, side facing seats 806 can use similar sensors to indicate to a driver whether the side facing seat 806 is in an open position and whether or not it is occupied. Furthermore, the driver could be alerted to the activation or inactivation of the safety restraint device. This can help driver's be more aware of occupant positioning before moving the vehicle. Additionally, many sensors and switches can be integrated into a larger vehicle lockout system that can prevent the overall vehicle from moving if occupants are detected but not safely in a position to move. It can be readily appreciated that rear seats 810 can also be equipped with occupant detection sensors 808.
Not only can rear and side seats be equipped with a number of sensors to detect occupants, front seats can take on any number of different configurations that may require a different subset of sensors and/or lockout mechanisms. For example, FIG. 9 illustrates perspective views of front seats 900 with a number of different sensors to help improve occupant safety and/or comfort. For example some embodiments may include occupant position sensors 902 similar to those described in FIG. 8. Other seats 900 may include heating elements 904 that can be activated when the occupant position sensor 902 registers that an occupant is positioned in the seat 900. Additionally, many embodiments can include safety restraint latches 906 that have separate sensors to indicate the use or not of the latch. In many embodiments the rear seat element 908 can be equipped with an occupant detection sensor. The occupant detection sensor can be subsequently connected to an overall vehicle lockout system such that when the rear seat element 908 is opened and/or occupied that the vehicle can be prevented from moving. This can be tied to mechanical locking mechanisms or electrical lockouts that prevent electrical circuits from closing and activating drive systems. Although not illustrated, it can be appreciated that many seating elements can be equipped with one or more additional safety devices such as restraints and/or airbags that can be deployed in a number of ways to protect the occupant.
As can be appreciated with the numerous systems and sensors that can be involved in the various seating systems, FIG. 10 illustrates an embodiment of a system process by which some embodiments may engage a vehicle lockout or notification system. For example, occupant sensors can detect the position of an occupant (1002). If no occupant is detected (1004) then a number of vehicle engagement systems can be deactivated (1006). Some engagement systems can include vehicle lockout systems or driver notification systems. If an occupant is detected (1008) then the various engagement systems can be activated (1009). In some embodiments, the system may look to see if the rear facing seat is activated or placed in an open position (1010). If the rear facing seat is open (1011) then the vehicle safety interlock can be engaged (1012) and prevent the vehicle from moving or engaging the drive system. In addition to the vehicle interlock system, an opened rear facing seat can activate visual indicator (1014) such as an illuminated light or even a notification on a mobile device. Other indicators could include audible indicators that can be used in conjunction with visual indicators to notify the driver that the vehicle interlock system is engaged and the drive system is disengaged. Alternatively, if the rear facing seat is not open (1016) then the interlock system can be prevented from engaging and allow the drive system to engage (1018). Similar to the visual and/or audible indicators for the open position, visual and/or audible go indicators can be activated (1020) to notify the driver that it is safe to operate the vehicle. Although the process is described with respect to the rear facing seat, it should be understood that such processes may be used for other seating elements such as a side facing seat or rear seats according to various embodiments.
The various embodiments described herein illustrate vehicle seating systems and integrated safety systems that can improve the overall comfort and modularity of vehicle seating. While the current disclosure may divide many of the functional, structural, and safety elements of seating systems, it will be understood that any seating element described, according to embodiments may combine, include or omit any of the described elements as desired by a specific vehicle design
