BACKGROUND

Vehicles may be subject to impact tests to test the movement of vehicle occupants. Such tests may be standardized by various governmental or industry organizations. Some test, for example, measure the movement of vehicle occupants during certain vehicle impacts that move the vehicle occupants in cross-vehicle directions. These tests include certain side impact tests and oblique impact tests.

As one example, the National Highway Traffic Safety Administration (NHTSA) sets forth a standardized test procedure for a side pole crash test, which is designed to simulate a vehicle experiencing certain side impacts with a pole. Another example that tests cross vehicle movement of the occupant is the European New Car Assessment Program (EuroNCAP). The Euro NCAP has certain side impact tests standardized to test the far side impact condition and evaluate occupant kinematics relative to other occupants.

DETAILED DESCRIPTION

A vehicle includes a vehicle seat that includes a seatback that defines an occupant seating area. The seatback includes an inboard bolster and an outboard bolster spaced from the inboard bolster in a cross-seat direction with the occupant seating area between the inboard bolster and the outboard bolster. An arm is rotatably supported by the inboard bolster. The vehicle includes a computer that includes a processor and a memory storing instructions executable by the processor to detect an occupant in the occupant seating area and, based on the detection of an occupant in the occupant seating area, rotate the arm toward the occupant seating area in response to detection of certain vehicle impacts

The inboard bolster may be elongated along an upright axis and the arm may be rotatable relative to the inboard bolster toward the occupant seating area about the upright axis. The arm may be elongated along the upright axis.

The vehicle may include an actuator supported by the inboard bolster and configured to rotate the arm toward the occupant seating area. The arm may be supported by the actuator. The actuator may be a pyrotechnic actuator.

With reference to the Figures, wherein like numerals indicate like parts throughout the several views, a vehicle10includes a vehicle seat12that includes a seatback14that defines an occupant seating area16. The seatback14includes an inboard bolster18and an outboard bolster20spaced from the inboard bolster18in a cross-seat direction with the occupant seating area16between the inboard bolster18and the outboard bolster20. An arm22is rotatably supported by the inboard bolster18. The vehicle10includes a computer70that includes a processor and a memory storing instructions executable by the processor to detect an occupant in the occupant seating area16and, based on the detection of an occupant in the occupant seating area16, rotate the arm22toward the occupant seating area16in response to detection of certain vehicle impacts.

Since the memory stores instructions to rotate the arm22toward the occupant seating area16in response to detection of certain vehicle impacts, the arm22urges an occupant seated on the seatback14in the cross-seat direction toward the outboard bolster20. As an example, the memory may store instructions to rotate the arm22toward the occupant seating area16in response to detection of certain vehicle side impacts.

With reference toFIG.1, the vehicle10may be any type of passenger or commercial automobile such as a car, a truck, a sport utility vehicle, a crossover, a van, a minivan, a taxi, a bus, etc.

The vehicle10includes a body24defining a passenger cabin (not numbered) to house occupants, if any, of the vehicle10. The body24may include a roof (not numbered) and a floor with the roof defining an upper boundary of the passenger cabin and the floor defining a lower boundary of the passenger cabin. The body24includes doors openable to allow ingress to and egress from the passenger cabin.

The passenger cabin may extend across the vehicle10, i.e., from one side to the other side of the vehicle10. The passenger cabin includes a front end (not numbered) and a rear end (not numbered) with the front end being in front of the rear end during forward movement of the vehicle10.

With reference toFIG.1, the passenger cabin may include at least two vehicle seats12including a first vehicle seat12and a second vehicle seat12set forth above. The adjective “first” and “second” is used as an identifier to distinguish between two vehicle seats12of the vehicle10and does not indicate order or importance. Common numerals are used to identify common features of the first vehicle seat12and the second vehicle seat12in the Figures. The vehicle seats12, e.g., the first vehicle seat12and the second vehicle seat12, may be arranged as a driver seat and a passenger seat. The vehicle seats12may be supported by the vehicle floor, as shown in the example in the Figures. The vehicle seats12may be arranged in any suitable arrangement in the passenger cabin. As in the example shown in the Figures, one or more of the vehicle seats12may be at the front end of the passenger cabin, e.g., the driver seat and/or the passenger seat. In other examples, one or more of the vehicle seats12may be behind the front end of the passenger cabin, e.g., at the rear end of the passenger cabin. The vehicle seats12may be movable relative to the vehicle floor to various positions, e.g., movable fore-and-aft. The vehicle10may be of any suitable type, e.g., a bucket seat.

Each vehicle seat12includes the seatback14and a seat bottom26. The seatback14may be supported by the seat bottom26and may be stationary or movable relative to the seat bottom26. Specifically, the seatback14may be fixed relative to the seat bottom26in an upright position or moveable relative to the seat bottom26to the upright position. The upright position is a position of the seatback14that supports an occupant in a seated position. As an example, the seatback14in the upright position may be elongated within degrees of parallel to a vertical axis A1. In some examples, the seatback14is rotatable from the upright position to a reclined position in which the seatback14is elongated between degrees of parallel and horizontal. In examples including rows of seats, e.g., the rear row of seats, the seatback14sof adjacent seats in the row are adjacent each other and arranged cross-vehicle.

The vehicle seats12each include an inboard side28and an outboard side30spaced from each other in the cross-seat direction, e.g., in a cross-vehicle direction when the seat is forward facing. The seatback14includes a front32extending from the inboard side28to the outboard side30and a rear34extending from the inboard side28to the outboard side30. As shown in the Figures, when the seatback14is forward-facing in the upright position, the front32of the seatback14faces vehicle forward and the rear34of the seatback14faces vehicle rearward. The inboard side28is vehicle-inboard of the outboard side30when the seatback14is forward facing.

The seatback14and the seat bottom26define the occupant seating area16. The occupant seating area16is in a seat-forward direction of the seatback14and above the seat bottom26. Specifically, the seatback14defines the occupant seating area16between the inboard side28and the outboard side30. The front32of the seatback14between the inboard side28and the outboard side30defines the occupant seating area16. The occupant seating area16is the area occupied by an occupant when properly seated on the vehicle seat12.

The seatback14includes a top36between the inboard side28and the outboard side30. Specifically, the top36extends from the inboard side28to the outboard side30. The seatback14is elongated from the seat bottom26to the top36of the seatback14. In other words, as shown in the Figures, the top36may terminate at the inboard side28and the outboard side30.

The seatback14may have bolsters, i.e., the inboard bolster18and the outboard bolster20. The outboard bolster20is spaced from the inboard bolster18in the cross-seat direction. The occupant seating area16is between the inboard bolster18and the outboard bolster20. The bolsters, e.g., the inboard bolster18and outboard bolster20, are elongated, and specifically, are elongated along an upright axis A2when the seatback14is in the upright position. The bolsters18,20define cross-seat boundaries of the seatback14, i.e., the seatback14terminates at the bolsters18,20. The bolsters18,20may extend in a seat-forward direction relative to the occupant seating area16, i.e., on opposite sides of the torso and shoulders of an occupant seated on the vehicle seat12. The inboard bolster18is vehicle-inboard of the outboard bolster20when the seatback14is forward facing.

The seat12includes a frame38and a covering40supported by the frame38. Specifically, the seatback14includes the frame38, i.e., a seatback14frame38, and the covering40. The seat bottom26may also include the frame38and the covering40. The frame38may include tubes, beams, etc. Specifically, the frame38includes a pair of upright frame members42. The upright frame members42are spaced from each other, and the frame38includes at least one cross-beam44extending between the upright frame members42. The frame38, including the upright frame members42, may be of any suitable metal (e.g., steel, aluminum, etc.), plastic material (e.g., carbon fiber reinforced plastic (CFRP), glass fiber-reinforced semi-finished thermoplastic composite (organosheet), etc.), etc. The covering40may include upholstery and padding. The upholstery may be cloth, leather, faux leather, or any other suitable material. The upholstery may be stitched in panels around the frame38. The padding may be between the covering40and the frame38and may be foam or any other suitable material. The covering40conceals the arm22when the arm22is in an undeployed position and when the arm22is in a deployed position. The outboard bolster20and the inboard bolster18each include the frame38and the covering40supported on the frame38. The extension of the bolsters18,20relative to the occupant seating area16may be defined by the upright frame members42and/or the covering40. In the example shown in the Figures, the size and shape of both the upright frame members42and the covering40form the bolsters.

As set forth above, the seatback14, and specifically the frame38, is elongated along the upright axis A2when the seatback14is in the upright position. Specifically, the upright frame members42of the frame38are elongated along the upright axis A2when the seatback14is in the upright position. As described above, in the upright position, the seat12may be occupied by an occupant and the seatback14supports the occupant in the seated position. The top36of the seatback14is above the seat bottom26in the upright position. In the examples shown in the Figures, the front seats are in the upright position.

The vehicle10may include a middle console46between the first vehicle seat12and the second vehicle seat12. The middle console46may be on a longitudinal midline of the vehicle10. With reference to the example shown inFIGS.2A-2Bthe middle console46is adjacent the vehicle seat12, i.e., with nothing between the middle console46and the vehicle seat12.

The middle console46may be supported by the floor. Specifically, in such examples, the middle console46extends upwardly from the floor between the first vehicle seat12and the second vehicle seat12. In such an example, the middle console46abuts the floor and may be connected to the floor, e.g., with fasteners such as threaded fasteners. The middle console46may be, for example, plastic such as acrylonitrile butadiene styrene (ABS), vinyl, etc. The middle console46may include a class-A surface exposed to the passenger cabin. A class-A surface is a finished surface free of unaesthetic blemishes and defects and exposed to view by a vehicle occupant seated in the vehicle10. The middle console46may include cup holders and may support vehicle controls, e.g., a gear shifter, window controls, HVAC controls, multimedia controls, etc.

The middle console46may include an armrest48. The armrest48is above the middle console46and, for example, may be supported by the middle console46. The armrest48is designed to support the arm22of occupants of the vehicle seated in the vehicle seats12. Specifically, the armrest48is sized, shaped, and positioned to support the arm22of the occupant. The armrest48may be upholstered, e.g., with a covering of vinyl, leather, etc.

The inboard bolster18may be between the outboard bolster20and the middle console46. With reference toFIGS.2A-2B, the inboard bolster18is adjacent the middle console46when forward facing. In examples including the first vehicle seat12and the second vehicle seat12, the middle console46is between the second vehicle seat12and the inboard bolster18of the first vehicle seat12when the first vehicle seat12and the second vehicle seat12are forward facing.

With reference toFIGS.3-6, the vehicle10includes an arm assembly50. The arm assembly50includes the arm22and an actuator52. As set forth below, the arm22is rotatably supported by the inboard bolster18and, based on the detection of an occupant in the occupant seating area16, the actuator52rotates the arm22toward the occupant seating area16in response to detection of certain vehicle impacts.

The arm22may be supported by the frame38between the frame38and the covering40. Specifically, the arm22is rotatably supported by the inboard bolster18. The arm22may be rotatable relative to the inboard bolster18toward the occupant seating area16about the upright axis A2from the undeployed position to the deployed position. For example, the arm22may be rotatably supported by the inboard bolster18by a hinge54disposed between the arm22and the inboard bolster18, as described further below. For example, as illustrated inFIG.5, the actuator52may include a housing56having a base58mounted to the frame38and the hinge54may include bearing-ends60rotatably connected to the housing56. As described further below, the actuator52rotates the bearing-ends60relative to the housing56to rotate the arm22relative to the housing56and the frame38from the undeployed position to the deployed position.

The hinge54may be configured to permit limited rotation of the arm22about the upright axis A2. Specifically, the hinge54stops the rotation of the arm22in the deployed position. For example, the hinge54may include a stop62that stops rotation of the arm22in the deployed position. The stop62is designed to stop rotation of the arm22relative to the inboard bolster18in the deployed position as the arm22rotates from the undeployed position to the deployed position. In the example shown in the Figures, specifically with reference toFIGS.5-6B, the stop62protrudes from the bearing-end60. The stop62is spaced from the base58of the actuator52in the undeployed position and abuts the base58of the actuator52in the deployed position.

The arm22may be supported by the frame38. Specifically, the arm22may be supported by the upright frame member42of the inboard bolster18. In other words, the weight of the arm22may be borne by the upright frame member42. The arm22may extend in the seat-forward direction along the occupant seating area16in the undeployed position. In the example shown in the Figures, the arm22is between the frame38and the covering40. Specifically, the covering40may conceal the arm22, i.e., completely covering40the arm22to separate the arm22from the occupant seating area16and the passenger cabin. The arm22is between the frame38and the covering40, e.g., concealed, in the undeployed position and may be between the frame38and the covering40, e.g., concealed, in the deployed position, as shown in the example in the Figures. The arm22may move the covering40toward the occupant seating area16when the arm22rotates toward the occupant seating area16. The arm22may be, for example, plastic such as acrylonitrile butadiene styrene (ABS), vinyl; metal; composite; etc.

With reference toFIGS.2-5, the arm22includes a top edge64and a bottom edge66. The top edge64faces the top of the seatback14and the bottom edge66faces the floor of the vehicle10when the vehicle seat12is in the upright position. The arm22may include two lateral sides68spaced from each other and each extending from the top edge64to the bottom edge66. The arm22terminates at the top edge64, the bottom edge66, and the two lateral sides68. As an example, the arm22may be crescent shaped in cross section. As another example, the arm22may be rectangular in cross-section. The arm22may be elongated from the top edge64to the bottom edge66. Specifically, the arm22may be elongated along the upright axis A2, as shown in the example in the Figures. Specifically, the arm22may be elongated along the general upright position of the seatback14. In the example shown in the Figures, the arm22is elongated along the inboard side28of the seatback14. The arm22may have an inboard side28that faces the occupant seating area16when the vehicle seat12is in any position.

As set forth above, the arm assembly50may include the actuator52to deploy the arm22from the undeployed position to the deployed position. Specifically, the actuator52is activated by the computer70of the vehicle10, e.g., a restraints control module, as described further below. In the example shown in the Figures, the actuator52rotates the arm22from the undeployed position to the deployed position. In other examples, in addition to or in the alternative to rotation, the actuator52may translate the arm22from the undeployed position to the deployed position.

As set forth above, the actuator52includes the housing56. The housing56may include the base58, as introduced above, and a barrel72supported by the base58. The base58may be fixed to the frame38, as described below, and the barrel72may be supported by the base58on the frame38, i.e., the weight of the barrel72is borne by the base58. The bearing-ends60of the hinge54may be rotatably engaged with the barrel72such that the bearing-ends60are rotatable relative to the barrel72from the undeployed position to the deployed position.

The actuator52is supported by the seatback14. Specifically, the actuator52may be supported by the inboard bolster18. As an example, shown in the Figures, the actuator52is fixed to the frame38of the inboard bolster18. Specifically, in the example shown in the Figures, the actuator52is fixed to the upright frame member42of the inboard bolster18. The actuator52moves as a unit with the frame38in the event the seatback14is adjusted relative to the seat bottom26between the upright position and reclined positions. As an example, the actuator52may be fixed to the upright frame member42with threaded fasteners, clips, brackets, etc.

The arm22is supported by the actuator52. In other words, the weight of the arm22may be borne by the actuator52. In the example shown in the Figures, the actuator52is rotatably coupled to the arm22to rotate the arm22along the upright axis from the undeployed position to the deployed position.

The actuator52may be engaged with the arm22and configured to rotate the arm22toward the occupant seating area16. Specifically, the actuator52rotates the arm22about the upright axis from the undeployed position to the deployed position in response to detection of certain vehicle impacts, as described further below. As the arm22rotates into the occupant seating area16, the arm22rotates toward the occupant of the seat. In some examples, the arm22may force covering40of the bolster18,20to contact the occupant, i.e., an inboard side28of the occupant. In such an event, a seated occupant may be urged in the cross-seat direction toward the outboard bolster20in response to a certain vehicle impact. In examples including the middle console46, a seated occupant may be urged in the cross-seat direction away from the middle console46in response to a certain vehicle impact.

The actuator52includes a driving mechanism74that imparts rotation on the arm22. The driving mechanism74may be, for example, housed in the housing56, and more specifically, in the barrel72. In such an example the driving mechanism74is rotatably engaged with the hinge54, e.g., the bearing-ends60, to rotate the hinge54relative to the barrel72. In other words, the actuator52is a rotary actuator52.

As an example, the actuator52may be a pyrotechnic actuator52. In other words, the actuator52is pyrotechnically actuated. Specifically, the driving mechanism74of the actuator52is a pyrotechnic device that includes a pyrotechnic charge (not shown). The pyrotechnic charge may be combustible to produce a gas. The pyrotechnic charge may be formed of a solid mixture of substances that, when ignited, react to produce the gas. For example, the pyrotechnic charge may be formed of sodium azide (NaNO3), potassium nitrate (KNO3), and silicon dioxide (SiO2), which react to form nitrogen gas (N2). In such an example, the actuator52, specifically the pyrotechnic device, includes a rotary cylinder and the pyrotechnic charge that rotates the rotary cylinder. When the actuator52is activated, as described below, the actuator52moves the arm22from the undeployed position to the deployed position. The pyrotechnic charge rotates the hinge54toward the occupant seating area16, rotating the arm22from the undeployed position to the deployed position.

As another example, the actuator52may be motorized. In other words, the actuator52is a motorized actuator52. In such an example, the driving mechanism74of the actuator52includes a motor, e.g., a DC motor, and may include gears. In such an example, the motor is activated to rotate the arm22relative to the frame38, e.g., by imparting rotational force on the bearing-ends60of the hinge54. In such an example, the actuator52may be resettable. In other words, the motor may move the arm22from the deployed position to the undeployed position to reset the actuator52for re-use.

With reference toFIG.7, the vehicle10includes the computer70including a processor and a memory. The computer70may be a restraints control module. The memory includes one or more forms of computer readable media, and stores instructions executable by the computer70for performing various operations, including as disclosed herein and including, for example, method shown inFIG.8and described below. For example, the computer70may be a generic computer70with a processor and memory as described above and/or may include an electronic control unit ECU or controller for a specific function or set of functions, and/or a dedicated electronic circuit including an ASIC (application specific integrated circuit) that is manufactured for a particular operation, e.g., an ASIC for processing sensor data and/or communicating the sensor data. In another example, the computer70may include an FPGA (Field-Programmable Gate Array) which is an integrated circuit manufactured to be configurable by a user. Typically, a hardware description language such as VHDL (Very High-Speed Integrated Circuit Hardware Description Language) is used in electronic design automation to describe digital and mixed-signal systems such as FPGA and ASIC. For example, an ASIC is manufactured based on VHDL programming provided pre-manufacturing, whereas logical components inside an FPGA may be configured based on VHDL programming, e.g., stored in a memory electrically connected to the FPGA circuit. In some examples, a combination of processor(s), ASIC(s), and/or FPGA circuits may be included in the computer70. The memory may be of any type, e.g., hard disk drives, solid state drives, servers, or any volatile or non-volatile media. The memory may store the collected data sent from the sensors. The memory may be a separate device from the computer70, and the computer70may retrieve information stored by the memory via a network76in the vehicle10, e.g., over a CAN bus, a wireless network, etc. Alternatively or additionally, the memory may be part of the computer70, e.g., as a memory of the computer70.

As shown inFIG.7, the computer70is generally arranged for communications on the vehicle communication network76that may include a bus in the vehicle10such as a controller area network CAN or the like, and/or other wired and/or wireless mechanisms. Alternatively or additionally, in cases where the computer70includes a plurality of devices, the vehicle communication network76may be used for communications between devices represented as the computer70in this disclosure. Further, as mentioned below, various controllers and/or sensors may provide data to the computer70via the vehicle communication network76.

The vehicle10may include at least one impact sensor80for sensing certain impact of the vehicle10. The computer70is in communication with the impact sensor80and the actuators52. The computer70may activate the actuator52, e.g., provide an impulse to the pyrotechnic charge, a command to the motor, etc., when the impact sensor80senses certain impact of the vehicle10. Alternatively, or additionally to sensing certain impacts, the impact sensor80may be configured to sense certain impact prior to impact, i.e., pre-impact sensing. The impact sensor80may be of any suitable type, for example, post contact sensors such as accelerometers, pressure sensors, and contact switches; and pre-impact sensors80such as radar, LIDAR, and vision sensing systems. The vision sensing systems may include one or more cameras, CCD image sensors, CMOS image sensors, etc. The impact sensor80may be located at numerous points in or on the vehicle10.

The vehicle10may include at least one occupancy sensor78. The occupancy sensor78configured to detect occupancy of the vehicle seats12, e.g., detect an occupant in the occupant seating area16. The occupancy sensor78may be visible-light or infrared cameras directed at the vehicle seat12, weight sensors supported by the seat bottom26, sensors detecting whether a seatbelt assembly for the seat is buckled, or other suitable sensors. The occupancy sensor78provides data to the computer70specifying whether the vehicle seat12is occupied or unoccupied.

With reference toFIG.8, the vehicle computer70stores instructions to control components of the vehicle10according to the method800shown inFIG.8. Use of “in response to,” “based on,” and “upon determining” herein indicates a causal relationship, not merely a temporal relationship.

With reference to block805ofFIG.8, the method includes detecting an occupant in the occupant seating area16. Specifically, the occupancy sensor78, as described above, may detect occupancy of the occupant in the occupancy seating area. In such an example, the occupancy sensor78communicates the detection of the occupant to the computer70, e.g., by sending a signal over the network76. In the event no occupant is detected, the method800returns to start. In the event an occupant is detected, the method800proceeds to block810. In block805, the method800may also include detecting an occupant in the occupant seating area16of the first vehicle seat12and/or the occupant seating area16of the second vehicle seat12.

In block810, the method includes detecting certain vehicle impacts. Specifically, the impact sensor80, as described above, may detect certain vehicle impacts. In such an example, the occupancy sensor78communicates the detection of certain vehicle impacts to the computer70, e.g., by sending a signal over the network. In the event a certain vehicle impact is not detected, the method800returns block805or to start. In the event an occupant is detected, the method800proceeds to block815.

In block815, based on the detection of an occupant in the occupant seating area16, the method includes rotating the arm22toward the occupant seating area16in response to detection of certain vehicle impacts. In examples in which the method800includes detecting an occupant in the occupant seating area16of the first vehicle seat12and the second vehicle seat12, block815includes rotating the arm22of the first vehicle seat12and/or the second vehicle seat12based on occupancy detection. In block815, in examples in which the actuator52is a pyrotechnic actuator52, block815includes the computer70providing an impulse to the pyrotechnic charge to rotate the arm22as described above. In examples in which the actuator52is a motorized actuator52, block815includes the computer70providing a command to activate the motor to rotate the arm22as described above.

In examples in which the actuator52is resettable, the method800may include blocks820and825. In block820, the method800includes determining that the event that triggered deployment of the arm22is complete. This may be based, for example, on occupant input, service technician input, and/or sensor detection in the vehicle10. When the event is complete, the method800proceeds to block825in which the actuator52is reset to the undeployed position. As an example, in examples in which the actuator52is a motorized actuator52, block825includes the computer70providing a command to activate the motor to rotate the arm22from the deployed position to the undeployed position. When the arm22is in the undeployed position, the method800may return to start.
