Description

[Technical Field]

[0001] The present invention relates to a vehicle interior structure. [Background technology]

[0002] When another vehicle collides with a vehicle from the side, the panel located on the side of the seat where the occupant sits may protrude into the passenger compartment, potentially affecting the occupant sitting in the seat. For this reason, as described in JP 2021-123223 A (Patent Document 1), it is conceivable to form a bulge in the panel located on the side of the seat that follows the seat, thereby improving the strength of the side of the vehicle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-123223 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the technology described in Patent Document 1, when another vehicle collides with the vehicle from the side, the head of the occupant sitting in the seat may move suddenly toward the panel due to inertia, causing the occupant's head to collide with the panel and causing an impact.

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vehicle interior structure that can protect the head of an occupant seated in a seat during a vehicle collision. [Means for solving the problem]

[0006] The vehicle interior structure has a head pad attached to a body panel located to the side of the head of an occupant of standard build seated in a seat, at a position facing the occupant's head. [Effects of the Invention]

[0007] According to the present invention, the head of an occupant seated in a seat can be protected in the event of a vehicle collision. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 show an example of a vehicle interior structure 100 to which this embodiment can be applied. Note that the vehicle interior structure 100 described below is merely an example showing one example of this embodiment, and should not be construed as being limited to this configuration.

[0010] The vehicle interior structure 100 is configured by appropriately joining, by spot welding or the like, a front floor panel 110 and a back floor panel 120 constituting the floor walls, a back cabin panel 130 constituting the rear wall, a pair of left and right front side panels 140, a roof side panel 150, a side cabin panel 160, and a wheel well inner panel 170 constituting both side walls, a front panel (not shown) constituting the front wall, and a roof panel (not shown) constituting the ceiling wall. Examples of the various panels include the front floor panel 110, the back floor panel 120, the back cabin panel 130, the front side panel 140, the roof side panel (including so-called A-pillar panels) 150, a door panel 330 (see FIG. 5 ), the side cabin panel 160, and the wheel well inner panel 170, which will be described later. The back cabin panel 130 is used to provide a back space in the rear of the vehicle interior for storing luggage and the like. These various panels refer to vehicle body panels made of steel plates or the like and forming vehicle body frame members.

[0011] A windshield opening (not shown) into which a windshield is attached is formed at a predetermined location on the front panel that constitutes the front wall of the passenger compartment. A door opening DO into which a door panel 330 (described later) is attached so as to be able to open and close is formed at a predetermined location on the joined body of the front side panels 140, roof side panels 150, and side cabin panels 160 that constitute both side walls of the passenger compartment. A side glass opening SO into which a side glass is attached is formed at a predetermined location on the side cabin panels 160 that constitute both side walls of the passenger compartment. A rear glass opening RO into which a rear glass is attached is formed at a predetermined location on the back cabin panel 130.

[0012] A pair of left and right seats 180 (seats) for occupants to sit on are attached to predetermined locations on a front floor panel 110 that constitutes the floor wall of the vehicle compartment, side by side in the left-right direction of the vehicle (only the right seat 180 is shown in FIG. 1). The seat 180 has a seat cushion 180A fixed to predetermined locations on the front floor panel 110, and a headrest-integrated seat back 180B that is recliningly fixed to the rear end of the seat cushion 180A. A center console 190 is also attached between the pair of left and right seats 180.

[0013] The side cabin panel 160, located rearward of the door opening DO, cooperates with a pillar outer panel 200 located laterally outward to form a center pillar CP. A portion of the side cabin panel 160 adjacent to its front end is formed in a hat shape that protrudes toward the interior of the vehicle over the entire vertical length of the vehicle cabin. A portion of the pillar outer panel 200 adjacent to its front end is formed in a hat shape that protrudes toward the exterior of the vehicle cabin over the entire vertical length of the vehicle cabin. The side cabin panel 160 and the pillar outer panel 200 are then overlapped and the overlapping portion is joined by spot welding or the like to form a center pillar CP having a closed cross section.

[0014] A lower trim 210, which is an interior lining material, is attached to the inner surface of the center pillar CP facing the interior of the vehicle cabin. The lower trim 210 extends upward from the upper surface of the front floor panel 110 at a position where the seat cushion 180A of the seat 180 is attached, past the head of an occupant with a standard build. Here, the standard build refers to a build having dimensions preset in consideration of the race and other factors of the occupant in each country in which a vehicle equipped with the vehicle interior structure 100 of this embodiment is operated. The base end of the lower trim 210, i.e., the portion that is attached to the center pillar CP, is formed in a shape that imitates the hat shape of the side cabin panel 160. The front end of the lower trim 210 is fixed in a state where it sandwiches a resin lining 220 attached to the joint between the side cabin panel 160 and the pillar outer panel 200, and the rear end is fixed to the side cabin panel 160 with bolts (not shown) or the like.

[0015] A shoulder pad 230 is attached to a predetermined location on the upper portion of the lower trim 210 to cover the shoulders of an occupant with a standard build. The shoulder pad 230 is designed to contact the occupant's shoulders before the occupant's chest or abdomen during a side collision. In Japan, the major dimensions of a dummy used in a crash experiment taking into account the standard build of Japanese people can be, for example, a range of 565±7 mm from the seat cushion to the shoulder joint. The predetermined location to cover the shoulders of an occupant with a standard build may be located above the rear of the seat back 180B of the seat 180, in the range between the upper and lower ends of a steering wheel 290 (described later), or in a position adjacent to and below a seat belt anchor 270 (described later). Details of the shoulder pad 230 will be described later.

[0016] Assist grips 240 that help occupants get in and out of the vehicle are attached to the upper parts of the roof side panels 150 that form both side walls of the vehicle interior. The assist grips 240 assist the occupants in getting in and out of the vehicle by gripping them as needed when getting in and out. In addition, head pads 250 are attached from the upper parts of the roof side panels 150 that form both side walls of the vehicle interior to the upper parts of the side cabin panels 160. The head pads 250 protect the occupants' heads by catching them and preventing them from directly hitting the roof side panels 150 or the side cabin panels 160 in the event of a side collision of the vehicle. Therefore, the head pads 250 are attached at predetermined locations facing the sides of the head of the occupant seated in the seat 180. Details of the head pads 250 will be described later.

[0017] Furthermore, a seatbelt anchor (shoulder seatbelt anchor) 270 for folding back a strap (seatbelt) 260 reeled out from a retractor (not shown) arranged inside the lower trim 210 is attached to the inner surface of the center pillar CP facing the interior of the vehicle, at a location between the shoulder pad 230 and the head pad 250. The retractor, strap 260, seatbelt anchor 270, and seatbelt tongue (tongue plate) 280 form a seatbelt assembly. The seatbelt tongue 280 is detachably fixed to a seatbelt buckle 282 provided near the rear end of the seat cushion 180A of the seat 180.

[0018] A steering wheel 290, which is operated when steering the vehicle, is attached in front of the seat 180 in which the driver sits. As shown in Fig. 2, the steering wheel 290 is fixed to a steering member 300 extending in the vehicle width direction by a steering column 320 that rotatably supports a steering shaft 310. The lower end of the steering shaft 310 is connected to a steering gear box (not shown).

[0019] 4 and 5, the head pad 250 has two mounting portions 250A and 250B for mounting both longitudinal ends thereof to the side cabin panel 160 and the roof side panel 150, respectively. One of the two mounting portions 250A and 250B, specifically the mounting portion 250A located on the side cabin panel 160 side, is formed at a position recessed from the surface SF1 of the head pad 250 on which the occupant's head comes into contact. The other of the two mounting portions 250A and 250B, specifically the mounting portion 250B located on the roof side panel 150 side, is formed at a position spaced from the longitudinal end of the surface SF2 of the head pad 250 on which the occupant's head comes into contact, and is offset from the surface of the head pad 250 toward the roof side panel 150. Therefore, the assist grip 240 is provided in front of the head pad 250, and the mounting portion on the rear end side and the other mounting portion 250B of the head pad 250 are disposed adjacent to each other.

[0020] The head pad 250 is formed so that the width (vertical dimension) of one mounting portion 250A is larger than the width of the other mounting portion 250B in a plan view. A part of the lower part of the head pad 250 having such a shape is arranged at a position overlapping with a weatherstrip WS1 provided on the edge of the door opening DO, as shown in Fig. 4. Furthermore, a part of the lower part of the head pad 250 is formed in a shape that follows the weatherstrip WS1, specifically, a shape that extends linearly from the front to the rear of the vehicle interior and then curves downward along the curved corner of the door opening DO.

[0021] Furthermore, below the head pad 250, as shown in FIG. 5, a weatherstrip WS2 is disposed adjacent to the edge of the glass opening GO of the door panel 330 that is attached to the door opening DO so as to be able to open and close.

[0022] The head pad 250 is a resin cushioning member having a thin outer shell that protrudes toward the vehicle interior, and is formed with a hollow interior as shown in Fig. 6. At least one rib 250C extending at least in the vertical direction is integrally provided on the inner surface of the head pad 250. The rib 250C of the head pad 250 has a height that rises vertically from the inner surface of the head pad 250 by a predetermined dimension, but may be provided throughout the entire interior of the head pad 250.

[0023] Furthermore, cushioning materials 250D made of an elastic material such as sponge or foam rubber are arranged on the side surfaces of the ribs 250C of the head pad 250. As an example, the cushioning materials 250D are arranged on both sides of the ribs 250C. When the head pad 250 is provided with a plurality of ribs 250C, the cushioning materials 250D may be arranged between adjacent ribs 250C.

[0024] Furthermore, the height of at least one rib 250C1 located in the longitudinal middle of the head pad 250 is formed to be greater than the height of the other ribs 250C. A buffer member 250E made of sponge, foam rubber, or the like is provided at an end of the at least one rib 250C1 formed to be tall in this way, i.e., at an end on the roof side panel 150 side or the side cabin panel 160 side. Note that the buffer member 250E is not limited to being provided at the at least one rib 250C1 formed to be tall, but may also be provided at an end of the other ribs 250C.

[0025] 7, the surface of head pad 250, which the head of an occupant seated in seat 180 abuts, is positioned closer to seat 180 (toward the cabin) than the surface of shoulder pad 230, which the shoulders of the occupant seated in seat 180 abut. That is, shoulder pad 230 is positioned distal to the occupant seated in seat 180, and head pad 250 is positioned proximal to the occupant seated in seat 180. Therefore, the surface of head pad 250 is positioned closer to the cabin than the surface of shoulder pad 230, with respect to the surface of side cabin panel 160. In addition, the upper surface of head pad 250, which the occupant's head abuts, is inclined toward seat 180 (toward the cabin) than the surface of shoulder pad 230, which the occupant's shoulders abut. That is, if the angle between the upper surface of head pad 250 and the vertical plane is α and the angle between the surface of shoulder pad 230 and the vertical plane is β, then the relationship α>β holds. With regard to the shoulder pads 230 located at the bottom in Fig. 7, the shoulder pad 230 located on the left side is covered with a cover CV as a surface layer, and the shoulder pad 230 located on the right side is shown with the cover CV removed.

[0026] Furthermore, the shoulder pad 230 and the head pad 250 are arranged so as to be spaced apart in the vertical direction while protruding toward the passenger compartment from the surfaces of the roof side panel 150 and the side cabin panel 160. A seat belt anchor 270 is attached to the side cabin panel 160 located between the shoulder pad 230 and the head pad 250, i.e., to the inner surface of the center pillar CP.

[0027] According to this vehicle interior structure 100, a hollow resin head pad 250 is attached to the roof side panel 150 and the side cabin panel 160, which are located to the side of the head of an occupant seated in the seat 180, at a position facing the occupant's head. Therefore, even if the occupant's head suddenly moves outward due to inertia when another vehicle collides with the vehicle in the side, the head is received by the head pad 250, preventing the occupant's head from directly colliding with the roof side panel 150 or the side cabin panel 160. As a result, the impact acting on the occupant's head during a vehicle side collision is reduced, and the occupant's head can be protected. In Japan, the position from which the occupant's head faces can be above the seat 180 (for example, above the rear of the seat cushion 180A or above the seat surface of the seat back 180B) at a height within the range of, for example, 565±7 mm, which is the dimension from the seat surface to the shoulder joint, in a side view of the seat, and 909±9 mm, which is the seat height, which is the height from the seat surface to the top of the head of the dummy when seated in the seat, as the main dimensions of a dummy used in crash tests that take into account the standard body type of Japanese people. Alternatively, the position from which the occupant's head faces can be above the seat 180 (for example, above the rear of the seat cushion 180A or above the seat surface of the seat back 180B) at a height corresponding to the headrest of the seat back 180B of the seat 180, or at a height adjacent to and above the seat belt anchor 270, in a side view of the seat.

[0028] The features and additional features that can be understood from the above-described embodiments will be listed below together with their effects.

[0029] <Feature 1> As shown in FIGS. 1 to 3 , the vehicle interior structure 100 includes a seat 180 on which an occupant sits, a roof side panel 150 and a side cabin panel 160 as vehicle body panels positioned on either side of the seat 180 to form the vehicle interior, and a head pad 250. Here, the head pad 250 is attached to the roof side panel 150 and the side cabin panel 160, which are vehicle body panels positioned on either side of the head of an occupant with a standard build seated in the seat 180, at a position facing the occupant's head. In this way, even if the occupant's head suddenly moves outward due to inertia when another vehicle collides with the vehicle from the side of the seat 180 (in a seat side collision), the head is received by the head pad 250, preventing the occupant's head from directly colliding with the side wall of the vehicle interior positioned on the side of the seat 180. As a result, the impact acting on the occupant's head in a vehicle seat side collision is reduced, thereby protecting the occupant's head.

[0030] <Feature 2> The head pad 250 is formed in a hollow shape, as shown in Fig. 6. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, the head pad 250 can deform and absorb the impact acting on the occupant's head.

[0031] <Feature 3> As shown in Fig. 6, at least one rib 250C extending in the vertical direction is formed on the inner surface of the hollow head pad 250. With this configuration, even if the occupant's head collides with the head pad 250 and is significantly deformed during a vehicle side collision, the rib 250C prevents the head pad 250 from deforming to the roof side panel 150 or the side cabin panel 160. This prevents the head pad 250 from bottoming out against the roof side panel 150 or the side cabin panel 160, thereby providing better protection for the occupant's head.

[0032] <Feature 4> As shown in Fig. 6, a cushioning material 250D made of a cushion, foam rubber, or the like is disposed inside the hollow head pad 250. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, the cushioning material 250D can absorb the impact acting on the occupant's head by deformation of the cushioning material 250D. In addition, the cushioning material 250D can also prevent the head pad 250 from bottoming out against the roof side panel 150 or the side cabin panel 160.

[0033] <Feature 5> 6, cushioning material 250D is disposed on the side surface of rib 250C of head pad 250. In this way, even if the occupant's head collides with head pad 250 during a side collision of the vehicle seat, the cushioning material 250D deforms to absorb the impact acting on the occupant's head, while the rib 250C is broken, preventing the head pad 250 from bottoming out against roof side panel 150 or side cabin panel 160.

[0034] <Feature 6> 6, the cushioning material 250D is disposed on both sides of the rib 250C. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, deformation of the rib 250C to both sides is suppressed, thereby enhancing the effect of Feature 5. The cushioning materials 250D disposed on both sides of the rib 250C may be integral or separate.

[0035] <Feature 7> 6, the cushion material 250D is disposed between adjacent ribs 250C. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, deformation of the ribs 250C disposed on both sides of the cushion material 250D is suppressed, thereby enhancing the effects of Features 4 and 5.

[0036] <Feature 8> 6, a buffer member 250E made of sponge, foam rubber, or the like is provided at the end of the rib 250C on the roof side panel 150 side or the side cabin panel 160 side. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, the impact is absorbed by the buffer member 250E arranged between the end of the rib 250C and the roof side panel 150 or the side cabin panel 160. This prevents the rib 250C from being damaged by the impact force, and prevents the head pad 250 from bottoming out against the roof side panel 150 or the side cabin panel 160.

[0037] <Feature 9> As shown in FIG. 6, among the multiple ribs 250C formed on the inner surface of the head pad 250, at least one rib 250C1 located in the longitudinal middle portion of the head pad 250 is formed to have a height greater than the heights of the other ribs 250C. Here, the longitudinal middle portion of the head pad 250 is the portion where, for example, the head of an occupant with a standard build seated in the seat 180 is expected to first come into contact. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, damage to the rib 250C1 at the portion where the occupant's head collides is suppressed, and the head pad 250 can be prevented from locally bottoming out against the roof side panel 150 or the side cabin panel 160. Furthermore, because the other ribs 250C have a small height, deformation of the head pad 250 is not hindered, and the impact acting on the occupant's head can be absorbed.

[0038] <Feature 10> 6, at least one rib 250C1 formed with a large height is provided with a cushioning member 250E made of sponge, foam rubber, or the like at an end portion on the roof side panel 150 side or the side cabin panel 160 side. As in Feature 9, this configuration suppresses damage to the rib 250C at the portion where the occupant's head abuts, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, and prevents the head pad 250 from locally bottoming out against the roof side panel 150 or the side cabin panel 160. Even if the other ribs 250C around the at least one rib 250C1 formed with a large height are broken when the occupant's head is received by the head pad 250 during a side collision of the vehicle seat, the cushioning member 250E provided at the end portion of the at least one rib 250C1 with a large height can suppress the head pad 250 from locally bottoming out against the roof side panel 150 or the side cabin panel 160.

[0039] <Feature 11> 8, at least one rib 250C1 having a greater height has a portion 250C2 that extends closer to the roof side panel 150 or the side cabin panel 160 than the other ribs 250C, and a buffer member 250E (not shown) is provided at that portion 250C2. In this way, since the portion 250C2 where the buffer member 250E is provided is located closer to the roof side panel 150 or the side cabin panel 160 than the other portions, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, the impact can be absorbed by the portion 250C2 and the buffer member 250E provided there.

[0040] <Feature 12> Although not clearly shown in the accompanying drawings, portion 250C2 of at least one rib 250C1 has cushioning material 250D provided at a location distal from roof side panel 150 and side cabin panel 160, i.e., on the rear surface side of the outer contour of head pad 250. In this way, even if the occupant's head collides with head pad 250 during a side collision of the vehicle seat, the collision energy can be absorbed as deformation energy of cushioning material 250D while still achieving the effect of Feature 9.

[0041] <Feature 13> The base end of the head pad 250, on which at least one tall rib 250C1 is formed, has a cutout 250F cut out in part to reduce its rigidity, as shown in Fig. 8. This promotes deformation of the head pad 250 when the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, thereby mitigating the impact acting on the occupant's head.

[0042] <Feature 14> 4 and 5, the head pad 250 has two attachment portions 250A and 250B for attachment to the roof side panel 150 or the side cabin panel 160. One attachment portion 250A is formed at a position recessed from the surface of the head pad 250 toward the roof side panel 150 or the side cabin panel 160. The other attachment portion 250B is formed at a position spaced apart from the longitudinal end of the head pad 250 and offset from the surface of the head pad 250 toward the roof side panel 150 or the side cabin panel 160. In this manner, one attachment portion 250A suppresses misalignment of the head pad 250 with respect to the roof side panel 150 or the side cabin panel 160, while the other attachment portion 250B is spaced apart from the portion against which the occupant's head comes into contact, making that portion more easily deformable. Furthermore, since the two mounting portions 250A and 250B are not present in the area where the occupant's head comes into contact, the occupant's head can be prevented from coming into direct contact with the two mounting portions 250A and 250B, which have higher rigidity than other areas.

[0043] <Feature 15> 4 and 5, the head pad 250 is formed so that the width (height dimension) on one attachment portion 250A side is larger than the width on the other attachment portion 250B side. In this way, even if the one attachment portion 250A formed at a position recessed from the surface of the head pad 250 makes it difficult for the surrounding area to deform, the wider portion can support the occupant's head and make it easier to deform.

[0044] <Feature 16> As shown in Figures 1 and 2, a joined body such as a front side panel 140, a roof side panel 150, and a side cabin panel 160 positioned on the side of the seat 180 has a door opening DO. As shown in Figures 4 and 5, a weatherstrip WS1 made of an elastic material or the like is provided on the edge of the door opening DO, and a portion of the head pad 250 is positioned so as to overlap the weatherstrip WS1. In this way, a portion of the impact force transmitted from the occupant's head to the head pad 250 can be absorbed by the elastic deformation of the weatherstrip WS1.

[0045] <Feature 17> 4 and 5, the lower part of the head pad 250 is formed in a shape that follows the weatherstrip WS1. This increases the area where the head pad 250 overlaps with the weatherstrip WS1, thereby improving the absorption effect of the impact force transmitted from the occupant's head to the head pad 250.

[0046] <Feature 18> 4 and 5, the corners of the door opening DO formed in the joined body of the roof side panel 150, the roof side panel 150, and the side cabin panel 160 are curved, i.e., formed in an arc shape with a predetermined radius. The lower part of the head pad 250 is curved along the corners of the door opening DO. This further increases the area where the head pad 250 overlaps with the weatherstrip WS1, thereby further improving the absorption effect of the impact force transmitted from the occupant's head to the head pad 250.

[0047] <Feature 19> As shown in FIG. 5 , a weatherstrip WS2 is disposed adjacent to the head pad 250 below the head pad 250. The weatherstrip WS2 is attached to the edge of the glass opening GO of the door panel 330, which is attached to the door opening DO so as to be able to open and close. In this way, even if the occupant's head is displaced below the head pad 250 during a side collision of the vehicle, the occupant's head can be brought into contact with the weatherstrip WS2 disposed below the head pad 250, and the impact energy can be absorbed by the elastic deformation. To achieve this effect, for example, the corners of the glass opening GO can be positioned close to the corners of the door opening DO, and the weatherstrip WS1 disposed on the door opening DO and the weatherstrip WS2 disposed on the glass opening GO can be positioned close to each other. Furthermore, it is even more preferable to provide a portion of the head pad 250 with a large vertical width around the area where the two weatherstrips WS1 and WS2 are adjacently disposed.

[0048] <Feature 20> 5, the assist grip 240 is provided in front of the head pad 250, and the attachment portion on the rear end side of the assist grip 240 and the other attachment portion 250B of the head pad 250 are disposed adjacent to each other. This increases the rigidity around the fixing point of the assist grip 240, improving the fixing strength of the other attachment portion 250B of the head pad 250 and suppressing displacement of the head pad 250.

[0049] <Feature 21> As shown in FIGS. 1 to 3, shoulder pads 230 are attached to side cabin panels 160 located to the sides of the shoulders of an occupant seated in seat 180 in positions facing the occupant's shoulders. In this way, even if side cabin panel 160 or the like protrudes toward the passenger compartment during a side collision of the vehicle seat, the occupant's shoulders are pushed toward the passenger compartment while abutting against shoulder pad 230, making it easier to maintain a distance between the occupant's chest and abdomen, which are located below the occupant's shoulders, and the side cabin panel 160. This prevents the occupant's chest and abdomen from coming into contact with side cabin panel 160, thereby protecting the occupant.

[0050] <Feature 22> 7, the surface of head pad 250 is disposed closer to seat 180 than the surface of shoulder pad 230. In this way, the occupant's head hits head pad 250 first during a side collision of the vehicle seat, reducing the angle at which the occupant's head tilts outward due to inertia, thereby reducing the impact force transmitted from head pad 250 to the occupant's head.

[0051] <Feature 23> 7, the upper surface of the head pad 250 is inclined toward the seat 180 more than the surface of the shoulder pad 230. This configuration can prevent the head of an occupant sitting in the seat 180 from contacting the head pad 250 under normal circumstances. Furthermore, in the event of a side collision of the vehicle seat, the head of the occupant leaning outward from the cabin is more likely to come into surface contact with the head pad 250, preventing localized impact force from acting on the occupant's head.

[0052] <Feature 24> 7, shoulder pad 230 has an inclined portion that slopes outward from the vehicle cabin below the portion facing the shoulders of an occupant with a standard build seated in seat 180. In this way, even if the occupant's shoulders are displaced downward during a side collision of the vehicle seat, the occupant's shoulders will come into contact with the inclined portion, so the distance between the occupant's chest or abdomen and side cabin panel 160 can be maintained.

[0053] <Feature 25> 7, the upper surface of head pad 250 against which the occupant's head comes into contact is inclined toward seat 180 relative to the surface of shoulder pad 230 against which the shoulder of the occupant sitting in seat 180 comes into contact. In this way, even if the relative positions of the occupant's shoulder and shoulder pad 230 shift during a side collision of the vehicle seat and the periphery of the shoulder comes into contact with the inclined portion, the occupant's head comes into contact with head pad 250 early, thereby reducing the impact force.

[0054] <Feature 26> 7, the shoulder pad 230 and the head pad 250 are arranged to be spaced apart from each other in the vertical direction and protrude from the surface of the side cabin panel 160 toward the passenger compartment. A seat belt anchor 270 is attached to the side cabin panel 160 located between the shoulder pad 230 and the head pad 250. In this way, the attachment position of the seat belt anchor 270 relative to the passenger compartment is positioned outward to ensure space, and the head or shoulders of an occupant seated in the seat 180 can be made to easily come into contact with the head pad 250 or the shoulder pad 230 in the event of a side collision of the vehicle.

[0055] <Feature 27> 7, the surface of the head pad 250 is inclined more toward the passenger compartment than the surface of the side cabin panel 160. In this way, an effect similar to that of feature 23 can be achieved.

[0056] In addition to these features 1 to 27, the following features can also be mentioned, which are clearly shown in FIGS.

[0057] <Feature A> The upper portion of the shoulder pad 230 has a flat surface portion A that is flat in the vertical direction. This makes it possible to prevent the occupant from coming into contact with the shoulder pad 230 under normal circumstances.

[0058] <Feature B> The lower part of the flat portion A of the shoulder pad 230 has an inclined portion B that is spaced apart from the seat back 180B of the seat 180. In this way, the occupant can avoid contact with the shoulder pad 230 under normal circumstances.

[0059] <Feature C> Seat back 180B of seat 180 has recessed portion C (or stepped portion C) recessed into the vehicle interior to avoid shoulder pad 230. This increases the contact area between the occupant's shoulder and shoulder pad 230 in the event of a side collision of the vehicle seat.

[0060] <Feature D> The seat back 180B of the seat 180 has a protrusion D that protrudes outward in the width direction of the vehicle below the recess C (or step C). In this way, the seat back 180B of the seat 180 can absorb external forces from the side wall in the event of a side collision of the vehicle seat.

[0061] <Feature E> Between the recessed portion C (or stepped portion C) and the protruding portion D of the seat back 180B of the seat 180, an inclined portion E is provided that slopes downward and outward in the width direction of the vehicle along the inclined portion of the shoulder pad 230. In this way, it becomes easier to transmit external force from the protruding portion D to the recessed portion C (or stepped portion C), thereby enhancing the effect of the feature D.

[0062] The following modifications can be made to the above-described embodiment. The head pad 250 and the shoulder pad 230 form a trim, which is a single interior material attached from the roof side panel 150 to the side cabin panel 160, and the trim may have a member connecting the head pad 250 and the shoulder pad 230. This makes it easier to maintain and adjust the relative positions of the head pad 250 and the shoulder pad 230. In addition, because the surface of the side cabin panel 160 located between the head pad 250 and the shoulder pad 230 is covered with the trim, it is possible to prevent an occupant sitting in the seat 180 from directly contacting the side cabin panel 160 in the event of a side collision of the vehicle.

[0063] The member connecting the head pad 250 and the shoulder pad 230 can also be attached using a fastener such as a bolt that fastens the seat belt anchor 270 to the side cabin panel 160. In this way, it is possible to prevent the head pad 250 and the shoulder pad 230 from shifting in position relative to the roof side panel 150 and the side cabin panel 160.

[0064] The cushion material 250D arranged on the inner surface of the head pad 250 may be arranged above, rather than below, the head pad 250, as shown by the two-dot chain line in Fig. 8. In this case, the cushion material 250D may or may not be present below the head pad 250. In this way, even if the head of an occupant seated in the seat 180 collides with the head pad 250 during a side collision of the vehicle, the cushion material 250D arranged above the head pad 250 can prevent the head pad 250 from bottoming out against the leaf side panel 150 and the side cabin panel 160.

[0065] 8, the cushion material 250D arranged inside the head pad 250 may be arranged to extend in the longitudinal direction of the head pad 250 while avoiding the plurality of ribs 250C. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, the impact energy is absorbed by the elastic deformation of the entire cushion material 250D arranged inside, and the head pad 250 can be prevented from bottoming out against the roof side panel 150 and the side cabin panel 160.

[0066] Although not clearly shown in the drawings, the cushion material 250D arranged inside the head pad 250 may be arranged between all of the ribs 250C arranged on the inner surface thereof. In this way, even if the occupant's head collides with the head pad 250 during a side collision of the vehicle seat, the impact force when the occupant's head collides with the head pad 250 can be reduced by the elastic deformation of the cushion material 250D arranged throughout the inside of the head pad 250.

[0067] Furthermore, the vehicle interior structure 100 does not need to have a back space behind the seat 180, as shown in Fig. 9. In this case, the vehicle interior structure 100 does not need to include a back floor panel 120, and it is sufficient that the back cabin panel 130 is joined to the rear end of the front floor panel 110 by spot welding or the like. Also, the seat back 180B of the seat 180 is not limited to a configuration in which it is reclined and fixed to the rear end of the seat cushion 180A, and may be fixed to the back cabin panel 130 so as not to be reclined, as shown in Fig. 9. Furthermore, the seat back 180B of the seat 180 is not limited to a type integrated with a headrest, but may also be a type with a separate bed rest.

[0068] In this embodiment, a side collision in which an occupant is seated in seat 180 facing forward is assumed as a vehicle seat side collision. However, this embodiment is also applicable to a case in which an occupant is seated in seat 180 facing inward in the vehicle width direction, such as when seat 180 is arranged so that seat cushion 180A of seat 180 faces inward in the vehicle width direction. In this case, a vehicle body panel (e.g., back cabin panel 130, a back door panel (not shown), or a partition panel separating the front seat space from the rear seat space) is arranged on the side of seat 180, i.e., in front of or behind seat 180, and head pad 250 can be attached to a position facing the head of an occupant of a standard build seated in seat 180 on the vehicle body panel located to the side of the head of the occupant. In this way, the occupant's head can be protected even in a so-called frontal collision or rear collision during a vehicle seat side collision.

[0069] Those skilled in the art will readily understand that new embodiments can be created by omitting parts of the technical ideas of the various above-described embodiments, combining parts of the ideas appropriately, or replacing parts of the ideas with well-known technology.

[0070] For example, the head pad 250 may be arranged to overlap the door panel 300 and the roof side panel 150 or the side cabin panel 160. In this case, the head pad 250 is separated into a head pad 250A on the door panel 330 side and a head pad 250B on the roof side panel 150 side or the side cabin panel 160 side, thereby making it easier to open and close the door panel 330. The head pad 250 and the shoulder pads 230 may be integrally formed via a connecting portion, for example. In this case, it is preferable to form the connecting portion in a thin plate shape and arrange the head pad 250 and the shoulder pads 230 so that they protrude into the vehicle cabin beyond the connecting portion.

[0071] The technical concept of the invention as defined in the claims and its effects are listed below.

[0072] <Technical philosophy 1> The vehicle interior structure has a head pad attached to a body panel located to the side of the head of a standard-sized occupant seated in the seat, at a position facing the occupant's head. In this way, even if the occupant's head moves suddenly outward due to inertia when another vehicle collides with the vehicle from the side of the seat, the head is received by the head pad, preventing the occupant's head from directly colliding with the side wall of the vehicle interior. As a result, the impact acting on the occupant's head during a side collision of the vehicle seat is reduced, thereby protecting the occupant's head.

[0073] <Technical philosophy 2> The vehicle body panel has an opening, a weatherstrip is provided on the edge of the opening of the vehicle body panel, and a part of the head pad is positioned so as to overlap the weatherstrip. In this way, part of the impact force transmitted from the occupant's head to the head pad can be absorbed by elastic deformation of the weatherstrip.

[0074] <Technical philosophy 3> The lower part of the head pad is shaped to fit the weatherstrip, which increases the area where the head pad overlaps with the weatherstrip, improving the absorption of the impact force transmitted from the occupant's head to the head pad.

[0075] <Technical philosophy 4> The corners of the opening in the body panel are curved, and the lower part of the head pad is curved along the corners. This further increases the area where the head pad overlaps with the weatherstrip, further improving the absorption effect of the impact force transmitted from the occupant's head to the head pad.

[0076] <Technical philosophy 5> A weatherstrip is disposed adjacent to the bottom of the head pad, and is attached to the edge of the glass opening of a door panel that is openably attached to an opening in a vehicle body panel. In this way, even if the occupant's head is displaced below the head pad during a side collision of the vehicle, the occupant's head will come into contact with the weatherstrip disposed below the head pad, and the impact energy can be absorbed by the elastic deformation of the weatherstrip.

[0077] <Technical philosophy 6> The head pad has two mounting portions for mounting to a vehicle body panel, one of which is recessed from the surface of the head pad toward the vehicle body panel, and the other of which is spaced from the longitudinal end of the head pad and offset from the surface of the head pad toward the vehicle body panel. This configuration prevents the head pad from shifting relative to the vehicle body panel using one mounting portion, while separating the other mounting portion from the area where the occupant's head comes into contact, allowing that area to deform more easily. Furthermore, because there are no two mounting portions at the area where the occupant's head comes into contact, the occupant's head can be prevented from directly contacting the two mounting portions, which are more rigid than other areas.

[0078] <Technical philosophy 7> The head pad is formed so that one of the two mounting portions is wider. In this way, even if one mounting portion formed in a recessed position from the surface of the head pad makes it difficult for the surrounding area to deform, the wider portion can support the occupant's head and make it easier to deform.

[0079] <Technical philosophy 8> An assist grip is provided on the other attachment portion side of the periphery of the head pad, and the attachment portion of the assist grip and the other attachment portion of the head pad are arranged adjacent to each other. This increases the rigidity around the fixed point of the assist grip, improving the fixing strength of the other attachment portion of the head pad and suppressing displacement of the head pad.

[0080] <Technical philosophy 9> The head pad is hollow and has at least one rib extending vertically on its inner surface. This prevents the head pad from deforming into the body panel even if the occupant's head collides with the head pad and deforms significantly during a side collision. This prevents the head pad from bottoming out against the body panel, providing better protection for the occupant's head.

[0081] <Technical Thought 10> Cushioning material is placed on the side of the rib of the head pad. In this way, even if the occupant's head collides with the head pad during a side collision of the vehicle seat, the cushioning material deforms to absorb the impact acting on the occupant's head, while preventing the rib from breaking and the head pad from bottoming out against the vehicle body panel.

[0082] <Technical Thought 11> The cushioning material is disposed on both sides of the rib, which prevents the rib from deforming to either side even when the occupant's head strikes the head pad during a side collision of the vehicle seat, thereby enhancing the effect of Technical Idea 10.

[0083] <Technical Thought 12> A plurality of ribs are provided, and cushioning material is disposed between adjacent ribs. In this way, even if the occupant's head collides with the head pad during a side collision of the vehicle seat, deformation of the ribs disposed on both sides of the cushioning material is suppressed, thereby enhancing the effect of Technical Idea 10.

[0084] <Technical Thought 13> A shock absorber is provided at the end of the rib on the vehicle body panel side. In this way, even if the occupant's head strikes the head pad during a side collision of the vehicle seat, the shock absorber disposed between the end of the rib and the vehicle body panel absorbs the impact. This prevents the rib from being damaged by the impact force, preventing the head pad from bottoming out against the vehicle body panel.

[0085] <Technical Thought 14> The head pad is provided with a plurality of ribs, and at least one rib located in the longitudinal middle of the head pad has a height greater than the other ribs. This configuration suppresses damage to the ribs at the location where the occupant's head strikes the head pad during a side collision of the vehicle seat, preventing the head pad from bottoming out locally against the body panel. Furthermore, because the other ribs have a small height, deformation of the head pad is not inhibited, allowing the head pad to absorb the impact acting on the occupant's head.

[0086] <Technical Thought 15> A buffer member is provided on the end of at least one rib formed to be tall, which is located on the vehicle body panel side. In this way, as with Technical Idea 14, even if the occupant's head collides with the head pad during a side collision of the vehicle seat, damage to the rib at the portion where the occupant's head abuts is suppressed, and the head pad can be prevented from locally bottoming out against the vehicle body panel. Furthermore, even if the other ribs around the at least one rib formed to be tall are broken when the occupant's head is received by the head pad during a side collision of the vehicle seat, the buffer member provided on the end of the at least one rib formed to be tall can prevent the head pad from locally bottoming out against the vehicle body panel.

[0087] <Technical Thought 16> A shoulder pad is attached to a body panel located to the side of the shoulder of a seated occupant in a position facing the occupant's shoulder. This structure minimizes damage to the ribs at the location where the occupant's head strikes the head pad, preventing the head pad from bottoming out locally against the body panel, even if the occupant's head strikes the head pad during a side collision of the vehicle seat. Furthermore, the other ribs are small in height, allowing the head pad to deform freely and absorbing the impact on the occupant's head.

[0088] <Technical Thought 17> The surface of the head pad is positioned closer to the seat than the surface of the shoulder pad. In this way, the occupant's head hits the head pad first in the event of a side collision of the vehicle seat, reducing the angle at which the occupant's head tilts outward due to inertia, thereby reducing the impact force transmitted from the head pad to the occupant's head.

[0089] <Technical Thought 18> The upper surface of the head pad is inclined more toward the seat than the surface of the shoulder pad. This prevents the head of an occupant sitting in the seat from contacting the head pad under normal circumstances. Also, in the event of a side collision of the vehicle seat, the occupant's head is tilted outward from the passenger compartment and is more likely to come into surface contact with the head pad, preventing localized impact force from acting on the occupant's head.

[0090] <Technical Thought 19> The head pad and shoulder pad are disposed vertically spaced apart and protrude from the surface of the vehicle body panel toward the passenger compartment, and a seat belt anchor is attached to the vehicle body panel located between the head pad and the shoulder pad. In this way, the seat belt anchor is attached outward from the passenger compartment to ensure space, while making it easier for the head or shoulders of an occupant seated in the seat to come into contact with the head pad or shoulder pad in the event of a side collision of the vehicle.

[0091] <Technical Thought 20> The surface of the head pad is inclined toward the passenger compartment relative to the surface of the body panel. In this way, the same effect as that of Technical Idea 18 can be achieved.

[0092] <Technical Thought 21> The head pad is hollow and contains a cushioning material. This allows the cushioning material to deform and absorb the impact on the occupant's head when the occupant's head strikes the head pad during a side collision. The cushioning material also prevents the head pad from bottoming out against the vehicle body panel.
