The present invention relates to a hooking structure for a seat.
A seat bottom or a backrest that constitutes a vehicle seat generally includes a cushion material made of a foam material, a trim cover which covers the cushion material, and the like. Furthermore, a seat further provided with wadding or a removable dressing cover changeable according to a user's preference is also used.
For example, Patent Document 1 proposes a vehicle seat in which a groove part for hooking is formed in a seat cushion body and a cover body is removably provided on the seat cushion body with a slide fastener provided in the groove part. In this specification, one fastener strip of the slide fastener is attached to the side peripheral surface of the seat cushion body and to the groove part formed in the seating surface, while the other fastener strip is attached to the rim of the cover body and to the inner surface part so as to be engageable with one fastener strip (refer to Patent Document 1).
Patent Document 1: Utility Model Application Publication No. H02-141256
The above-described vehicle seat, however, adopts a structure in which a trim cover (cover body) is configured to be fittable or removable so as to dress the seat with a slide fastener that is stitched to the base trim cover (particularly in Patent Document 1, the base trim cover corresponds to a main pad cover which wraps around the seat cushion body and a side pad upper cover which covers the side part of the pad). Therefore, if the slide fastener is broken, the entire base trim cover needs to be replaced, thus increasing the repair cost.
Therefore, an object of the present invention is to provide a hooking structure for a seat that reduces repair cost by enabling a replacement of only a fastening member without a replacement of a base trim cover in the case of breakage of a fastening member for use in fitting and removing a dressing cover.
In order to achieve the object, the present invention provides a hooking structure for a seat in which a dressing cover is hooked to be supported removably from a seat member provided with a base trim cover, including: a fastening member that is configured from an open-type slide fastener and is not stitched to the base trim cover, where the open-type slide fastener includes a fastener part that is formed of one fastener half part and the other fastener half part and a slider part that slides along the fastener part to open and close the one fastener half part and the other fastener half part; and a plastic fixing member that fixes the one fastener half part to the seat member in a groove part for hooking formed in the seat member, wherein: the fastening member is provided with a locked part; the fixing member is provided with a flexible locking part that locks the locked part; and the other fastener half part and the dressing cover are anchored together by an anchoring part.
In this hooking structure, the fastening member is not stitched to the base trim cover and therefore the base trim cover and the fastening member are independent of each other, thus enabling only the fastening member to be replaced by releasing the fixing by the fixing member with the base trim cover left as it is. Therefore, in the case of a broken fastening member, only the fastening member is able to be replaced without a replacement of the base trim cover.
Moreover, the fixing member is made of plastic and has a flexible locking part, and therefore the locked part of the fastening member is able to be unlocked by deflecting and deforming the locking part. The work of deforming the plastic locking part in this manner is able to be carried out with bare hands. Therefore, the hooking structure enables a hooking work or a work of removing the trim cover without using a tool.
Furthermore, the plastic fixing member looks better than a metal fixing member and is less likely to give an uncomfortable feeling.
The locking part of the fixing member may have a pair of locking claws that sandwich the locked part. This type of locking part sandwiches the locked part between the pair of locking claws to hold the locked part with being locked by the locking claws.
Preferably the locked part has a wedge-shaped cross section. Pressing the locked part having the wedge-shaped cross section to the locking part of the fixing member causes the pair of locking claws to be pressed apart, which thereby facilitates the work of pushing and locking the locked part. Furthermore, the locked part is able to be detached from the locking part by turning and rotating the locked part sandwiched between the locking claws and then pulling the tip of the wedge toward between the pair of locking claws.
Preferably, the fixing member has an inclined plane for applying a force of pushing open the pair of locking claws upon pressing of the locked part. Pushing the locked part of the fastening member to the locking part causes the pair of locking claws to be pushed open through the inclined plane, thereby enabling the locked part to be easily pushed into between the pair of locking claws.
The locked part may have a rectangular cross section.
The seat member may be provided inside with an insert member that locks the fixing member and the fixing member may have a fastening part able to be hooked on the insert member. The fastening part enables the fixing member to be locked by hooking the fixing member on the insert member. Moreover, the locked state can be easily released by detaching the fastening part.
The locked part may include a plastic molding product.
The locked part may be formed of a plastic plate integrated into the one fastener half part.
The locked part may be formed of a plastic cord integrated into the one fastener half part.
The locked part may be formed of a plastic cord inserted into the one fastener half part that is sewn into a bag shape.
The locked part may be provided in a joint member that constitutes a part of the one fastener half part.
In the hooking structure, a hole may be formed in the base trim cover so that the fixing member having passed through the hole locks with the insert member.
Furthermore, according to the present invention, there is provided a hooking structure for a seat in which a dressing cover is hooked to be supported removably from a seat member, including: a fastening member that is configured from an open-type slide fastener, where the open-type slide fastener includes a fastener part that is formed of one fastener half part and the other fastener half part and a slider part that slides along the fastener part to open and close the one fastener half part and the other fastener half part; and a plastic fixing member that fixes the one fastener half part to the seat member in a groove part for hooking formed in the seat member, wherein: the fastening member is provided with a locked part; the fixing member is provided with a flexible locking part that locks the locked part; and the other fastener half part and the dressing cover are anchored together by an anchoring part.
In this hooking structure, in the case of breakage of a fastening member for use in fitting and removing the dressing cover, only the fastening member can be replaced, thereby enabling a reduction of repair cost.
The locking part of the fixing member may have a pair of locking claws that sandwich the locked part. This type of locking part sandwiches the locked part between the pair of locking claws to hold the locked part with being locked by the locking claws.
Preferably, the locked part has a wedge-shaped cross section. Pressing the locked part having the wedge-shaped cross section to the locking part of the fixing member causes the pair of locking claws to be pressed apart, which thereby facilitates the work of pushing and locking the locked part. Furthermore, the locked part can be detached from the locking part by turning and rotating the locked part sandwiched between the locking claws and pulling the tip of the wedge toward between the pair of locking claws.
Preferably, the fixing member has an inclined plane for applying a force of pushing open the pair of locking claws upon pressing of the locked part. Pushing the locked part of the fastening member to the locking part causes the pair of locking claws to be pushed open through the inclined plane, thereby enabling the locked part to be easily pushed into between the pair of locking claws.
The locked part may have a rectangular cross section.
The seat member may be provided inside with an insert member that locks the fixing member and the fixing member may have a fastening part able to be hooked on the insert member. The fastening part enables the fixing member to be locked by hooking the fixing member on the insert member. Moreover, the locked state can be easily released by detaching the fastening part.

Hereinafter, detailed description will be made on preferable embodiments of a hooking structure for a seat according to the present invention with reference to drawings (see
A seat 1 includes a seat bottom 2 movable back and forth on a floor panel of a vehicle and a backrest 3 capable of reclining to the seat bottom 2. The seat bottom 2 and the backrest 3 are seat members that constitute the seat 1 and each include a cushion material 4 made of foam. Moreover, a dressing cover 7 is fittable or removable to or from the seat bottom 2 and the backrest 3 by using a hooking structure 10. The seat bottom 2 and the backrest 3 are provided with a plurality of linear hooking grooves 11 that constitute the hooking structure 10 (see
A description will now be made by giving an example of the backrest 3. The cushion material 4 constituting the backrest 3 has a main cushion part 41 for use in supporting the back of an occupant from the rear and a side cushion part 42 for use in holding the back of the occupant from the side (see
The dressing cover 7 is formed of a main surface part 71 placed on the main cushion part 41 of the cushion material 4 and a side surface part 72 placed on the side cushion part 42 (see
Furthermore, the dressing cover 7, which is hooked to be supported in the hooking groove 11 by using the fastening member 5, is attached to the backrest 3 or the seat bottom 2 at its outer periphery by the outer-periphery dressing fastener 8. In the present specification and drawings, only the arrangement example of the outer-periphery dressing fastener 8 is illustrated (see
The hooking structure 10 for hooking and supporting the dressing cover 7 includes the fastening member 5, the hooking groove 11, an insert wire 16, and a plastic fixing clip (fixing member) 30 (see
The hooking groove 11 is formed of a concave portion 12, which is formed with a predetermined depth in a vertical direction of the backrest 2 along the boundary between the main cushion part 41 and the side cushion part 42. The hooking groove 11 forms an appearance of the seat 1 and stores a base-side tape part (one fastener half part) 511 of the fastening member 5, which is used for hooking the dressing cover 7. Although the concave portion 12 is compressed and closed between the main cushion part 41 and the side cushion part 42 by elasticity of the cushion material 4 in the normal state,
Although the backrest 3 is further provided with a hooking groove 11 extending in a horizontal direction (in a width direction of the backrest 3) in addition to the aforementioned hooking groove 11, and the seat bottom 2 is also provided with a hooking groove 11 (see
The fastening member 5 is a member that enables the dressing cover 7 to be fitted or removed in the hooking groove 11 formed in the cushion material 4. The fastening member 5 of the present embodiment is formed of a slide fastener 50 including a fastener part 51 and a slider part 52 (see
The fastener part 51 of the slide fastener 50 includes the base-side tape part 511 and the cover-side tape part 512. The base-side tape part 511 and the cover-side tape part 512 include elements (teeth) 511B and 512B engaging with each other and insert pins (only an insert pin 512C of the cover-side tape part 512 is illustrated in
The slider part 52 of the slide fastener 50 slides on the fastener part 51 in the direction in which the elements 511B and 512B are aligned (hereinafter, the direction will be referred to as “slide direction” and indicated by character S), so that the element 511B of the base-side tape part 511 engages with the element 512B of the cover-side tape part 512 to fasten the fastening member 5 or so that the engagement is released so as to release the fastening of the fastening member 5.
The cover-side tape part 512 is stitched together with the main surface part 71 and the side surface part 72 of the dressing cover 7 in the stitched part 74 and anchored to the dressing cover 7 (see
A locked part 53 is formed at the edge of the base-side tape part 511. The locked part 53 has an enough width that the locked part 53 is locked with the locking part 31 of the plastic clip 30 (see
Although a specific configuration of the locked part 53 is not particularly limited, the locked part 53 may include a plastic molding product. For example, the locked part 53 may be configured by sewing a plate-like plastic plate 53A on the edge of the base-side tape part 511 so as to be integrated into the base-side tape part 511 (see
In another example, the locked part 53 may be formed of a plastic cord 53B that has been molded along the edge of the base-side tape part 511 (see
In still another example, the end of the base-side tape part 511 is sewn into a bag shape to form a loop 511L and then the plastic cord 53B is inserted into the loop 511L, thereby enabling the configuration of the locked part 53 (see
The insert wire 16 is buried inside the cushion material 4 of the backrest 2 and in a portion at a predetermined depth from the bottom of the concave portion 12 (see
Although a specific shape of the insert wire 16 is not illustrated in the diagram, the insert wire 16 may be a wire that extends straight in a direction in which the concave portion 12 is formed (in the present embodiment, the vertical direction along the boundary between the main cushion part 41 and the side cushion part 42) or may be a wire in which a portion to which the plastic clip 30 is fixed is cranked so as to be closer to the concave portion 12. In addition, both ends of the insert wire 16 are bent and rounded.
The plastic clip 30 is a fixing member that is used to fix the base-side tape part 511 of the fastening member 5 to the seat member in the hooking groove 11 and has a locking part 31 and a fastening part 32 (see
The locking part 31 is a portion that is used to lock the locked part 53 of the fastening member 5 and is flexible. The locking part 31 of the plastic clip 30 according to the present embodiment has a pair of locking claws (locking pieces) 31A facing each other and sandwiches the locked part 53 with the pair of locking claws 31A to hold the locked part 53 (see
Furthermore, on the back side (a portion facing outward) of each locking claw 31A of the locking part 31, there is formed an inclined plane 31B to which a force of pushing open the pair of locking claws 31A is applied when the locked part 53 is pressed (see
The fastening part 32 of the plastic clip 30 is a portion that hooks and locks the insert wire 16. The fastening part 32 of the plastic clip 30 according to the present embodiment is hook-shaped so as to be able to hook the insert wire 16 (see
Moreover, a hole 65 is formed in the base trim cover 6, so that the plastic clip 30 locks the insert wire 16 through the hole 65 (see
Other hooking grooves 11 of the backrest 3 and other hooking grooves 11 in the seat bottom 2, and a hooking structure 10 formed by each of the hooking grooves are configured in the same manner as the above-described hooking structure 10. Therefore, their description will be omitted here.
In the hooking structure 10 for the seat 1 according to the present embodiment described hereinabove, the fastening member 5 is not stitched to the base trim cover 6 (in other words, the plastic clip 30, which fixes [the base-side tape part 511 of] the fastening member 5 to the cushion material 4, merely penetrates the base trim cover 6), and therefore the base trim cover 6 and the fastening member 5 are independent of each other and can be separated from each other. Therefore, if the fastening member 5 is broken, it is possible to detach the plastic clip 30 to release the fixing and to detach only the fastening member 5 for replacement with the base trim cover 6 left as it is. In other words, since only the fastening member 5 is able to be replaced without replacement of the base trim cover 6, the repair cost required in the case of breakage of the fastening member 5 can be reduced.
Furthermore, in this hooking structure 10, a metal fixing member, which requires a dedicated attachment tool, is not used, but instead, the plastic clip 30, which enables a hooking work with bare hands, is used as the fixing member, and therefore no tool need not be used. This prevents a case of failure in handling or a problem caused thereby that could have occurred in the case where an inexperienced worker uses a tool. Moreover, the hooking work with the plastic clip 30 is composed of relatively simple works such as causing the locking part 31 to lock with the locked part 53 of the fastening member 5 and hooking the fastening part 32 on the insert wire 16, thereby not requiring high proficiency.
The following briefly describes a procedure for hooking the dressing cover 7 in the aforementioned hooking structure 10.
The plastic clip 30 is attached at a predetermined place of the locked part 53 of the fastening member 5 (see
Subsequently, the fastening part 32 of the plastic clip 30 is allowed to pass through the hole 65 of the base trim cover 6 and then is hooked on the insert wire 16 (see
Similarly, in other predetermined places, the fastening member 5 is fastened to the insert wire 16 with the plastic clip 30. As described above, the fastening member 5 is able to be hooked into the hooking groove 11 together with a part of the dressing cover 7 (see
Additionally, hooking the dressing cover 7 into the hooking groove 11 requires both of the work of locking the locked part 53 of the fastening member 5 with the locking part 31 of the plastic clip 30 and the work of hooking the fastening part of the plastic clip 30 on the insert wire 16 as described above. Note that, however, the order of the works is not particularly limited, but either of the works may precede the other.
Moreover, to detach the fastening member 5 from the cushion material 4, the following work is required.
Specifically, fingers are inserted into the hooking groove 11 to pick the plastic plate 53A up with the fingers in the vicinity of the plastic clip 30 and then to give a twist to and rotate the plastic plate 53A (see
Furthermore, in the case where the locked part 53 is composed of a plastic cord 53B having a wedge-shaped cross section (see
Furthermore, in the case where the plastic cord 53B is inserted into the loop 511L of the base-side tape part 511 (see
As described above, the fixing member in the hooking structure 10 according to the present embodiment is the plastic clip 30 and has the flexible locking part 31. Therefore, the locked part 53 of the fastening member 5 is able to be unlocked by deflecting and deforming the locking part 31. The work of deforming the plastic locking part 31 in this manner is able to be performed with bare hands, which enables a hooking work or a work of detaching the fastening member 5 without using a tool.
Although the above embodiments are merely preferred embodiments of the present invention, the present invention is not limited thereto, but various modifications can be made without departing from the scope and principles of the present invention. For example, the seat 1 to which the hooking structure 10 according to the present invention is applied can be used for an automotive seat, an aircraft seat, a passenger ship seat, a railway vehicle seat, and the like.
Furthermore, the provision of the insert member such as the insert wire 16 in the cushion material 4 as described above preferably alleviates local deformation of the cushion material 4 in the hooking structure 10 and makes it difficult for the plastic clip 30 to move or come off. If, however, the plastic clip 30 can be firmly fixed only with the use of the cushion material 4, the insert member need not necessarily be provided.
Furthermore, while the above embodiments illustrate the cases where the surface of the cushion material 4 is coated with the base trim cover 6 by using, for example, an adhesive or integral foam molding (see
Furthermore, the present invention is also applicable to the hooking structure 10 for the seat 1 not provided with the base trim cover 6 (see
Although the hooking structure 10 in which the locked part 53 is formed at the edge of the base-side tape part 511 has been illustrated in the above embodiments, it is a merely preferred example in the case of providing the locked part 53 in the fastening member 5. Specifically, the locked part 53 may be directly formed in a part of the base-side tape part 511 (see
Furthermore, in the structure in which the locked part 53 is previously plastic-molded in the suspender 511S in this manner, a long locked part 53 is previously plastic-molded in a long suspender 511S whose detailed size is not determined, so that the suspender 511S can be cut into a predetermined length and used. According thereto, the present invention is able to easily cope with various lengths of products and thus increases the versatility. In addition, it eliminates the necessity of separately making molds in plastic molding, thereby also having a cost advantage.
Although not specifically illustrated, the suspender 511S may be combined with the embodiment in which the locked part 53 is configured by forming the loop 511L by sewing the end of the base-side tape part 511 into a bag shape and inserting the plastic cord 53B into the loop 511L (see
The present invention is preferably applied to a hooking structure for a seat in which a dressing cover is fittable or removable to or from the seat member with a base trim cover.
