Description

Technical Field

[0001] This invention relates to a vehicle seat equipped with electrical components. Background Technology

[0002] In recent years, vehicle seats that integrate various electrical components have been known to improve convenience and comfort when seated. Such vehicle seats are illustrated, for example, in Japanese Patent Application Publication No. 2008-092989A. In the vehicle seat described in JP2008-092989A, a speaker system is installed in the seat back that supports the back of the occupant, outputting sound from behind the occupant towards them.

[0003] Furthermore, in order to further improve the convenience or comfort of sitting, the number of electrical components installed in the seat increases, as does the number of wiring connected to each electrical component. When the number of wiring increases, it becomes difficult to configure the wiring to suppress bending loads, which are easily acted upon by bending loads and other factors within the wiring housed inside the seat. Summary of the Invention

[0004] An embodiment of the vehicle seat of the present invention includes: a frame portion and an electrical component mounted on the frame portion. The frame portion has: a frame body; and a reinforcing portion for reinforcing the frame body. The electrical component has: an electrical component body; and a wiring portion connected to the electrical component body. At least a portion of the electrical component body is mounted in a manner that overlaps with the frame body and the reinforcing portion in a frontal view. The wiring portion is supported on the reinforcing portion. Attached Figure Description

[0131] The following is for reference Figures 1 to 11BAn embodiment of the present invention will be described. The vehicle seat of this embodiment is a seat in which the garnish and speaker system (electrical components) are integrally mounted on the seat back, and can be used in various vehicles such as airplanes, railways, ships, and automobiles. Hereinafter, as an example of a vehicle seat, a seat mounted in an automobile, particularly a rear seat constituting the rear seat of an automobile (hereinafter referred to as "seat"), will be used for description. Furthermore, the structure of each part will be described below based on the occupant (seat user) in the seat, defining the front-to-back direction, left-to-right direction (width direction), and vertical direction (height direction).

[0132] Figure 1 This is a front view of a vehicle seat 1 according to an embodiment of the present invention. Figure 1 The description only covers the right-side seat (right side) of the rear seats, which can seat three people, omitting the description of the center seat (center side) and the left-side seat (left side). Therefore, the right-side seat of the rear seats will be described below as seat 1. Figure 1 As shown, seat 1 includes: seat cushion 2, which supports the occupant's buttocks; seat back 3, which supports the occupant's upper body (waist and back); and headrest 4, which supports the occupant's head.

[0133] The seat cushion 2 is constructed such that a seat cushion pad 21 containing a cushioning material such as urethane foam is installed on the seat cushion frame 20, which forms the skeleton, and then the outer side of the pad is covered with a surface material 22 containing synthetic leather or fabric. The seat cushion 2 is supported in a sliding manner in the front-to-back direction by means of a sliding mechanism (not shown) provided on the floor of the vehicle.

[0134] The seat back 3 is constructed such that a seat back pad 31 containing a cushioning material such as urethane foam is installed on the seat back frame (frame portion) 30 that forms the skeleton, and then the outer side of the pad is covered with a surface material 32 containing synthetic leather or fabric. The seat back 3 is rotatably supported on the seat cushion 2 by a tilting mechanism (not shown).

[0135] The seat backrest 3 includes: decorative elements 5 disposed on the shoulders of the seated occupant; and a speaker system 6 mounted inside the seat backrest 3 facing the decorative elements 5. The decorative elements 5 constitute the speaker grille of the speaker system 6. The speaker system 6 outputs sound from near the shoulders of the seated occupant via the decorative elements 5. The specific structure of the seat backrest 3 with the decorative elements 5 and the speaker system 6 will be described in detail later.

[0136] The headrest 4 does not have a frame forming a skeleton like the seat cushion 2 or the seat back 3. Instead, it is constructed by filling the interior of a surface material (headrest body) 42, which includes synthetic leather or fabric, with a cushioning pad (headrest body) containing a cushioning material such as urethane foam, and then placing a headrest post 40 therein. The headrest 4 is configured to be held above the seat back 3 via the headrest post 40, and in this held state, at least a portion overlaps with the trim piece 5. In other words, the headrest 4 is configured such that at least a portion of it overlaps with a portion of the speaker system 6 in a frontal view.

[0137] The headrest pillar 40 has a pair of legs 40a formed by bending a metal rod-shaped member and held in place on the seat back frame 30 (see reference). Figure 3 The headrest column 40 is held and protected by the front headrest cover 43 and the rear headrest cover 44, which engage and lock together in the front-to-back direction (see reference). Figure 2 ).

[0138] Figure 2 This is a perspective view of seat 1 with the outer leather material 32, seat back cushion 31, and decorative parts 5 removed from the seat back 3. Figure 3 This is an exploded perspective view of the seat 1 with the outer cover material 32 and seat back cushion 31 removed from the seat back 3.

[0139] like Figure 2 , Figure 3 As shown, the seat back 3 includes: a metal seat back frame 30 forming the skeleton of the seat back 3; a synthetic resin front panel 33 disposed on the front surface of the seat back frame 30; a synthetic resin back panel 34 disposed on the back of the seat back frame 30; a synthetic resin rear cover 35 disposed above the seat back frame 30 and the back panel 34; a seat belt retractor 36 housing the seat belt; a trim piece 5 mounted on the seat back frame 30; and a speaker system 6 mounted on the seat back frame 30 facing the trim piece 5.

[0167] Figure 8A This is a three-dimensional view of the interior trim piece 52 as seen from the front. Figure 8B This is a three-dimensional view taken from the rear. For example... Figure 8A , Figure 8B As shown, the interior trim piece 52 has a shape substantially the same as the grille guide piece 51, and is engaged with the grille guide piece 51. Specifically, the interior trim piece 52 has an inner body 521 extending in the left-right direction and having a shape substantially the same as the guide body 511, and a frame portion 522 provided on the outer edge of the inner body 521. The inner body 521 has a front surface 521F and a rear surface 521R, and a pair of left and right openings 523 provided on both sides in the left-right direction. The openings 523 face the honeycomb portion 513 of the guide body 511 and face the speaker unit 62 of the speaker system 6.

[0168] The inner body 521 is provided with a plurality of through holes 524 through which a plurality of protrusions 515 of the guide body 511 pass. Specifically, the plurality of through holes 524 have: a pair of first through holes 524a through which a pair of first protrusions 515a of the guide body 511 pass; a pair of second through holes 524b through which a pair of second protrusions 515b pass; a pair of third through holes 524c through which a pair of third protrusions 515c pass; and a pair of fourth through holes 524d through which a pair of fourth protrusions 515d pass. When the grille guide 51 and the inner trim 52 are facing each other, the locking claws 516 of the first protrusion 515a, the second protrusion 515b, the third protrusion 515c and the fourth protrusion 515d of the guide body 511 pass through the first through hole 524a, the second through hole 524b, the third through hole 524c and the fourth through hole 524d and lock onto the rear surface 521R of the inner body 521.

[0169] On the rear surface 521R of the inner body 521, a plurality of concave portions (first concave portions) 525 are provided at positions corresponding to the plurality of through holes 524, which are concave when viewed from the vertical or horizontal direction. The plurality of concave portions 525 have: a pair of first concave portions 525a, provided at positions corresponding to a pair of first through holes 524a; a pair of second concave portions 525b, provided at positions corresponding to a pair of second through holes 524b; and a pair of third concave portions 525c, provided at positions corresponding to a pair of third through holes 524c.

[0170] The first concave portion 525a, the second concave portion 525b, and the third concave portion 525c each have: a bottom (first bottom) 526 of the rear surface 521R, a vertical wall portion (first vertical wall portion) protruding rearward from the bottom 526, and an extension portion (first extension portion) 528 extending approximately at a right angle from the vertical wall portion 527. A pair of left and right line portions 81R and 81L of the decorative element mounting portion 8 are respectively arranged in the space surrounded by the bottom 526, the vertical wall portion 527, and the extension portion 528 of the pair of first concave portions 525a. Specifically, the upper line 84 of each of the left and right line portions 81R and 81L is arranged in the space surrounded by the bottom 526, the vertical wall portion 527, and the extension portion 528 of the pair of second concave portions 525b. The side line 85 of the left and right line portions 81R and 81L is arranged in the space surrounded by the bottom 526, the vertical wall portion 527, and the extension portion 528 of the pair of second concave portions 525b. In the space surrounded by the bottom 526 of a pair of third concave portions 525c, the vertical wall portion 527 and the extension portion 528, the lower line 86 of a pair of left and right line portions 81R and 81L is arranged.

[0171] A recessed clearance portion 529, recessed along the thickness direction, is provided at the bottom 526 of each of the pair of first concave portions 525a, second concave portions 525b, and third concave portions 525c. This allows for easy guidance of the left and right pair of line portions 81R and 81L to the pair of first concave portions 525a, second concave portions 525b, and third concave portions 525c, respectively. The front end of the extension portion 528 of each of the pair of first concave portions 525a, second concave portions 525b, and third concave portions 525c is formed to elastically deform in a direction away from the bottom 526. This further facilitates easier guidance of the left and right pair of line portions 81R and 81L to the pair of first concave portions 525a, second concave portions 525b, and third concave portions 525c, respectively.

[0172] Figure 9 This is a front view showing the structure of the speaker system 6 fixed to the seat back frame 30. (See diagram below.) Figure 9 As shown, the loudspeaker system 6 has a pair of left and right loudspeaker systems 6R and 6L with the same structure. The left and right loudspeaker systems 6R and 6L each have a loudspeaker device (electric component body) 60 and a wiring section 61 connected to the loudspeaker device 60.

[0173] The loudspeaker assembly 60 includes: a loudspeaker unit 62 for outputting sound; a loudspeaker enclosure 63 for supporting the loudspeaker unit 62; and a rear housing 64 for securing the loudspeaker enclosure 63 to the seat back frame 30. Although detailed descriptions are omitted, the loudspeaker unit 62 is generally conical. The loudspeaker enclosure 63 supports the loudspeaker unit 62 with the honeycomb portion 513 of the guide body 511 and the opening 523 of the inner body 521 facing each other, and is concave in a rearward and downward recessed manner from the support portion of the loudspeaker unit 62 (see reference). Figure 11A Therefore, the speaker box 63 can be configured without compromising the seating comfort of the occupants.

[0174] The left and right pairs of rear housings 64 each have: a housing body 641, which is engaged with the rear surface of the speaker box 63; a first extension 642, which extends upward from the upper end of the housing body 641 in the left-right direction, approximately in the center; and a pair of left and right second extensions 643, which extend downward from the lower ends of the housing body 641 in the left-right direction.

[0175] Figure 10A This is a plan view of the first extension 642 of the rear housing 64 as viewed from above. Figure 10B yes Figure 10A An enlarged view of the first extension 642. (See image below.) Figure 9 , Figure 10A , Figure 10B As shown, the first extension 642 has a first fixing part 642a. A through hole is provided in the first fixing part 642a.

[0176] The first fixing part 642a and the fixing part 70a provided in the main body 70 of the retaining part of the headrest retaining part 7 ( Figure 5 The headrest retaining part 7 is provided with a pair of left and right column guides 73 on the front surface of the retaining part body 70 of the headrest retaining part 7. Figure 5 Therefore, the rear housing 64 is fixed to the headrest retainer 7 via a first fixing portion 642a of a first extension 642 located at approximately the same position in the vertical direction as the left and right pair of pillar guide portions 73.

[0177] Each of the left and right second extensions 643 has a second fixing part 643a. A through hole is provided in the second fixing part 643a. The pair of second fixing parts 643a and the fixing part 38g1 of the pair of sixth extensions 38g provided on the reinforcing plate 38 ( Figure 4 The rear housing 64 is arranged facing each other. The lower end of the rear housing 64 is fixed to the frame body 37 and the reinforcing plate 38 via the second fixing part 643a of a pair of second extensions 643. In other words, the lower end of the rear housing 64 is overlapped and fixed at the position where the frame body 37 and the reinforcing plate 38 overlap.

[0178] Wiring section 61 connects to speaker unit 62 and an amplifier (not shown). Audio signals output from the amplifier are input to speaker unit 62 via wiring section 61. Figure 9 As shown, the wiring section 61 extends from the lower part of the seat back 3 upward and is fixed to the seat back frame 30 at multiple locations via clamps 65.

[0179] The wiring section 61 is supported by reinforcing plates 38 at multiple locations. Specifically, the wiring section 61 is supported by clamps 65 to extend vertically along the first extension 38b, the second extension 38c, and the third extension 38d of the reinforcing plate 38. The first extension 38b and the fourth extension 38e are positioned at approximately the same location in the vertical direction. Figure 4 The wiring section 61 is supported at the same or nearly the same position in the vertical direction at the junction 38e1 with the fourth extension 38e.

[0180] The wiring section 61 is supported by a clamp 65 to extend in the left-right direction at the fifth extension 38f of the reinforcing plate 38. The fifth extension 38f is located higher than the fourth extension 38e. Figure 4 Therefore, the support portion 38f1 of the fifth extension 38f is disposed between the joint portion 38e1 of the fourth extension 38e and the speaker device 60. Figure 4 As shown, the joint portion 38e1 of the fourth extension portion 38e is disposed between the support portion 38d1 of the third extension portion 38d and the support portion 38f1 of the fifth extension portion 38f in the vertical direction, and is disposed between the support portion 38b1 of the first extension portion 38b and the support portion 38d1 of the third extension portion 38d in the horizontal direction.

[0181] Thus, the wiring section 61 is supported by the third extension 38d, extending vertically to the right of the reinforcing plate 38; by the fifth extension 38f, extending horizontally above the reinforcing plate 38; and by the second extension 38c, extending vertically to the left of the reinforcing plate 38. The wiring section 61 is supported at different vertical positions by the extensions 38d, 38f, and 38c. Furthermore, the wiring section 61 branches into two strands to the left of the second extension 38c. A pair of wiring sections 61L and 61R extend upwards toward the respective speaker units 62 of the left and right speaker systems 6R and 6L, and connect to the speaker units 62. One of the wiring sections 61 connected to the speaker unit 62 of the speaker system 6R is supported by the first extension 38b.

[0182] The seat backrest 3, as described above, is manufactured in the following manner. First, reinforcing plates 38 and 39 are joined to the frame body 37 by welding or the like. Figure 2 , Figure 9 Subsequently, the decorative part mounting part 8 and the headrest retaining part 7 are fixed to the frame body 37 using bolts and nuts 11, and then joined by welding. Figure 5 Thus, the seat back frame 30 is formed.

[0183] Next, the speaker system 6 is installed on the seat back frame 30. First, the lower end of the speaker unit 60 is brought into contact with the abutment portion 38h1 formed near the rib 38h of the reinforcing plate 38. Figure 4 Positioning is achieved by contact. Then, the fixing portion 38g1 of the pair of sixth extensions 38g of the reinforcing plate 38 ( Figure 4 The pair of second extensions 643 of the housing 64 are secured with bolts 10 and nuts. Figure 9 Thus, the speaker unit 60 is mounted on the seat back frame 30 in a manner that overlaps with the reinforcing plate 38 in the front-back direction.

[0184] Subsequently, in the fixing part 70a of the retaining part main body 70 of the headrest retaining part 7 ( Figure 5 The first extension 642 of the housing 64 is secured with bolts and nuts. Figure 9 Thus, the first extension 642 of the rear housing 64 is fixed between the left and right pairs of second extensions 643 of the rear housing 64.

[0185] Subsequently, interior trim pieces 52 are installed on the left and right pairs of lines 81R and 81L of the trim piece mounting section 8. Specifically, the space surrounded by the bottom 526, the vertical wall 527, and the extension 528 of the plurality of recessed portions 525 of the interior trim piece 52 is ( Figure 8B The vertical wall portion 527 and the extension portion 528 are bent to engage the left and right pair of line portions 81R and 81L of the decorative element mounting portion 8. A relief portion 529 is provided at the bottom 526 of the plurality of recessed portions 525 of the inner decorative element 52, and the front end of the extension portion 528 is formed to bend away from the bottom 526. Thus, the left and right pair of line portions 81R and 81L can be easily engaged with the first recessed portion 525a, the second recessed portion 525b, and the third recessed portion 525c.

[0186] Subsequently, grille guide 51 and mounting grille 50 are installed on the interior trim piece 52. Figure 11A This is a cross-sectional view showing the intermediate state of the installation of the grille guide 51 and the mounting grille 50 on the interior trim piece 52. Figure 11B This is a cross-sectional view showing the state of the grille guide 51 and the mounting grille 50 after they are installed on the interior trim 52.

[0187] like Figure 11A , Figure 11BAs shown, firstly, a pair of protrusions 515 formed on the rear surface 511R of the guide body 511 of the grille guide 51 are inserted into a pair of through holes 524 formed on the inner body 521 of the inner trim 52. This causes the grille guide 51 to be engaged with the inner trim 52. At this time, the protrusions 515 of the grille guide 51 face the concave portion 525 of the inner trim 52, and the upper line 84, side line 85, and lower line 86 of the left and right line portions 81R and 81L are arranged to be surrounded by the concave portion 525 and the protrusions 515. The protrusions 515 are formed such that they separate from the extension 528 when the grille guide 51 is engaged with the inner trim 52, thereby suppressing any abnormal noise caused by contact between the protrusions 515 and the extension 528.

[0188] Then, the multiple protrusions 503 of the mounting grille 50 are inserted into the multiple through holes 517 of the grille guide 51. Figure 7A The mounting grille 50 is then engaged with the grille guide 51. At this time, the front ends of the plurality of protrusions 503 of the mounting grille 50 are located between the rear surface of the grille guide 51 and the front surface of the inner trim 52. In addition, since a grid-like rib 514 is provided on the front surface 511F of the guide body 511 of the grille guide 51, Figure 7A Therefore, the grille body 501 and the guide body 511 abut against each other through the partition rib 514.

[0189] Subsequently, the spacer retractor protector 36a is used to install the seat belt retractor 36 onto the seat back frame 30. Figure 3 Then, the remaining parts, such as the front panel 33, back panel 34, and rear cover 35, are installed on the seat back frame 30. Finally, the seat back cushion 31 is installed on the seat back frame 30, and then covered with a leather material 32, thereby forming the seat back 3. Figure 1 ).

[0190] According to this embodiment, the following effects can be achieved.

[0191] (1) The seat 1 of this embodiment includes: a seat back frame 30 and a speaker system 6, which is installed on the seat back frame 30. Figure 1 The seat back frame 30 includes: a frame body 37; and a reinforcing plate 38 for reinforcing the frame body 37. Figure 2 The loudspeaker system 6 includes: a loudspeaker assembly 60; and a wiring section 61 connected to the loudspeaker assembly 60. Figure 2 At least a portion of the loudspeaker assembly 60 is mounted in a manner that overlaps with the frame body 37 and the reinforcing plate 38 in the front-to-back direction, i.e., from a frontal view. The wiring section 61 is supported on the reinforcing plate 38. Figure 2 ).

[0192] According to the structure described above, the wiring section 61 can be arranged in the part of the frame body 37 where the rigidity is increased by the reinforcing plate 38. Therefore, deformation of the wiring section 61 caused by bending loads can be suppressed. In addition, a support portion for supporting the wiring section 61 can be provided in the part where the frame body 37 overlaps with the reinforcing plate 38, so that the wiring section 61 can be firmly supported without reducing the rigidity of the frame body 37.

[0193] (2) The reinforcing plate 38 is joined to the frame body 37. Figure 2 The wiring section 61 is supported on the reinforcing plate 38 at the same position in the vertical direction as the joint 38e1 between the reinforcing plate 38 and the frame body 37. Figure 9 The structure allows for support of the wiring section 61 in areas with higher rigidity.

[0194] (3) The wiring section 61 is supported by multiple support sections 38b1, 38c1, 38d1, and 38f1 provided on the reinforcing plate 38. Figure 4 , Figure 9 Therefore, the reinforcing plate 38 can not only function as a reinforcing part, but also as a supporting part to support the wiring part 61.

[0195] (4) The wiring section 61 is supported such that it extends in a generally vertical direction (first direction) via support sections 38b1, 38c1, and 38d1, and is also supported such that it extends in a generally horizontal direction (second direction) via support section 38f1. Figure 4 , Figure 9 As a result, the wiring section 61 extends in multiple directions, making the wiring section 61 easy to handle and avoiding interference between multiple wiring sections 61.

[0196] (5) The reinforcing plate 38 has: a central plate portion 38a (first plate portion) extending in the vertical and horizontal directions; a fifth extension portion 38f (second plate portion) extending from the right end of the central plate portion 38a along the central plate portion 38a; and a first extension portion 38b, a second extension portion 38c and a third extension portion 38d (third plate portion) extending rearward from the left and right ends of the central plate portion 38a. Figure 4 Multiple support portions 38b1, 38c1, 38d1, and 38f1 are provided in the first extension portion 38b, the second extension portion 38c, the third extension portion 38d, and the fifth extension portion 38f. Figure 4 Therefore, the support position of the wiring section 61 can be clearly defined, and it can be prevented from supporting the wiring section 61 in the wrong place.

[0197] (6) The support part 38f1 is positioned differently in the vertical direction from the other support parts 38b1, 38c1, and 38d1. Figure 4 Therefore, the wiring section 61 can be well supported in multiple different positions in the vertical direction.

[0198] (7) The loudspeaker device 60 is mounted on the front surface of the frame body 37. Figure 9 The reinforcing plate 38 is joined to the front surface of the frame body 37 via multiple joints 38a1, with the front end of the reinforcing plate 38 located further rearward than the front end of the speaker assembly 60. Figure 9 The support portion 38f1 supports the wiring portion 61 so that the wiring portion 61 extends in the left-right direction, and is located below the speaker device 60 and above the lower of the plurality of joint portions 38a1. Figure 9 With this structure, the wiring section 61 is supported above the joint 38a1, which is located further rearward and lower than the front end of the speaker device 60, thus suppressing excessive pressure on the wiring section 61 due to loads from the front.

[0199] (8) The plurality of support parts include: support part 38b1 and support part 38c1, which are disposed on the left side of the reinforcing plate 38 and support the wiring part 61 in a state of extending in the vertical direction; and support part 38d1, which is disposed on the right side of the reinforcing plate 38 and supports the wiring part 61 in a state of extending in the vertical direction. Figure 4 One of the two joints 38a1 is disposed vertically between the support portion 38f1 and one of the support portions 38b1, 38c1, or 38d1, and horizontally between the support portions 38b1, 38c1, and 38d1. This improves the workability of installing the wiring section 61.

[0200] (9) The support portion includes: a support portion 38c1 (first end side first support portion), disposed at the left end (first end) of the reinforcing plate 38; and a support portion 38d1 (second end side first support portion), disposed at the right end (second end) of the reinforcing plate 38. Figure 4 The support part 38f1 is positioned above the support part 38d1. Figure 4 The wiring section 61 is supported such that it extends vertically via support sections 38c1 and 38d1, and horizontally via support section 38f1. Figure 9 Therefore, the wiring section 61 can be configured with a gentle curvature.

[0201] (10) The wiring section 61 extends to the left and below the support section 38c1 in the left-right direction and branches into two strands. The pair of wiring sections 61L and 61R that are branched out extend upwards. Figure 9 This allows the wiring section to bend gently while branching into two strands for configuration.

[0202] (11) The loudspeaker assembly 60 includes: a loudspeaker assembly 60R (first electrical component body), disposed above the reinforcing plate 38 and at the same position as the reinforcing plate 38 in the left-right direction; and a loudspeaker assembly 60L (second electrical component body), disposed to the left of the loudspeaker assembly 60. Figure 9 A pair of wiring sections 61L and 61R are respectively connected to the left and right speaker units 60R and 60L. Figure 9 Therefore, the wiring section 61 can be easily connected to the multiple speaker units 60L and 60R above the reinforcing plate 38.

[0203] The implementation method can be modified into various forms. Figure 12A , Figure 12B This is a diagram showing a modified example of the wiring section 61 of the loudspeaker system 6. Figure 12A This is a three-dimensional view taken from the front and slightly above the seat back 3. Figure 12B This is a frontal view. Figure 12A , Figure 12B In the example shown, the length of one of the wiring portions 61 branching into two strands from the left side of the second extension 38c is different from the length of the other. That is, one wiring portion 61R that connects to the speaker unit 62 of the speaker system 6R from the branch 61a is longer than the other wiring portion 61L that connects to the speaker unit 62 of the speaker system 6L. In this way, by making the lengths of one and the other wiring portions 61L and 61R that branch into two strands different from each other, it is possible to prevent the wiring portions 61 from being mistakenly installed on the speaker units 62 of each of the left and right speaker systems 6R and 6L.

[0204] In the described embodiment, a speaker unit is used as an electrical component, but electrical components are not limited to this. For example, other devices that can improve the convenience or comfort of passengers, such as massage devices built into the seat or microphone devices that use sound input to give instructions to various devices in the vehicle, may also be used as electrical components.

[0205] In the described embodiment, the rear seat of a car was used as a vehicle seat, but the vehicle seat is not limited to this.
