Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priorities from Japanese Patent Application No. 2014-241377 filed on Nov. 28, 2014, the entire subject matters of which is incorporated herein by reference. 
       TECHNICAL FIELD 
       [0002]    The present disclosure relates to a vehicle seat including a seat back upraised from a seat cushion and an accommodating section which is provided in the seat back and in which other installable component can be arranged. 
       BACKGROUND 
       [0003]    In many vehicles, a floor console (an example of the installable component) is disposed along with a vehicle seat in consideration of convenience to occupants or the like. For example, in a vehicle disclosed in JP-A-H9-277878, a floor console is disposed between a driver seat and a passenger seat which are vehicle seats. Each of the driver seat and the passenger seat as vehicle seats includes a seat cushion and a seat back rising upward from the seat cushion. The floor console is a cubic box member which is formed by injection-molding an appropriate resin material and plural engaging protrusions are formed on the bottom end thereof. In the related art, a resin floor-shaping member is disposed on a vehicle floor surface and locking holes into which the engaging protrusions can be fitted are formed in the floor-shaping member. By inserting and fitting the engaging protrusions into the locking holes in the vertical direction, the floor console can be disposed on the vehicle floor surface between the driver seat and the passenger seat. 
         [0004]    In the above-mentioned configuration, for example, in consideration of the shape or size of the vehicle seat or the like, a hole-shaped or cutout-shaped accommodating section in which the floor console is arranged may be provided in the seat back. The floor console is disposed in the accommodating section and the vehicle seat and the floor console are fixed to the vehicle floor surface. In this state, in consideration of appearance or the like, it is preferable that the floor console is disposed with an appropriate posture at an appropriate place in the accommodating section. However, in the related art, the floor console is fixed to only the vehicle floor surface. Accordingly, for example, when the positional relationship between the vehicle floor surface and the accommodating section varies, the floor console may not be appropriately disposed in the accommodating section. 
       SUMMARY 
       [0005]    The present disclosure is made in consideration of the above-mentioned circumstances, and one of objects of the present disclosure is to appropriately position and dispose other installable component in an accommodating section of a seat back. 
         [0006]    According to an illustrative embodiment of the present disclosure, there is provided a vehicle seat including: a seat cushion on which buttocks of an occupant is placed; and a seat back that is upraised with respect to the seat cushion, the seat back including: a seat pad having elasticity and support a back of the occupant; a reinforcing member that is formed by a linear or planer member and reinforces the seat pad; and an accommodating section provided in the seat pad and receives an installable component that is configured as a separate body that is separate from the seat back. The reinforcing member has an engaging portion that protrude into the accommodating section, the engaging portion being configured to be engageable with an engaged portion that is provided on the installable component. The vehicle seat is configured to allow the installable component to be installed in the accommodating section while positioning the installable component with respect to the accommodating section in a state where the engaging portion and the engaged portion are engaged with each other.

The respective configurations will be described in detail. 
         [0018]    The seat covers  6 Sa to  6 Sc are surface materials covering proper places of the seat pad  6 P to be described later as illustrated in  FIG. 1  and can be formed of fabric (such as woven fabric, knitted fabric, and non-woven fabric) or leather (such as natural leather and synthetic leather). The seat pad  6 P is a member capable of elastically supporting an occupant as illustrated in  FIG. 2  and can be formed of a foamed resin such as a polyurethane foam (with a density of 10 kg/m3 to 60 kg/m3). The seat pad  6 P according to this embodiment has a rectangular shape which is longer in a seat width direction in a front view and has an outer shape in which the seat backs  6   a  and  6   b  and the intermediate section  6   c  are formed as a unified body. 
         [0019]    As illustrated in  FIGS. 1 to 4 , the accommodating section  10  is a part in which the following floor console  40  (the installable component) can be disposed. The accommodating section  10  according to this embodiment is a cut-out part which is formed below the intermediate section  6   c  between the first seat back  6   a  and the second seat back  6   b  and penetrates the seat pad  6 P in the thickness direction thereof. The accommodating section  10  includes an opened bottom side, a top side portion  10   a,  a first side portion  10   b,  and a second side portion  10   c.  The top side portion  10   a  is formed by the bottom surface of the intermediate section  6   c  and is disposed in a bridge shape between the first seat back  6   a  and the second seat back  6   b.  The first side portion  10   b  is a part which is formed by the lower part of a seat inside surface of the first seat back  6   a.  The second side portion  10   c  is a part which is formed by the lower part of a seat inside surface of the second seat back  6   b  and is disposed to face the first side portion  10   b.  In this embodiment, a space part  10   d  surrounded with the top side portion  10   a  and both side portions  10   b  and  10   c  has a size capable of accommodating the floor console  40  and is opened to a front side (the seating surface side) on which a back of the occupant is supported and to a back side (the back surface side) of the seat back  6   a,    6   b  and  6   c.  The floor console  40  to be described later is fixed to the vehicle floor surface FL in a state in which the back part thereof is disposed in the accommodating section  10 . 
         [0020]    The reinforcing member  20  is a member reinforcing the seat pad  6 P as illustrated in  FIG. 3  and can be formed of a material having excellent rigidity (such as metal or hard resin). The reinforcing member  20  according to this embodiment is a substantially rectangular frame in which plural wire members (wire) to be described later are connected vertically and horizontally and includes a pair of basic parts  20 A and  20 B and a bridging part  20 C. The basic parts  20 A and  20 B (details of which will be described later) are parts for reinforcing the seat pads of the corresponding seat backs  6   a  and  6   b.  The bridging part  20 C (details of which will be described later) is a part for reinforcing the seat pad parts constituting the seat backs  6   a  and  6   b  and the intermediate section  6   c  and is disposed over the pair of basic parts  20 A and  20 B. The reinforcing member  20  can be formed in an embedded type as a unified body with the seat pad  6 P, for example, at the same time as molding the seat pad  6 P. For example, the reinforcing member  20  is disposed at an appropriate position in a molding machine (not illustrated) of the seat pad  6 P. In this state, by supplying a molding material (liquid resin) of the seat pad  6 P to the machine and foaming the molding material, the reinforcing member  20  can be unified with the seat pad  6 P in an embedded type while molding the seat pad  6 P. 
         [0021]    As illustrated in  FIG. 3 , the basic part  20 A of the first seat back  6   a  and the basic part  20 B of the second seat back  6   b  have substantially the same configuration. Accordingly, the basic part  20 A will be described below as an example, and the same elements as in the basic part  20 B will be referenced by the same reference numerals and detailed description thereof will not be repeated. The basic part  20 A according to this embodiment includes plural vertical wires (a first vertical wire WH 1  to a fourth vertical wire WH 4 ), plural lower horizontal wires WD 1  to WD 3 , and plural upper horizontal wires WT 1  to WT 5 . 
         [0022]    The plural vertical wires WH 1  to WH 4  are wires extending in a seat height direction in a state in which the seat is upright. In this embodiment, the first to fourth vertical wires WH 1  to WH 4  are arranged in parallel from the seat depth side to the outside in this order as indicated by a direction of arrow L in  FIG. 3  (see a direction of arrow R in  FIG. 3  as for the second seat back  6   b ). The first vertical wire WH 1  and the fourth vertical wire WH 4  extend in a straight line shape in the vertical direction of the seat and are disposed at both ends which are large frame parts of the first seat back  6   a . The second vertical wire WH 2  and the third vertical wire WH 3  have linear upper parts and lower parts inclined in a direction in which both come near to each other, and are disposed between the first vertical wire WH 1  and the fourth vertical wire WH 4 . The vertical wires other than the fourth vertical wire WH 4  are bent to the back side of the seat at the top end to reinforce the top surface side of the seat pad  6 P. The first vertical wire WH 1  and the third vertical wire WH 3  are disposed to protrude downward from the lower horizontal wire WD 1  to be described later which is disposed at the lower end of the seat. The lower ends of the first vertical wire WH 1  and the third vertical wire WH 3  are curved in a substantially U shape and are fixed to the fixing member  9  using bolt materials BM. 
         [0023]    The plural horizontal wires WD 1  to WD 3  and WT 1  to WT 5  are wires extending in the seat width direction and are disposed in a bridge shape between some of the plural vertical wires WH 1  to WH 4 . That is, the plural lower horizontal wires WD 1  to WD 3  have appropriate lengths, are disposed in a bridge shape between some of the lower parts of the first to fourth vertical wires WH 1  to WH 4 , and are connected thereto. For example, the lower horizontal wire WD 3  which is one of the plural lower horizontal wires crosses the first to fourth vertical wires WH 1  to WH 4  and are disposed in a region corresponding to the accommodating section  10 . In this embodiment, the lower horizontal wire WD 3  extrudes from the first vertical wire WH 1  to the seat inside so as to protrude into the accommodating section  10 . In addition, the plural upper horizontal wires WT 1  to WT 5  have appropriate lengths are disposed in a bridge shape between some of the upper parts of the first to fourth vertical wires WH 1  to WH 4 , and are connected thereto. Some (WT 2 , WT 4 , and WT 5 ) of the upper horizontal wires of the basic part  20 A and some (WT 2 , WT 4 , and WT 5 ) of the upper horizontal wires of the basic part  20 B are connected to each other by a wire-shaped junction JM in the upper part of the intermediate section  6   c.    
         [0024]    The bridging part  20 C is a part disposed over a pair of basic parts  20 A and  20 B and includes a first bridging wire WM 1  and a second bridging wire WM 2 . The first bridging wire WM 1  extends in the seat width direction above the lower horizontal wire WD 3 , is disposed to cross a pair of basic parts  20 A and  20 B, and is connected to the vertical wires.

The second bridging wire WM 2  has a short length and is disposed above the first bridging wire WM 1 . The second bridging wire WM 2  is disposed in a bridge shape between the first vertical wire WH 1  of the first seat back  6   a  and the first vertical wire WH 1  of the second seat back  6   b  and is connected thereto. 
         [0025]    As illustrated in  FIGS. 2 to 4 , the engaging portions (a first engaging portion  31 , a second engaging portion  32 , and a third engaging portion  33 ) are portions capable of engaging with appropriate positions of the floor console  40  (the installable component) to be described later and can be formed in the reinforcing member  20 . As illustrated in  FIG. 3 , the first engaging portion  31  according to this embodiment is formed of a ring-shaped wire having a substantially U shape in a front view and is attached to the first bridging wire WM 1  immediately above the accommodating section  10  in a state in which the seat back is upright. The first engaging portion  31  is disposed at the center of the accommodating section  10  in the seat width direction so as to protrude downward from the top side portion  10   a  of the accommodating section  10  into the accommodating section  10 . 
         [0026]    As illustrated in  FIG. 3 , the second engaging portion  32  can be formed by the lower horizontal wire WD 3  which is a part of the basic part  20 A. In this embodiment, the second engaging portion  32  can be formed by bending an end of the lower horizontal wire WD 3  extending in the seat width direction in a substantially lateral U shape. The second engaging portion  32  protrudes rightward from the first side portion  10   b  of the accommodating section  10  into the accommodating section  10 . The third engaging portion  33  can be formed by the lower horizontal wire WD 3  which is a part of the basic part  20 B. In this embodiment, the third engaging portion  33  can be formed by bending an end of the lower horizontal wire WD 3  extending in the seat width direction in a substantially lateral U shape. The third engaging portion  33  protrudes leftward from the second side portion  10   c  of the accommodating section  10  into the accommodating section  10 . In this embodiment, the second engaging portion  32  and the third engaging portion  33  are disposed to face each other and a clearance in which the floor console  40  to be described later can be disposed is formed therebetween. 
         [0027]    As illustrated in  FIG. 4 , the floor console  40  is a rectangular parallelepiped box member which is longer in the vehicle longitudinal direction and includes a top surface portion  40   a,  a first side surface portion  40   b,  a second side surface portion  40   c,  and plural engaged portions  51  to  53  to be described later (only a part of the floor console is illustrated in  FIG. 4  for the purpose of convenience). In this embodiment, the back part of the floor console  40  is disposed in the accommodating section  10  while positioning the floor console  40  in the front-back direction of the seat as will be described later. In this state, the floor console  40  is fixed to the vehicle floor surface using a fixing portion (not illustrated) formed on the bottom surface thereof. In this state, the top surface portion  40   a  of the floor console  40  is disposed to face the top side portion  10   a  of the accommodating section  10 . The first side surface portion  40   b  is disposed to face the first side portion  10   b  of the accommodating section  10  and the second side surface portion  40   c  is disposed to face the second side portion  10   c  of the accommodating section  10 . 
         [0028]    As illustrated in  FIG. 4 , the engaged portions (a first engaged portion  51 , a second engaged portion  52 , and a third engaged portion  53 ) are portions capable of engaging with the corresponding engaging portions  31  to  33 . The first engaged portion  51  is formed as a plate-like protruding piece protruding backward from the back end of the top surface portion  40   a  in a state in which the floor console  40  is disposed, and can be inserted into the ring-shaped first engaging portion  31  from the seating surface side. In this embodiment, the first engaged portion  51  is formed at the center of the top surface portion  40   a  and is disposed at a position which can be inserted into the first engaging portion  31 . The second engaged portion  52  is a depressed portion formed in the first side surface portion  40   b  and can engage with the second engaging portion  32  from the seat width direction. The third engaged portion  53  is a depressed portion formed in the second side surface portion  40   c  and can engage with the third engaging portion  33  from the seat width direction. The second engaged portion  52  and the third engaged portion  53  are opened on the back surface side of the floor console  40  and the corresponding engaging portions can be inserted thereinto from the front-back direction of the seat. 
         [0029]    As illustrated in  FIG. 4 , the pair of seat backs  6   a  and  6   b  and the floor console  40  are disposed at appropriate positions on the vehicle floor surface. The pair of seat backs  6   a  and  6   b  are fixed to the vehicle floor surface FL using the fixing member  9  in an upright state and then the floor console  40  is disposed in the accommodating section  10  and is fixed onto the vehicle floor surface. In this configuration, it is preferable that the floor console  40  be appropriately positioned and disposed in the accommodating section  10 . Accordingly, this embodiment employs a configuration in which the floor console  40  is positioned and disposed in the accommodating section  10  by causing the corresponding engaging portions  31  to  33  and the corresponding engaged portions  51  to  53  to engage with each other. 
         [0030]    That is, as illustrated in  FIG. 4 , the floor console  40  is inserted into the accommodating section  10  from the seating surface side and the first engaged portion  51  is inserted into the first engaging portion  31  protruding from the top of the accommodating section  10  from the seating surface side to engage with each other. By this engagement of the first engaging portion  31  and the first engaged portion  51 , the floor console  40  is disposed at the center of the accommodating section  10  and the relative movement thereof in the seat width direction is regulated. At the same time, the second engaging portion  32  is inserted into the second engaged portion  52  and then both engage with each other from the seat width direction. At the same time, the third engaging portion  33  is inserted into the third engaged portion  53  and then both engage with each other from the seat width direction. By this engagement of the second engaging portion  32  and the second engaged portion  52  (the third engaging portion  33  and the third engagement portion  53 ), the relative movement of the floor console  40  in the vertical direction is regulated and the rotation of the floor console  40  around an axis is appropriately prevented. In this way, in this embodiment, by the engagements of the engaging portions  31  to  33  and the engaged portions  51  to  53 , it is possible to appropriately regulate the movement of the floor console  40  in the vertical and horizontal directions relative to the accommodating section  10  and to position and dispose the floor console at appropriate positions in the accommodating section  10 . In this state, the floor console  40  is fixed onto the vehicle floor surface. Accordingly, referring to  FIGS. 1 to 4 , even when the positional relationship between the vehicle floor surface FL and the seat backs  6   a  and  6   b  (the accommodating section  10 ) varies, it is possible to dispose the floor console  40  at appropriate positions in the accommodating section  10  in an appropriate posture. 
         [0031]    As described above, in this embodiment, the engaging portions  31  to  33  can be stably formed in the reinforcing member  20  for reinforcing the seat pad  6 P. By the engagements of the engaging portions  31  to  33  and the engaged portions  51  to  53 , the floor console  40  can be appropriately positioned and disposed in the accommodating section  10 . In this embodiment, by inserting the first engaged portion  51  into the ring-shaped first engaging portion  31  from the seat surface side to engage with each other, it is possible to prevent the relative movement of the floor console  40  in the seat width direction. In addition, by causing the second engaging portion  32  (the third engaging portion  33 ) to engage with the second engaged portion  52  (the third engaged portion  53 ), it is possible to regulate the relative movement of the floor console  40  in the vertical direction. Accordingly, according to this embodiment, it is possible to appropriately position and dispose the floor console  40  in the accommodating section  10  of the seat backs  6   a  and  6   b.    
         [0032]    The reinforcing member, the engaging portions, and the engaged portions have various configurations other than the above-mentioned configuration. For example, in the modification example illustrated in  FIG. 5 , a plate-like reinforcing member  21  is attached to the back surface of the seat pad (not illustrated) and reinforces the seat pad. A pair of engaging portions  33   a  is parts which are formed by cutting out a part of the reinforcing member  21  in a substantially rectangular shape and protrudes inward from the side portions of the accommodating section  10  (only one engaging portion is illustrated in  FIG. 5  for the purpose of convenience). Accordingly, in this modification example, plate-like engaged portions  53   a  protruding in the seat width direction are formed on both side surface portions  41   c  of the floor console  41  (only one side surface portion and one engaged portion are illustrated in  FIG. 5  for the purpose of convenience). By inserting the engaged portions  53   a  into the engaging portions  33   a  to engage with each other, the floor console  41  is positioned and disposed in the accommodating section  10 . As a result, according to this modification example, the relative movement of the floor console  41  in the vertical direction can be regulated by causing the engaging portions  33   a  to engage with the engaged portions  53   a  in the seat width direction. 
         [0033]    The vehicle seat according to the embodiment is not limited to the above-mentioned embodiment, but may be modified in various forms. In the embodiment, the cutout-shaped accommodating section  10  is formed between a pair of seat backs  6   a  and  6   b,  but the configurations (the shape, the size, the formation position, and the number) of the accommodating section are not limited to this embodiment. For example, the accommodating section may be formed as a penetration hole penetrating the seat pad in the thickness direction of the seat pad or a non-penetration hole such as a recess having a depth in the thickness direction of the seat pad, as long as other installable component can be disposed therein. The accommodating section may be opened to the seating surface side, or may be opened to any appropriate surface of the seat back in consideration of the positional relationship with respect to the installable component. 
         [0034]    This embodiment describes an example in which plural engaging portions  31  to  33  and plural engaged portions  51  to  53  are formed, but the configurations (such as the shape, the size, the formation position, and the number) of the constituent portions are not particularly limited. For example, at least one of the first to third engaging portions may be disposed to protrude into the accommodating section. In this case, corresponding engaged portions can be formed in the installable component depending on the number of engaging portions formed. The engaging portions and the engaged portions may have various shapes or sizes so long as they can engage with each other. For example, an engaging portion having various shapes such as a substantially J shape (ring shape in which a cutout is formed in a part thereof) can be employed as the ring-shaped first engaging portion. When any one of the second engaging portion and the third engaging portion is formed, the relative movement of the installable component in the vertical direction can be properly regulated by causing one engaging portion to greatly protrude into the accommodating section. The second engaging portion and the third engaging portion may be formed to face each other or may be formed not to face each other. The engagement configuration of the second engaging portion and the second engaged portion (the third engaging portion and the third engaged portion) according to this embodiment may be employed as the engagement configuration of the first engaging portion and the first engaged portion. The engagement configuration of the first engaging portion and the first engaged portion according to this embodiment may be employed as the engagement configuration of the second engaging portion and the second engaged portion (the third engaging portion and the third engaged portion). The first to third engaging portions may be formed of the reinforcing member itself or may be formed by attaching another wire material or the like to the reinforcing member. 
         [0035]    In this embodiment, the floor console  40  is explained as an example of the installable component, but the type of the installable component is not limited. For example, a seat-configuring member such as an armrest and other seat installable components other than the seat back may be configured as the installable component. 
         [0036]    In this embodiment, an exemplary configuration of the vehicle seat  2  and the floor console  40  is described, but the configuration of these members can be appropriately modified. For example, the seat back may be connected to the seat cushion itself or the vehicle floor surface so as to be raised, lowered or in a upright state. The configuration of this embodiment can be applied to vehicle seats of a vehicle, an aircraft, an electric train, or the like. 
         [0037]    According to the present disclosure, the installable component can be appropriately positioned and disposed in the accommodating section of the seat back. According to the second and third aspects of the disclosure, the installable component can be more appropriately positioned and disposed in the accommodating section of the seat back.
