Description

The disclosed technology relates to the structure of a vehicle seat.

Vehicle seats are required not only to be comfortable to sit on and to look good, but also to be stable enough to firmly support a seated user during driving or in the event of a collision.

Regarding the disclosed technology, Patent Document 1 discloses a rear seat of a vehicle that is designed to be lightweight and comfortable to sit on. The rear seat (seat cushion) is constructed by laminating a soft surface layer pad and a hard back layer pad. The rear seat is attached to the vehicle by inserting a fixture fixed to the back layer pad into an attachment hole provided in the floor panel.

In Patent Document 1, the intermediate portion of the rear seat where the buttocks of a seated user are located is made softer than the other portions (the surface layer pad is thin and the back layer pad is thick) to improve sitting comfort. there is By making the front and rear edges of the rear seat relatively hard, it is possible to prevent the user from slipping in the front-rear direction and shifting their position. suppressed.

Japanese Patent Laid-Open No. 2002-100001 also discloses a rear seat that suppresses the user from slipping in the front-rear direction. Patent Literature 2, in particular, aims to suppress a phenomenon in which the user slides forward at the time of collision (so-called submarine phenomenon). That is, if the rear seat is simply attached to the floor panel via a fixture as in the case of the rear seat disclosed in Patent Document 1, the fixture may come off due to the impact of a collision, and the user may slip forward together with the rear seat. Patent Literature 2 aims at suppressing such forward slippage.

The rear seat (seat cushion) of Patent Document 2 is composed of a soft cushion pad and a hard slip control member. The slip control member consists of a triangular prism-shaped block body having an upwardly inclined surface on the upper side, and is fixed to the lower front side of the cushion pad. The floor panel is provided with a floor inclined surface portion that slopes downward toward the front. A recess is provided in the rear seat, and the protrusion and the recess constitute a stopper mechanism that suppresses forward slippage of the rear seat.

Although there is nothing equivalent to a pad, a rear seat that suppresses the submarine phenomenon is also disclosed in Patent Document 3.

JP 2010-125138 A JP 2017-30407 A JP 2010-12887 A

According to the rear seat of Patent Document 2, the slip control member of the seat is fixed to the floor panel, and even if a strong force acts on the user in the event of a collision, the inclined surface of the slip control member receives the force. It can prevent slippage.

However, since the slip control member is fixed to the floor panel, it does not move. In addition, since the upper end of the slip-regulating member is angular, when the seated user moves, the corners of the slip-regulating member come into contact with the corners of the slip-regulating member. In addition, since the user's seating posture is restricted by the slip control member, it is easy for the user to get tired after riding for a long time.

Accordingly, an object of the technology disclosed is to realize a vehicle seat that can effectively suppress forward slippage and is comfortable to sit on.

The disclosed technology relates to a vehicle seat.

The vehicle seat includes a cushion arranged on a floor panel so as to extend in the vehicle width direction, and a material having a higher rigidity than the cushion, and is integrated with the cushion to provide a seat for the vehicle. and a pad arranged to extend in the width direction. The pad is provided movably with respect to the floor panel while being restricted from forward movement more than a predetermined amount by a first restricting member provided on the floor panel.

That is, according to this vehicle seat, the seat is configured by integrating a relatively soft cushion and a relatively hard pad with high rigidity. Therefore, it is possible to secure a sense of stability at the time of sitting by the pad while securing good sitting comfort with the cushion.

A hard pad may give the seated user a feeling of foreignness, but in this vehicle seat, the pad is provided so as to be able to move relative to the floor panel, so even if the seated user moves, the movement of the seat will be smooth. Since the pad also moves to some extent according to the movement, the feeling of a foreign object can be alleviated. Therefore, good sitting comfort can be achieved.

Since the pad is restricted from moving forward beyond a predetermined amount by the first restricting member provided on the floor panel, a strong forward force acts on the seated user when the vehicle collides. However, forward slippage can be effectively suppressed.

The vehicle seat further includes a wire frame attached to the pad, and the wire frame is engaged with the first restricting member to restrict forward movement of the pad beyond a predetermined amount. may be

The pad is then supported by the floor panel via the elastically deformable wire frame, allowing the pad to move with a relatively large degree of freedom. Therefore, sitting comfort can be improved. In the event of a collision, the sudden forward slippage of the pad and the user due to the impact can be mitigated by the elastic deformation of the wire frame, so the forward slippage can be suppressed more effectively.

The vehicle seat may also include the cushions arranged above and below the pad.

By doing so, the pad can be moved smoothly in the vertical direction, so that the feeling of a foreign object can be effectively suppressed.

In the vehicle seat, the pad may be restricted from tilting forward more than a predetermined amount by a second restricting member provided on the floor panel.

By doing so, the posture of the pad can be maintained without deviating from the appropriate state, so that the sense of stability when seated is improved. Since the user can be stably received by the pad, the effect of suppressing forward sliding is also improved.

In this case, it is preferable that the pad is also restricted from moving backward beyond a predetermined amount by the second restricting member.

By doing so, the pad can be stably held at an appropriate position, so that it is possible to further improve the comfort of sitting and the effect of suppressing forward slippage.

In the vehicle seat, the pad may have a curved seating surface that is curved and recessed in the vehicle width direction.

This will further improve the sense of stability when sitting. In addition, since the user can be guided to sit at a proper position, the effect of suppressing forward slippage can be improved.

According to the disclosed technology, it is possible to realize a vehicle seat that can effectively suppress forward slippage and is comfortable to sit on.

Embodiments of the disclosed technology will be described in detail below with reference to the drawings. However, the following description is essentially merely an example, and does not limit the present invention, its applications, or its uses. Note that the front-rear, left-right, and up-down directions used in the description are based on the normal state of the vehicle.

<Vehicle>
1 and 2 illustrate an automobile 1 (vehicle) to which the technology disclosed is applied. This automobile 1 is of a general sedan type, and two door openings 3F and 3R are arranged in the front-rear direction on the sides of the body 2 that constitutes the outer shell of the automobile, with the center pillar 2a as a boundary. formed. Although FIG. 1 and the like show the left side of the vehicle, the right side has the same structure.

Swing doors 4F, 4R are attached to these door openings 3F, 3R, respectively (in FIG. 1, the rear swing door 4R is indicated by a virtual line). Front ends of the swing doors 4F, 4R are swingably supported by the front edges of the door openings 3F, 3R. The door openings 3F, 3R are opened and closed by swinging the swing doors 4F, 4R by operating the door handles.

The floor surface of the body 2 is composed of a pair of side sills 2b, 2b extending in the front-rear direction along both left and right lower edge portions of the body 2, and a floor panel 2c covering between the side sills 2b, 2b. The ceiling surface of the body 2 is composed of a pair of roof side rails 2d, 2d extending in the front-rear direction along both left and right upper edges of the body 2, and a roof panel 2e covering between the roof side rails 2d, 2d. there is

The lower edges of the door openings 3F, 3R are formed by the side sills 2b, and the upper edges of the door openings 3F, 3R are formed by the roof side rails 2d. A compartment 5 is formed inside the body 2 by being partitioned by the floor panel 2c, the roof panel 2e, and the like.

A front seat (not shown) consisting of a driver's seat and a front passenger's seat and a rear seat 6 are installed in the vehicle compartment 5 so as to be aligned in the front-rear direction. The front seat is arranged adjacent to the front door opening 3F, and the rear seat 6 is arranged adjacent to the rear door opening 3R.

<Rear seat 6>
The rear seat 6 is a horizontally long seat, and is configured so that a plurality of people (two adults in the figure) can be seated. The rear seat 6 includes a seat cushion 6a, a seat back 6b, a headrest 6c, and the like. A seat belt is attached to the rear seat 6, but its description is omitted.

The seat cushion 6a is a part that supports the buttocks of a seated user (passenger), and is placed on the floor panel 2c. The seat back 6b is a part that supports the back of the seated user, and is provided so as to extend obliquely rearward from the rear edge of the seat cushion 6a. The headrest 6c is a part that supports the head of a seated user, and is provided above the seatback 6b.

Since this rear seat 6 is for two people, two parts (seating areas E1) where the user sits are provided on the left and right sides of the rear seat 6 . One headrest 6c is also provided in each seating area E1.

A side bolster area E2 is provided in the vicinity of the inner side of the door opening 3R. The side bolster area E2 is an area between each seating area E1 and the door opening 3R, and the rear seat 6 protrudes into the side bolster area E2 to support the seated user from the side and swing with the rear seat 6. The gap with the door 4R is narrowed. Each of the seat back 6b and seat cushion 6a has a side support 6d in the side bolster area E2.

In the case of this rear seat 6, it is possible to obtain good sitting comfort and to effectively prevent the user from slipping forward even if a strong force acts in the forward direction such as when the automobile 1 collides. The cushion 6a is devised.

3A and 3B show the seat cushion 6a. The seat cushion 6a is composed of a cushion 10, a pad 20, a wire frame 30 to be described later, and the like.

(Cushion 10)
The cushion 10 is made of a soft material with excellent elasticity, such as urethane foam (foamed resin). The surface of the cushion 10 is covered with a seat cover that is three-dimensionally constructed by sewing together a plurality of fabrics (the seat cover is not shown).

The cushion 10 has a horizontally long shape with a large thickness in the vertical direction. It has two bolster portions 13, 13 that constitute the side support 6d described above. Each bolster portion 13 has a shape that bulges relatively upward and laterally compared to the seating portion 11 .

The cushion 10 is placed on the floor panel 2c so as to extend in the vehicle width direction adjacent to the left and right door openings 3R, 3R.

(Pad 20)
The pad 20 is integrated with the cushion 10 by molding or the like. That is, the pad 20 is configured integrally with the cushion 10 by being incorporated when the cushion 10 is molded. The pad 20 is made of a material having higher rigidity and lighter weight than the cushion 10, such as plastic or aluminum alloy.

The pad 20 is shown in FIG. The pad 20 has a horizontally long plate shape. The length of the pad 20 (size in the vehicle width direction) is slightly shorter than the cushion 10 . The width (size in the front-rear direction) of the pad 20 is smaller than that of the cushion 10, and is approximately half the size of the cushion 10. As shown in FIG.

As shown in FIGS. 3A and 5 , the pad 20 is arranged so as to extend in the vehicle width direction while being more concentrated on the front side than on the rear side of the cushion 10 . The pad 20 is embedded in the cushion 10 in a slightly rearwardly inclined state so that the upper surface of the pad 20 slopes downward toward the rear. Cushions 10 are arranged above and below the pad 20 , and the pad 20 is sandwiched between the cushions 10 .

Both ends of the front side of the pad 20 are formed into an arc-shaped contour in a top view in accordance with the shape of the cushion 10 . The pad 20 has a main wall portion 21 and a pair of side end portions 22, 22 connected to both ends thereof. The main wall portion 21 supports the front portions of the seat portion 11 and the intermediate portion 12 of the cushion 10 . Each side edge 22 supports a respective bolster portion 13 of the cushion 10 . A pair of seating surfaces 21 a , 21 a are formed on the upper surface of the main wall portion 21 .

Each seating surface 21a is formed in a curved surface shape that is curved and recessed in the vehicle width direction. The lateral width of each seating surface 21a is formed to a predetermined size based on the size of the buttocks and thighs of a model (an adult having a standard body shape). The shape of each seating surface 21a is formed according to the shape of the buttocks and thighs of the model. Each seating surface 21a is arranged to be positioned in the seating area E1.

Each side end portion 22 is provided with reinforcing walls 22 a extending downward from both ends of the main wall portion 21 . A reinforcing side surface 22b is formed on the outer side of the reinforcing wall 22a in the vehicle width direction so as to extend downward to the lower end of the seat with a curved cross section. Due to the reinforcing wall 22a having the reinforcing side surface 22b having such a shape, the rigidity of each side end 22 is strengthened structurally.

A guide surface 22c that slopes downward toward the lower edge of the door opening 3R on the outer side in the vehicle width direction is formed on the upper portion of each side end portion 22. As shown in FIG. Therefore, the bolster portion 13 is positioned above the guide surface 22c. The guide surface 22c is formed continuously with the adjacent seating surface 21a via a smooth curved surface. Moreover, the guide surface 22c is formed so as to be continuous with the reinforced side surface 22b.

(Wireframe 30)
The wire frame 30 is embedded in the cushion 10 while attached to the pad 20 . A wireframe 30 is shown in FIG. 6A.

The wire frame 30 is formed by joining a plurality of elastic wires. The wire frame 30 is formed in a frame shape corresponding to the shape (mainly contour) of the cushion 10 so that the shape of the cushion 10 can be suppressed. The wire frames 30 are connected in a ring.

The wire frame 30 includes a pair of side wires 30a, 30a, a first front wire 30b, a second front wire 30c, a pair of rear hook wires 30d, 30d, a rear support wire 30e, a center wire 30f, and the like.

Each side wire 30a is arranged to extend in the front-rear direction along both left and right end portions (each bolster portion 13) of the cushion 10. As shown in FIG. The first front wire 30b and the second front wire 30c are connected to the front end of each side wire 30a. The first front wire 30b and the second front wire 30c are arranged along the front edge portion of the cushion 10 so as to extend parallel to each other.

The second front wire 30c is located behind the first front wire 30b and is arranged so as to be hooked onto the pad 20. As shown in FIG. Each of the side wires 30a and the second front wire 30c is hooked to the pad 20 along the outside of hooking portions 23 provided on the left and right reinforcing walls 22a of the pad 20. As shown in FIG. The wire frame 30 is thereby attached to the pad 20 .

Further, a pair of front hooks 31, 31 are provided by bending the second front wire 30c into a rectangular shape toward the left and right of the second front wire 30c. As shown in the enlarged view of FIG. 6A and FIG. 6B, each front hooking portion 31 is configured to be hooked by a second restricting member 40 fixed to the floor panel 2c.

The second restricting member 40 includes a base portion 40a fixed to the floor panel 2c so as to protrude upward from the floor panel 2c, and a plate-like lower restricting portion 40b provided to protrude forward from the side surface of the base portion 40a. (constituting a second lower regulation portion) , and an upper regulation portion 40c (constituting a second upper regulation portion and a second rear regulation portion) provided so as to protrude upward from the upper surface of the base portion 40a. ing. The upper restricting portion 40c is composed of a pair of L-shaped metal rods. These metal rods are arranged substantially parallel to each other with their bent ends facing forward. And each front side latching part 31 is arrange|positioned so that it may pass between the lower side control part 40b and the upper side control part 40c.

A pair of rear hook wire 30d and rear support wire 30e are arranged to extend along the rear edge portion of the cushion 10 . Each rear hook wire 30d continues to the rear end of each side wire 30a. A rear support wire 30e is laid between the left and right rear hook wires 30d, 30d.

Between each rear hook wire 30d and the rear support wire 30e, a cushioning portion is provided in which the wire is bent forward in a U shape. The center wire 30f is arranged so as to extend in the front-rear direction at a substantially intermediate portion in the vehicle width direction of the cushion 10, and is bridged between the rear support wire 30e (the portion between the two cushioning portions) and the second front wire 30c. It is As a result, the wire frame 30 has a structure like two annular frames arranged side by side.

A pair of rear hooking portions 32, 32 are provided at left and right portions of each rear hook wire 30d. As shown in the enlarged view of FIG. 6A and FIG. 6C, each rear hooking portion 32 is engaged (here, hooked) with a first restricting member 50 fixed to the floor panel 2c.

The first restricting member 50 includes a base portion 50a (constituting a first front restricting portion) fixed to the floor panel 2c so as to protrude upward from the floor panel 2c, and a base portion 50a fixed so as to protrude rearward from the rear surface of the base portion 50a. and a retaining portion 50b (constituting a first upper restricting portion) . The retaining portion 50b is composed of a pair of L-shaped or hook-shaped metal rods. These metal rods are arranged substantially parallel to each other with their bent upper ends directed rearward. Each rear hooking portion 32 is arranged to pass below the retaining portion 50b.

In this first restricting member 50, the portion of the wall surface of the floor panel 2c facing the retaining portion 50b also constitutes a part of the first restricting member (constitutes the first lower restricting portion) . The first restricting member 50 may also be provided with the base portion 40 and the lower restricting portion 40 b of the second restricting member 40 . Further, each rear hooking portion 32 may be fixed to the first restricting member 50 by welding or the like.

<Functions of the rear seat 6>
As shown in FIG. 1, the rear seat 6 is installed at a position adjacent to the door opening 3R so that the user can easily get in and out of the vehicle. Therefore, when the user opens the swing door 4R, the end (bolster portion 13) of the seat cushion 6a located in the side bolster area E2 is first seen. Therefore, the appearance of the bolster portion 13 greatly affects the overall impression of the vehicle.

As described above, since the bolster portion 13 is made of a soft material, if a load is continuously applied, the bolster portion 13 is likely to collapse and lose its shape due to deterioration over time.

On the other hand, when the user gets in and out of the vehicle, as shown in FIG. 7, the user has to pass through the narrow door opening 3R. Generally, one foot at a time straddles the lower edge of the door opening 3R while getting on and off by shifting the thigh. Therefore, the bolster portion 13 tends to deteriorate in appearance due to deterioration over time.

On the other hand, in the rear seat 6, a guide surface 22c is formed on the upper portion of the side end portion 22 of the pad 20 that supports the bolster portion 13, and the guide surface 22c faces the lower edge of the door opening 3R. It is arranged so that it slopes downward.

Therefore, when the user puts his or her weight on the bolster portion 13 , the bolster portion 13 is crushed and the buttocks or thighs come into contact with the pad 20 , though indirectly. However, since the buttocks or thighs are received by the guide surface 22c, there is almost no risk of feeling a foreign body.

Conversely, by being received by the guide surface 22c, the body weight can be safely deposited. Therefore, reliability is also improved. Furthermore, since the guide surface 22c can smoothly guide the thighs and the like to the seat portion 11, the user can smoothly shift to the seated posture.

Since the bolster portion 13 is supported by such a guide surface 22c, the thickness of the bolster portion 13 can be made relatively thin. Therefore, the bolster portion 13 is crushed and hardly loses its shape, so that deterioration of appearance can be suppressed.

Moreover, since the side end portion 22 of the pad 20 on which the guide surface 22c is formed is structurally strengthened in rigidity by the reinforced side surface 22b and the like, the cushion 10 around the pad 20 almost loses its shape. never Therefore, the bolster portion 13 becomes even more difficult to lose its shape, and deterioration in appearance can be further suppressed.

Since the seat portion 11 is supported by the seat surface 21a of the pad 20, the user hardly feels a foreign object even in a seated posture. Since the seating posture is stabilized by the seating surface 21a, it is difficult to get tired even after riding for a long time.

Further, the seat cushion 6a is not fixed to the floor panel 2c, but is attached to the floor panel 2c so as to be displaceable (floatable) in all directions with a certain degree of freedom.

Specifically, as shown in FIG. 8A, the pad 20 and the cushion 10 are movably supported by the first restricting member 50 and the second restricting member 40 via the wire frame 30 . That is, the range in which the movements of the elastically deformable cushion 10 and the wire frame 30 are restricted by the front side hooking portion 31 being hooked to the second restricting member 40, and the rear side hooking portion 32 being the first restricting member. The seat cushion 6a can be displaced in all directions within both the range in which the movement of the elastically deformable cushion 10 and the wire frame 30 is restricted by being hooked on the seat cushion 50. As shown in FIG.

Moreover, the wire frame 30 is easily elastically deformed since buffer portions are provided between the rear hook wires 30d and the rear support wires 30e of the wire frame 30. As shown in FIG. Thereby, the seat cushion 6a can move relatively largely.

Accordingly, the seat cushion 6a also moves appropriately according to the movement of the seated user, so that the user can be comfortably seated.

As shown in FIG. 8B, when the user sits on the seat 11, the seat 11 is compressed. The rear hooking portion 32 is in contact with and supported by the first restricting member 50 , and the front hooking portion 31 is in contact with and supported by the second restricting member 40 .

That is, the cushion 10 and the pad 20 are restricted from moving forward beyond a predetermined amount by the rear hooking portion 32 of the wire frame 30 being received by the first restricting member 50 . The cushion 10 and the pad 20 are restricted from moving backward beyond a predetermined amount by receiving the front hooking portion 31 of the wire frame 30 on the second restricting member 40 .

Further, the cushion 10 and the pad 20 are prevented from tilting forward (tilting so that the front side is displaced downward) more than a predetermined amount by receiving the front engaging portion 31 on the lower restricting portion 40b of the second restricting member 40. Regulated. Further, the cushion 10 and the pad 20 are prevented from tilting backward (tilting so that the front side is displaced upward) more than a predetermined amount by receiving the front engaging portion 31 on the upper restricting portion 40c of the second restricting member 40. It is

A point HP in FIG. 8 indicates the hip point. The hip point HP is an intermediate position between the left and right femoral heads of the seated user. In a normal sitting posture, the hip point HP is preferably positioned at the rear portion of the seat cushion 6a when the seat cushion 6a is divided into front and rear halves. Moreover, it is preferable that the hip point HP is located behind the intermediate position of the pad 20 in the front-rear direction. In particular, the hip point HP is preferably positioned near the rear end of the pad 20 .

Since the user's buttocks are supported by the pad 20 via the thick cushion 10, the user's buttocks do not feel foreign. The user's thighs are supported by the pad 20 via the thin cushion 10, but since the pad 20 moves freely with respect to the floor panel 2c, the user hardly feels a foreign object. Moreover, since the seating surface 21a is positioned under the user's buttocks and thighs, it is even more difficult for the user to feel uncomfortable.

When a vehicle collides or another vehicle collides with the vehicle and a strong forward force acts on the rear seat 6 and the user as indicated by the arrow in FIG. Since forward tilting is regulated by the regulating member 40, the pad 20 and the buttocks do not tilt forward beyond the appropriate range. Therefore, it is possible to prevent the user from sinking forward.

Furthermore, since the wire frame 30 hooked to the pad 20 is hooked to the first restricting member 50, even if the front hooking portion 31 slips forward from the second restricting portion 40, the user can move forward together with the pad 20. You can prevent it from slipping. At this time, the elastic force of the wire frame 30 can gradually reduce the impact, so forward slippage can be suppressed more effectively.

A stronger force acts, and as shown in FIG. 9B, the front side hooking portion 31 is completely disengaged from the second restricting member 40, and the wire frame 30 supported by the first restricting member 50 is fully extended. Even at this time, the pad 20 hooked to the wire frame 30 allows the user to receive it in a well-balanced manner. Therefore, even in such a case, it is possible to suppress forward sliding and forward jumping.

In particular, since the wire frame 30 has a structure in which annular frames are arranged side by side for each seat, the rear seat 6 can be sat by either one person or two people. While ensuring a comfortable sitting experience, it is possible to effectively suppress forward slippage and forward jumping.

Thus, according to the rear seat 6 to which the disclosed technology is applied, it is possible to obtain good sitting comfort and effectively suppress forward slippage.

Note that the vehicle seat according to the disclosed technology is not limited to the above-described embodiments, and includes various other configurations.

For example, vehicles to which the disclosed technology can be applied are not limited to vehicles having wing doors as described above. It is also applicable to vehicles with sliding doors. The technology disclosed is suitable for a horizontally long rear seat on which a plurality of people can sit, but is not limited to the rear seat. It can also be applied to seats where one person sits, such as a driver's seat or an auxiliary seat.
