Abstract

When a front panel is swung upward by a tilt mechanism, a gap is created between the front part of a seat pad and a front cover, and the inside of the seat cushion is visible through the gap, impairing design and appearance and creating a possibility that a finger, etc. are caught in the gap. In order to prevent such a situation, a first clip, one end (upper end) of which is mounted to the front panel, a cover body, one end (upper end) of which is connected to the other end (lower end) of the first clip and to the front end of a trim cover, an elastic body, one end (upper end) of which is connected to the other end (lower end) of the cover body, and a second clip, one end of which is connected to the other end (lower end) of the elastic body, are provided between the front end of the front panel and the front end of a seat cushion frame. The other end of the second clip is connected to the seat cushion frame. When the front panel is swung upward, the elastic body is extended and the cover body covers and hides the gap between the front end of the seat pad and the front cover.

Description

Seat cushion structure for vehicle seat

The present invention relates to a seat cushion structure for a vehicle seat having a tilt mechanism at a front portion thereof.

A vehicle seat includes a seat back and a seat cushion, and each seat back and seat cushion has a seat pad made of a foam molding material such as urethane foam on a frame (seat back frame, seat cushion frame) as a skeleton, Each seat cover is formed by a breathable trim cover.

Specifically, the seat cushion frame (seat cushion frame) includes a pair of left and right side frames, a front frame, and a rear frame, and is configured in a substantially rectangular shape.

In addition, the seat cushion frame further includes a front panel that covers the upper front portion of the front frame. The front panel has, for example, a plate portion having a flat plate shape and a pair of left and right arms. The plate portion supports the front bottom surface of the seat pad and is positioned above the front frame to cover and hide the front frame. Further, the plate portion supports the front bottom surface of the seat pad from below.

The pair of left and right arms extends rearward from the left and right rear ends of the plate portion, and is axially connected to the center portion of each side frame in the front-rear direction by a swing shaft (pin). Therefore, the front panel can swing up and down around the swing axis.

An electric tilt mechanism for adjusting the swing angle of the front panel is provided at the front portion of the seat cushion. When the tilt mechanism is operated, the front panel swings (lifts) around the swing shaft while supporting the front bottom surface of the seat pad from below, and is fixed and held at a preferred swing angle. By such a tilt mechanism, the angle of the front panel that supports the thigh of the seat cushion occupant can be freely adjusted (for example, Japanese Patent Application No. 2015-223851).

Further, the seat pad placed on the front panel is covered with a trim cover that is extended so as not to be loose. The front end of the trim cover is stitched to a clip formed of, for example, a soft plastic and attached to the front end of the front panel via the clip (for example, Japanese Patent Application No. 2011-156994).

Japanese Patent Application No. 2015-223851 Japanese Patent Application No. 2011-156994

By the way, the front frame and the pair of left and right side frames of the seat cushion frame are respectively covered from the outside with a resin cover called a front cover and a pair of left and right side covers from the front and left and right sides. When the front panel is positioned substantially horizontally with respect to the seat cushion frame, that is, when the tilt mechanism does not operate and the angle of the front panel is not adjusted, the seat cushion frame and front panel have the seat pad on the top and the front The front cover and the left and right side surfaces are covered with the left and right side covers, respectively, and are not visible from these directions.

However, when the front panel swings upward by the tilt mechanism and the front part of the seat pad is lifted, a gap is generated between the front part (front panel) of the seat pad and the front cover. If the inside of the seat cushion frame, the front panel, etc. is visually recognized from this gap, the appearance quality of the seat may be deteriorated.

Moreover, there is an undeniable risk that a finger of a seated person's hand, a hem of clothes, or the like may be caught in the gap between the front part of the seat pad and the front cover.

If you lower the front lower end of the seat pad of the seat cushion and form a gap between the front part of the seat pad and the front cover from the front, it will be extended even if the front panel swings upward. The lower front edge of the seat pad covers this gap from the front. Therefore, the seat cushion frame and the front panel are not visually recognized.

However, even if the front panel swings, to ensure that the lower front edge of the seat pad always covers the gap, the lower front edge of the seat pad must be formed along the swing path of the seat pad (front panel). I must. Therefore, there is a possibility that the degree of freedom of design in the shape of the front surface of the seat pad is limited.

In the configuration described in Japanese Patent Application No. 2011-156994, the front end of the trim cover is attached to the front end of the front panel and does not extend to the front cover. Therefore, the trim cover does not cover the gap between the front portion of the seat pad and the front cover.

If the front end of the trim cover is extended downward and attached to the front cover, the gap between the front portion of the seat pad and the front cover is covered with the trim cover even if the front panel swings. Therefore, the seat cushion frame or the like is not visually recognized from the gap.

However, when the front panel is positioned substantially horizontally with respect to the seat cushion frame, the trim cover is loosened forward and the appearance quality of the trim cover is degraded.

The present invention not only does not impair the appearance quality and the degree of design freedom, but also prevents the front part of the seat pad and the gap between the front covers from being visually recognized or the fingers of the seated person from being caught. An object of the present invention is to provide a simple seat cushion structure for a vehicle seat.

In the present invention, a shield is provided in the gap between the front portion of the seat pad and the front cover, and the shield covers and covers this gap.

That is, according to the first aspect of the present invention, the front cover that supports the trim cover that covers the seat pad, the front bottom surface of the seat pad, and is swung vertically by the tilt mechanism to lift the front bottom portion of the seat pad. In a seat cushion structure for a vehicle seat comprising a panel and a seat cushion frame on which a front panel is placed on the front, one end of the seat cushion structure is attached to the front end of the front panel and the other end is connected to the front end of the trim cover. 1, a second clip having one end connected to the front end of the seat cushion frame located below, an elastic body having one end connected to the other end of the second clip, and one end being the first The shield, which is connected to the clip and the trim cover, and whose other end extends downward and is connected to the other end of the elastic body, Of the front end, it is provided between the front end of the seat cushion frame.

In the first aspect of the present invention, even when the tilt mechanism is activated and the front panel swings upward, the shield covers the gap between the front portion of the seat pad and the front cover. Therefore, the inside of the seat cushion is not visually recognized from this gap. Further, the appearance quality of the seat cushion is not impaired by visually recognizing the inside of the seat cushion. Further, fingers of the seated person's hand and the like are not caught in the gap between the front part of the seat pad and the front cover.

Then, the first clip is attached to the front end of the front panel of the seat cushion, the shield, the elastic body, and the second clip are connected in order from the lower end of the first clip, and the second clip is connected to the seat cushion frame. It is enough to make it. This simplifies the configuration and does not impair the degree of design freedom.

The perspective view of the vehicular seat provided with the seat cushion structure concerning one example of the present invention is shown. The disassembled perspective view of the vehicle seat provided with the seat cushion structure which concerns on one Example of this invention is shown. In FIG. 2, only the frame of the seat back is shown in order to avoid complication of the drawing. The perspective view of a seat cushion frame is shown.

FIG. 1 is a perspective view of a vehicle seat having a seat cushion structure according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the vehicle seat having a seat cushion structure according to an embodiment of the present invention. In FIG. 2, only the frame of the seat back is shown in order to avoid complication of the drawing.

Front, back, top, bottom, left and right refer to the direction viewed from the driver seated on the driver seat, and are indicated by Fr, Rr, Up, Lw, L, and R.

As shown in FIGS. 1 and 2, the vehicle seat 10 includes a seat back 20 and a seat cushion 30 having a rear end coupled to a lower end of the seat back and is disposed on a vehicle floor (not shown). .

For example, the fixed rail of the slide rail device 40, that is, the lower rail 40a is bolted to the vehicle floor using a bracket. In addition, a cushion frame of a seat cushion, which will be described later, is disposed on the movable rail, that is, the upper rail 40b, so that the seat 10 is movable in the front-rear direction.

The seat cushion 30 is formed by placing a seat pad 34 made of a foam molding material such as urethane foam on a frame (seat cushion frame 32) serving as a skeleton and covering the seat pad with a breathable trim cover 36. The trim cover is made of a material such as non-woven fabric, leather, or synthetic leather.

FIG. 3 shows a perspective view of the seat cushion frame. In FIG. 3, the front panel is omitted in order to avoid complication of the drawing.

The frame (seat cushion frame 32) of the seat cushion 30 is configured as follows, for example. As can be seen from FIG. 3 in conjunction with FIG. 2, the seat cushion frame 32 has a pair of left and right side frames 32L, 32R, a front frame 32Fr, and a rear frame 32Rr, and is formed in a substantially rectangular shape. ing. In the embodiment, the front frame 32Fr and the rear frame 32Rr are both hollow connecting rods (front rods, rear rods) made of steel pipes, the front rods at the front ends of the left and right side frames 32L, 32R, and the rear rods at the left and right sides. Each is connected to the rear end of the frame. The left and right side frames 32L and 32R are formed, for example, by pressing a steel plate. Here, the front frame 32Fr is rotatably supported by the left and right side frames 32L and 32R.

As can be seen from FIG. 2 in addition to FIG. 3, the engaging member 32a is provided at the front end of the seat cushion frame 32, for example, between the side frames 32L and 32R in the left-right direction. In FIG. 2, the engaging member 32 a is a wire laid on the front end of the seat cushion frame 32, but is not limited thereto, and may be a bracket provided on the seat cushion frame, for example.

Although details are omitted, the seat back 20 is also configured by placing a seat pad (not shown) on a substantially rectangular seat back frame 22 and covering the seat pad with a trim cover (not shown), like the seat cushion 30. ing.

The seat cushion frame 32 further has a front panel 38 at the front thereof. The front panel 38 is formed by pressing a steel plate so as to have a plate portion 38a and a pair of left and right arms 38b (38b-L, 38b-R). In the embodiment, the plate portion 38a has a flat plate shape having an L-shaped cross section in which an upright wall 38a ′ rises from the front edge. The pair of left and right arms 38b (38b-L, 38b-R) are formed integrally with the upright wall 38a 'of the plate portion and extend rearward from the left and right ends of the upright wall.

The plate portion 38a is positioned above the front frame 32Fr and is laid between the front portions of the left and right side frames 32L and 32R. That is, the front panel 38 is placed on the front portions of the seat cushion frames 32L and 32R. The seat pad 34 of the seat cushion is placed on the plate portion 38a.

That is, in the front part of the seat cushion, the seat pad 34, the plate part 38a, and the front frame 32Fr are stacked in this order from the top. The plate part covers the front frame from above and supports the bottom surface of the front part of the seat pad from below. ing.

The pair of left and right arms 38b have their rear portions axially connected to the center portion in the front-rear direction of each side frame by a swing shaft (pin) 38b '. Therefore, the front panel 38 is attached to the left and right side frames 32L and 32R so as to be swingable in the vertical direction about the swing shaft 38b ′. That is, the front portion of the seat pad 34 supported by the plate portion 38a can swing in the vertical direction by swinging the front panel 38.

The tilt mechanism 39 is not a main part of the present invention, and since its configuration is well known, it will be briefly described.

The tilt mechanism 39 includes a drive device (motor) 39a, a sector gear 39b, and a tilt link 39c. The drive device 39a has a pinion gear (not shown) fixed to the drive shaft. The end of the sector gear 39b is fixed to the front frame 32Fr, and the pinion gear meshes with the teeth at the tip. The tilt link 39c is supported by a bracket 39c ', and the lower end of the bracket is wound around the front peripheral surface of the front frame 32Fr and welded to the front frame. The front end of the tilt link 39c is attached to the bottom surface of the front panel 38.

In this manner, the sector gear 39b, the front frame 32Fr, the bracket 39c ′, and the tilt link 39c are integrally structured, and the tilt link is connected to the front panel 38.

When the tilt mechanism 39 is not operated (normal time), the front panel 38 is positioned substantially horizontally with respect to the vehicle floor.

When the seating mechanism switches the tilt mechanism 39 to drive the drive device 39a, the pinion gear (not shown) rotates, and the sector gear 39b meshing with the pinion gear swings about the central axis of the front frame 32Fr. For example, when the sector gear 39b swings downward, the front frame 32Fr rotates in conjunction with the sector gear and the tilt link 39c swings upward. Accordingly, the front panel 38 swings (lifts) around the swing shaft 38b ′ while supporting the front portion of the seat pad 34 from below.

An arcuate guide hole 39b-1 centering on the central axis of the front frame 32Fr is formed in the sector gear 39b. A guide pin 39b-2 is implanted in the side frame 32L and is inserted through the guide hole. Therefore, the sector gear 39b can be reliably rocked by being guided by the guide pin.

When the seat pad 34 is lifted to the swinging angle (height) desired by the seated person, the seated person operates the tilt mechanism 39 so as to stop the swinging of the front panel 38. As a result, the drive of the driving device 39a is stopped, and the sector gear 39b is fixed, so that the preferred swing angle of the front panel is maintained and fixed.

In this manner, the front panel 38 is swung vertically by the tilt mechanism 39, and the angle of the front portion of the seat pad 34 that supports the thigh of the seated person can be freely adjusted.

As can be seen from FIG. 2, the seat cushion frame 32 further includes a cover 50. The cover 50 includes a front cover 50Fr that covers the seat cushion frame 32 from the front, and a pair of left and right side covers 50S that covers the side. The front cover 50Fr and the side cover 50S are formed in shapes that cover the front and side portions of the seat cushion 30, respectively. The front cover 50Fr and the side cover 50S are molded from a resin such as rigid fiber reinforced plastic (FRP), for example.

In FIG. 2, only the left side cover 50S is shown, and the right side cover is omitted. The right side cover 50S is formed in a symmetrical shape with the left side cover in FIG.

The front cover 50Fr and the pair of left and right side covers 50S are attached to the front and left and right sides of the seat cushion frame, respectively. For example, a pair of left and right mounting members 52Fr is provided on the front portion of the seat cushion frame 32, and a mounting member 52S is provided on the left side of the front portion. The front cover 50Fr is fixed to the front mounting member 52Fr of the seat cushion, and the side cover 50S is fixed to the front left end mounting member 52S with pins (screws). Further, a claw (not shown) is formed on the inner surface of the side cover 50S, and an engagement hole (not shown) corresponding to the claw is formed in the seat cushion frame 32 (left side frame 32L), and the claw is engaged with the engagement hole. By doing so, the side cover 50S is fixed to the seat cushion frame 32 (left side frame 32L). The side cover 50S may be fixed to the seat cushion frame 32 with a configuration other than the combination of the claw and the engagement hole.

4A shows a normal state in which the front panel is positioned substantially horizontally with respect to the seat cushion frame, and FIG. 4B shows a state in which the front panel is swung upward by the tilt mechanism. A longitudinal section view of the front part of the seat cushion along line 4-4 is shown respectively.

2 and 4, the first clip 60-1 is provided at the front end of the front panel 38, and the second clip 60- is provided at the front end of the seat cushion frame 32 (for example, an engaging member (wire) 32a described later). 2 are connected to each other, and a shield 62 and an elastic body 64 are provided between the first clip and the second clip.

The first and second clips 60-1 and 60-2 are formed from, for example, soft plastic.

The first clip 60-1 is a hook-shaped clip that is long in the left-right direction (width direction), and the length in the left-right direction is substantially the same as the length (width) in the left-right direction of the front panel 38. The

As can be seen from FIG. 4, one end (lower end) 60-1a of the first clip 60-1 is folded back upward, and the front end of the front panel 38 is sandwiched inside the folded portion, thereby Attached to the front end.

Specifically, a convex portion 60-1 ′ is formed inside the folded back of the first clip 60-1. The front end of the front panel 38 is also folded upward to form a bent portion 38c. When the front end of the front panel 38 is inserted into the folded inside of the first clip 60-1, the convex portion 60-1 ′ abuts against the bent portion 38c at the front end of the front panel, and the convex portion and the folded back One end 60-1a of the end of one clip holds the front end of the front panel 38. Therefore, attachment of the first clip 60-1 to the front end of the front panel is further ensured.

The shield 62 is a belt-like body formed of the same material as that of the trim cover 36 such as a nonwoven fabric. As can be seen from FIG. 2, the length of the shield 62 in the left-right direction corresponds to the length (width) of the first clip 60-1 in the left-right direction and is substantially the same.

One end (upper end) 62a of the shield is sandwiched between the other end 60-1b of the first clip and the front end 36a of the trim cover, and each end of the first clip 60-1, the shield 62, and the trim cover 36 is sewn. Connected.

As can be seen from FIGS. 4A and 4B, the other end 60-1b of the first clip, one end (upper end) 62a of the shield, and the stitched portion 70 of the front end 36a of the trim cover are seat cushion seats. It is located in a space 34 a between the front bottom surface of the pad 34 and the front end of the front panel 38. Therefore, the stitching portion 70 is hidden on the front bottom surface of the seat pad 34 and is not visually recognized from the front.

The elastic body 64 is a band-shaped body formed from an elastic material such as rubber, for example. In FIG. 2, one elastic body 64 is provided at the central portion in the left-right direction of the shield 62. One end (upper end) 64a of the elastic body is connected to the other end 62b of the shielding body by stitching, and a stitched portion 72 is formed.

The other end (lower end) 64b of the elastic body extends downward and is connected to the second clip 60-2 by stitching to form a stitched portion 74.

Similarly to the first clip 60-1, the second clip 60-2 has a hook shape, for example. In FIG. 2, the number of the second clip 60-2 is only one. However, like the elastic body 64, the second clip 60-2 is not limited thereto, and a plurality of the second clips 60-2 may be provided. As described above, the number of combinations of the elastic body 64 and the second clip 60-2 is not limited to one, and a plurality of combinations may be provided. Further, these positions are also provided only in the central portion of the length in the left-right direction of the shield. It is not limited.

4A and 4B, the second clip 60-2 is engaged with an engagement member (wire) 32a extending forward from the seat cushion frame 32. It is not limited to the configuration. Of course, a bracket may be provided at the front end of the seat cushion frame 32, and the second clip 60-2 may be engaged with the bracket. Alternatively, for example, an engagement hole (not shown) for engaging the second clip 60-2 may be provided on the front surface of the seat cushion frame 32, and the second clip may be directly engaged with the seat cushion frame.

As shown in FIGS. 4A and 4B, the front cover 50Fr covers the seat cushion frame 32 from the front with the elastic body 64 and the second clip 60-2 covered from the front. Is provided.

The operation for swinging the front part of the seat pad 34 upward (when swinging) will be described.

When the tilt mechanism 39 is switched by a seated person, a pinion gear (not shown) is rotated by driving of the driving device 39a, and the sector gear 39b meshing with the pinion gear swings downward about the central axis of the front frame 32Fr. Rotate the front frame. Then, the tilt link 39c attached to the front frame 32Fr is swung upward, and the front panel 38 supports the front portion of the seat pad 34 from below, and the swing shaft 38b ′ is used as a center in FIG. Is swung (lifted) in the direction of the arrow.

At this time, as shown in FIG. 4B, a gap X is generated between the front portion of the seat pad 34 and the front cover 50Fr.

When the front portion (front panel 38) of the seat pad 34 is swung upward, the shield 62 is lifted upward via the first clip 60-1 to cover the gap X. Even if the front part (front panel 38) of the seat pad 34 is further swung upward, the elastic body 64 connected to the other end (lower end) 62b of the shield is extended upward by the elastic force, and the shield The state of 62, that is, the state where the shield covers the gap X is maintained.

Since the shield 62 covers the gap X, the seat cushion frame 32 or the like inside the seat cushion is not visually recognized from this gap, that is, from the front of the seat cushion 30. Further, the appearance quality of the seat cushion is not impaired by visually recognizing the inside of the seat cushion 30 from the gap X. Further, fingers of the seated person's hand or the like are not caught in the gap X.

Even if the front portion (front panel 38) of the seat pad 34 is further swung upward and the gap X is enlarged, the elastic body 64 is extended upward by the elastic force, and the shielding body is opened in the gap X. Maintain the state of covering. Therefore, even if the gap X is enlarged, the inside of the seat cushion 30 is not visually recognized from the gap X.

As shown in FIG. 2, the seat pad 34 has a convex portion 34b that protrudes downward at the front side end. The pair of left and right side panels 50S has a curved portion 50Sa curved inward at the front. Therefore, the convex part 34b on the front side surface of the seat pad and the front side surface 50Sa of the side cover of the seat cushion are covered and hidden, and the side gap is not visually recognized. Of course, the shield 62 may be formed into a shape having curved pieces that are curved inwardly at the left and right edges. If it is this shape, visual recognition of the side gap can be prevented by the left and right curved pieces.

The shield 62 has one end (upper end) 62a on the front panel 38 via the first clip 60-1, and the other end (lower end) 62b on the elastic body 64 and the seat clip via the second clip 60-2. It is connected to a frame 32 (for example, an engaging member (wire) 32a). That is, only the first clip 60-1, the shield 62, the elastic body 64, and the second clip 60-2 are provided between the front portion (front panel 38) of the seat pad 34 and the seat cushion frame 32. Can cover the gap X, and the configuration becomes simple. Further, the first clip 60-1 can be connected to the front panel 38 and the second clip 60-2 can be connected simply by engaging with the seat cushion frame 32, and can be easily connected.

Further, the first and second clips 60-1, 60-2 are soft plastic, the shield 62 is the same material as the trim cover 36 (for example, non-woven fabric, leather, synthetic leather, etc.), and the elastic body 64 is elastic such as rubber. Since it is formed from a material and can be sewn, it can be easily connected by suturing.

Specifically, the other end 60-1b of the first clip, one end (upper end) 62a of the shield, and the front end 36a of the trim cover are connected by stitching (sewn portion 70). Further, one end 64a of the elastic body is connected to the other end (lower end) 62b of the shielding body by stitching (sewn portion 72). Further, the other end 64b of the elastic body is connected to the second clip 60-2 by stitching (stitching portion 74).

The shield 62 has one end (upper end) 62a connected to the front panel 38 via the first clip 60-1, and the other end (lower end) 62b connected to the elastic body 64. Therefore, even if the front panel 38 swings in the vertical direction, the elastic body 64 expands and contracts due to the elastic force, so that the shielding body 62 does not loosen.

The configuration of the present invention in which the gap X is covered by the shielding body 62 is configured so that the lower end of the front surface of the seat pad 34 extends downward and the lower end of the front surface of the seat pad is swung in comparison with the configuration in which the gap X is covered. It is not necessary to form so that it may follow. That is, it is not necessary to change the shape of the front surface of the seat pad 34, and there is no possibility that the degree of freedom of the shape of the front surface of the seat pad is limited.

The elastic body 64 and the second clip 60-2 are covered and concealed from the front by the front cover 50Fr together with the seat cushion frame 32 (the engaging member (wire) 32a thereof). Therefore, the appearance quality of the seat cushion 30 is not deteriorated by visually recognizing the elastic body 64 or the like.

Further, for example, the shield 62 is made of the same material as that of the trim cover 36, and the elastic body 64 is made of an elastic material such as rubber. It is done.

Since the engagement member 32a is provided at the front end of the seat cushion frame 32, the shield 62 and the elastic body 64 can be easily connected to the cushion frame by engaging the second clip 60-2 with the engagement member.

Further, if the length of the first clip 60-1 in the left-right direction corresponds to the length of the front panel 38 in the left-right direction, the first clip is securely engaged and connected to the front panel in the left-right direction. The Then, if the length in the left-right direction of the shield 62 is made to correspond to the length in the left-right direction of the front panel 38 (first clip 60-1), the shield reliably engages and connects with the first clip. In addition, the gap X between the front portion of the seat pad 34 and the front cover 50Fr can be widely covered in the left-right direction.

The elastic body 64 and the second clip 60-2 need only be provided at the center in the left-right direction of the shield 62, and the configuration is simple. The configuration is not limited to this, and a plurality of combinations of the elastic body 64 and the second clip 60-2 may be provided.
