[0002] 2. Description of the Related Art Conventionally, there is known a vehicle seat that includes a seat back frame that constitutes the framework of the seat back, and a speaker attached to the seat back frame (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-092989 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, there is a demand for improved mounting rigidity for mounting members such as speakers that are attached to the frame of a seat.

[0005] Therefore, an object of the present invention is to provide a vehicle seat that can improve the mounting rigidity of a mounting member. Another object of the present invention is to provide a vehicle seat in which the mounting member can be easily fixed to the seat frame. [Means for solving the problem]

[0006] The vehicle seat may include a seat frame that forms a skeleton and an attachment member that is attached to the seat frame, wherein the seat frame has a first outer surface and a second outer surface that extends from an end of the first outer surface in a direction different from the first outer surface, and the attachment member may have a first fixing portion fixed to the first outer surface and a second fixing portion fixed to the second outer surface.

[0007] The seat frame has a first outer surface and a second outer surface extending in a direction different from the first outer surface, and the mounting member has a first fixing portion fixed to the first outer surface and a second fixing portion fixed to the second outer surface, thereby improving the mounting rigidity of the mounting member.

[0008] The first fixing portion and the second fixing portion may be provided at different positions in a direction in which a boundary portion between the first outer surface and the second outer surface extends.

[0009] By providing the first fixing portion and the second fixing portion at different positions in the extending direction of the boundary portion between the first outer surface and the second outer surface, the mounting rigidity of the mounting member can be further improved.

[0010] The first fixing portion may have a first through hole through which a fastening member for fixing the first fixing portion to the first outer surface passes, and the first through hole may be an elongated hole.

[0011] Since the first through hole for fixing the first fixing portion to the first outer surface is a long hole, any error in the position of the first through hole can be absorbed when fixing the mounting member to the seat frame, making it easier to fix the mounting member to the seat frame.

[0012] The mounting member may have a recess, and the first fixing portion may be provided at a bottom of the recess.

[0013] By providing the first fixing portion at the bottom of the recessed portion of the mounting member, the strength of the first fixing portion can be improved, and therefore the mounting rigidity of the mounting member can be further improved.

[0014] The seat frame may have a first engagement portion, and the mounting member may have a second engagement portion that engages with the first engagement portion in a state where the mounting member is fixed to the seat frame.

[0015] Since the seat frame has a first engagement portion and the mounting member has a second engagement portion, when fixing the mounting member to the seat frame, the first engagement portion and the second engagement portion can be engaged to temporarily fasten the mounting member to the seat frame, making it easy to fix the mounting member to the seat frame.

[0016] The second engagement portion may be provided adjacent to at least one of the first fixed portion and the second fixed portion.

[0017] By providing the second engagement portion adjacent to at least one of the first and second fixing portions, when the mounting member is temporarily fixed to the seat frame by the engagement between the first and second engagement portions, the positional accuracy between the fixing portion adjacent to the second engagement portion and the corresponding outer surface can be improved, making it easier to fix the mounting member to the seat frame.

[0018] The mounting member may include an electrical component and a bracket for mounting the electrical component to the seat frame, and the first fixing portion and the second fixing portion may be provided on the bracket.

[0019] The mounting member includes an electrical component and a bracket, and the first fixing portion and the second fixing portion are provided on the bracket, which makes it easy to mount the electrical component to the seat frame.

[0020] In addition, the vehicle seat may further include a clip for fastening a harness connected to the electrical component, and the bracket may have a plate-shaped main body having a clip attachment portion to which the clip is attached, a bead protruding from the main body, and a flange rising from an edge of the main body, and the clip attachment portion may be provided between the bead and the flange.

[0021] By providing the clip attachment portion between the bead and the flange, the strength of the clip attachment portion can be improved, and therefore the attachment strength of the clip can be improved.

[0022] The vehicle seat may further include a connector connected to the electrical component, and the bracket may have a plate-shaped main body having a second through hole formed at a position opposite the connector, and a first bead and a second bead protruding from the main body, and the second through hole may be provided between the first bead and the second bead.

[0023] The bracket has a second through hole formed at a position facing the connector, so that the connection state of the connector can be confirmed through the second through hole. In addition, the second through hole is provided between the first bead and the second bead, so that the strength of the bracket near the second through hole can be ensured.

[0024] The seat frame may include a side frame constituting a left or right frame, and the first outer surface and the second outer surface may be located on the side frame.

[0025] The vehicle seat may include a seat cushion and a seat back, the seat frame including a seat cushion frame that forms the skeleton of the seat cushion and a seat back frame that forms the skeleton of the seat back, the seat cushion including the seat cushion frame, a seat cushion pad that covers the seat cushion frame, and a seat cushion skin that covers the seat cushion frame and the seat cushion pad, and the seat back including the seat back frame, a seat back pad that covers the seat back frame, and a seat back skin that covers the seat back frame and the seat back pad. Effect of the Invention

[0026] The seat frame has a first outer surface and a second outer surface extending in a direction different from the first outer surface, and the mounting member has a first fixing portion fixed to the first outer surface and a second fixing portion fixed to the second outer surface, thereby improving the mounting rigidity of the mounting member.

[0027] Furthermore, by providing the first fixing portion and the second fixing portion at different positions in the extending direction of the boundary portion between the first outer surface and the second outer surface, the mounting rigidity of the mounting member can be further improved.

[0028] Furthermore, since the first through hole for fixing the first fixing portion to the first outer surface is a long hole, any error in the position of the first through hole can be absorbed when fixing the mounting member to the seat frame, making it easier to fix the mounting member to the seat frame.

[0029] Furthermore, by providing the first fixing portion at the bottom of the recessed portion of the mounting member, the strength of the first fixing portion can be improved, and therefore the mounting rigidity of the mounting member can be further improved.

[0030] Furthermore, since the seat frame has a first engagement portion and the mounting member has a second engagement portion, when fixing the mounting member to the seat frame, the first engagement portion and the second engagement portion can be engaged to temporarily fasten the mounting member to the seat frame, making it easy to fix the mounting member to the seat frame.

[0031] Furthermore, by providing the second engagement portion adjacent to at least one of the first and second fixing portions, when the mounting member is temporarily fixed to the seat frame by the engagement between the first and second engagement portions, the positional accuracy between the fixing portion adjacent to the second engagement portion and the corresponding outer surface can be improved, making it easier to fix the mounting member to the seat frame.

[0032] Furthermore, since the mounting member includes the electrical component and the bracket, and the first fixing portion and the second fixing portion are provided on the bracket, it is easy to mount the electrical component to the seat frame.

[0033] Furthermore, by providing the clip attachment portion between the bead and the flange, the strength of the clip attachment portion can be improved, thereby improving the attachment strength of the clip.

[0034] In addition, since the bracket has a second through hole formed at a position facing the connector, the connection state of the connector can be confirmed through the second through hole. And, since the second through hole is provided between the first bead and the second bead, the strength of the bracket near the second through hole can be ensured.

[0077] Furthermore, since the first fixing portion 111 and the second fixing portion 121 are provided at different positions in the extension direction of the boundary portion BD between the first outer surface 221 and the second outer surface 222, the mounting rigidity of the mounting member 30 can be further improved compared to when the first fixing portion and the second fixing portion are provided at the same position in the extension direction of the boundary portion BD.

[0078] Furthermore, since the first through hole 111A for fixing the first fixing portion 111 to the first outer surface 221 is a long hole, any error in the position of the first through hole 111A can be absorbed when fixing the mounting member 30 to the seat frame F, making it easier to fix the mounting member 30 to the seat frame F.

[0079] Furthermore, by providing first fixing portion 111 at the bottom of recess 116 of mounting member 30, the strength of first fixing portion 111 can be improved, and therefore the mounting rigidity of mounting member 30 can be further improved.

[0080] Furthermore, since the seat frame F has the engagement holes 225 and the mounting member 30 has the engagement claws 122, when fixing the mounting member 30 to the seat frame F, the engagement holes 225 and the engagement claws 122 can be engaged with each other to temporarily fasten the mounting member 30 to the seat frame F. This makes it easy to fix the mounting member 30 to the seat frame F.

[0081] Furthermore, by providing the engagement claws 122 adjacent to the second fixing portions 121, when the mounting member 30 is temporarily fixed to the seat frame F by engagement between the engagement holes 225 and the engagement claws 122, it is possible to improve the positional accuracy between the second fixing portions 121 adjacent to the engagement claws 122 and the corresponding second outer surfaces 222. This makes it easier to fix the mounting member 30 to the seat frame F.

[0082] Furthermore, since the mounting member 30 includes the switch 300 and the bracket 100, and the first fixing portion 111 and the second fixing portion 121 are provided on the bracket 100, the switch 300 can be easily mounted on the seat frame F.

[0083] Furthermore, the bracket 100 has the main body flange 130 and the extension flange 140, thereby improving the strength of the bracket 100. This allows the mounting rigidity of the mounting member 30 to be further improved.

[0084] In addition, since the clip mounting portion 112 is provided between the second bead 152 and the lower flange 133 of the main body flange 130, the strength of the clip mounting portion 112 can be improved, and therefore the mounting strength of the clip 41 can be improved.

[0085] In addition, since the clip mounting portion 112 is provided between the front flange 132 of the main body flange 130 and the recess 116, the strength of the clip mounting portion 112 can be improved, and therefore the mounting strength of the clip 41 can be improved.

[0086] Furthermore, since the bracket 100 has the second through hole 113 formed at a position facing the first connector 43, the connection state between the first connector 43 and the second connector 311 of the switch 300 can be confirmed from the left and right inner sides through the second through hole 113 (see FIG. 6(b)). Furthermore, since the second through hole 113 is provided between the first bead 151 and the second bead 152, the strength of the bracket 100 in the vicinity of the second through hole 113 can be ensured.

[0087] In addition, since only the central portion in the vertical direction having the second fixing portion 121 of the extension portion 120 of the bracket 100 extends to the inside on the left and right sides, the bracket 100 can be made more compact and lightweight than in the case where the entire extension portion extends to the inside on the left and right sides.

[0088] In addition, by fixing the second fixing portion 121 located above to the rear surface of the seatback side frame 21, the load-bearing capacity can be improved when force is applied to the upper part of the mounting member 30 from the front and rear.

[0089] Although the embodiment has been described above, the vehicle seat can be modified as appropriate as exemplified below.

[0090] In the embodiment, the engaging claw 122 as the second engaging portion is provided adjacent to the second fixed portion 121, but for example, the second engaging portion may be provided adjacent to the first fixed portion instead of the second fixed portion. Also, the second engaging portion may be provided adjacent to both the first fixed portion and the second fixed portion.

[0091] In the above embodiment, the engagement hole 225 is exemplified as the first engagement portion, and the engagement claw 122 (a convex portion that engages with the hole) is exemplified as the second engagement portion, but for example, the first engagement portion may be a convex portion and the second engagement portion may be a hole. Also, one of the first engagement portion and the second engagement portion may be a bottomed hole (concave portion) instead of a through hole. Also, the vehicle seat may be configured without the first engagement portion and the second engagement portion.

[0092] In the above embodiment, the first fixing portion 111 is provided at the bottom of the recess 116 of the bracket 100 (mounting member 30), but for example, the first fixing portion may be provided at a portion other than the recess of the mounting member. In other words, the mounting member may be configured not to have a recess in which the first fixing portion is provided. Also, the second fixing portion may be provided at the bottom of the recess of the mounting member.

[0093] In the embodiment, the first through hole 111A of the first fixing portion 111 is an elongated hole, but for example, the first through hole may be a substantially circular hole. In this case, the circular first through hole may be a hole with a larger diameter than a circular through hole (see first through hole 223) formed in the seat frame and through which a fastening member passes.

[0094] In the above embodiment, the first fixing portion 111 and the second fixing portion 121 are provided at different positions in the direction in which the boundary BD extends, but for example, the first fixing portion and the second fixing portion may be provided so as to overlap in the direction in which the boundary between the first outer surface and the second outer surface extends. Furthermore, the first fixing portion and the second fixing portion may be provided at the same position in the direction in which the boundary between the first outer surface and the second outer surface extends.

[0095] In the above embodiment, the bracket 100 has the clip attachment portion 112 to which the clip 41 is attached, but for example, the bracket may have a configuration that does not include a clip attachment portion. In other words, the harness connected to the electrical component does not have to be fastened to the bracket.

[0096] In the above embodiment, the main body 110 of the bracket 100 has the second through hole 113, but for example, the bracket may have a configuration in which the second through hole is not formed.

[0097] In the above embodiment, the fixing parts 111, 121 are fixed to the outer surfaces 221, 222 by the rivets 91, 92, but the fixing parts may be fixed to the outer surfaces by, for example, bolts and nuts. In other words, the fastening members may be bolts and nuts instead of rivets. In this case, one of the bolt and the nut may be welded to the seat frame. Also, the fixing parts may be fixed to the outer surfaces by, for example, welding.

[0098] In the above embodiment, the switch 300 is exemplified as an electrical component, but the electrical component may be, for example, a speaker or a liquid crystal panel. In addition, in the above embodiment, the mounting member 30 includes the switch 300 (electrical component) and the bracket 100, but, for example, the mounting member may not include a bracket. In this case, the first fixing portion and the second fixing portion may be provided on the electrical component. In other words, the electrical component may be directly attached to the seat frame without a bracket.

[0099] In the above embodiment, the first outer surface 221 and the second outer surface 222 are located on the right frame (right seatback side frame 21) of the seatback S2, but for example, the first outer surface and the second outer surface may be located on the left frame of the seatback. Also, the first outer surface and the second outer surface may be located on the frame above the seatback or on the frame below the seatback. Also, the first outer surface and the second outer surface may be located on the seat cushion frame.

[0100] In other words, in the above embodiment, the mounting member 30 is attached to the right frame of the seat back S2, but for example, the mounting member may be attached to the left frame of the seat back. Also, the mounting member may be attached to the upper frame of the seat back or the lower frame of the seat back. Also, the mounting member may be attached to the left or right frame of the seat cushion, or the front or rear frame of the seat cushion.

[0101] In the above embodiment, the vehicle seat S mounted on an automobile is exemplified as the vehicle seat, but for example, the vehicle seat may be a seat mounted on a railroad car, etc. Also, the vehicle seat may be a seat mounted on a vehicle other than a car, for example, an airplane, a ship, etc.

[0102] The elements described in the above embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
