Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cover mounting structure for a vehicle seat.
[0002]
[Prior art]
Generally, a vehicle seat has a structure in which a pad having cushioning properties is covered with a cover. Conventionally, in order to prevent the cover from being lifted or displaced from the pad, an attachment piece (for example, a bag shape) provided on the back surface of the cover is drawn into a groove formed on the surface of the pad, The tip of the mounting piece was hooked with a metal clip using a dedicated tool against the wire embedded in the pad.
[0003]
In such a hook ring connection using a metal clip, it is difficult to remove the cover when the vehicle is dismantled or the like. Recently, “easy dismantling recycling (meaning shortening of dismantling time and enabling recycling)” In view of the above, there has been proposed a structure in which a cover and a pad are attached by a pair of surface fasteners without using a metal clip (see Utility Model Registration No. 2559038 as a similar technique). That is, one surface fastener is provided on the bottom surface of the groove portion of the pad, and the other surface fastener is provided on the mounting piece of the cover, and both the surface fasteners are joined to each other to attach the cover to the surface of the pad. . With such an attachment structure, even when the vehicle seat is disassembled, the cover can be easily removed, and the cover and the pad can be easily recycled.
[0004]
[Problems to be solved by the invention]
However, in such a conventional technique, although easy disassembly and recyclability are satisfied, there is a risk that the mounting strength of the cover may be lowered depending on how the load is applied to the hook-and-loop fastener. In other words, when a peeling load is applied to the entire surface fastener, a large bonding strength is exhibited. However, when the peeling load is applied to the longitudinal end portion of the surface fastener, each engagement is sequentially peeled from the end portion. Thus, the bonding strength as a surface fastener is low, and the attachment strength of the cover to the pad is reduced.
[0005]
The present invention has been made paying attention to such a conventional technique, and provides a cover mounting structure for a vehicle seat that can prevent a peeling load from being applied to the longitudinal end portion of the surface fastener. It is.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, one surface fastener is provided on the bottom surface of the groove portion having a predetermined length formed on the surface of the pad, and the other mounting piece is formed on a portion corresponding to the groove portion on the back surface of the cover. In a vehicle seat cover mounting structure in which a surface fastener is provided and both the surface fasteners are joined to each other to attach the cover to the surface of the pad, the other surface fastener sews in a state of covering the tip of the cover mounting piece. In this case, an unsewn portion is provided at the longitudinal end of the other surface fastener .
[0009]
According to the invention described in claim 1, the longitudinal end portion of the other surface fastener, since the sewn portions are provided, even if joined by peeling load in the cover, the peeling load of the fastener longitudinal direction It acts on the position shifted inward by the length of the non-sewn part, not added to the end. Accordingly, the joining strength of the surface fastener is improved, and the mounting strength of the cover is increased.
[0010]
According to the second aspect of the present invention , one surface fastener is provided on the bottom surface of the groove portion having a predetermined length formed on the surface of the pad, and the other mounting piece is formed on a portion corresponding to the groove portion on the back surface of the cover. In a vehicle seat cover mounting structure in which a surface fastener is provided and both the surface fasteners are joined to each other to attach the cover to the surface of the pad, the other surface fastener sews in a state of covering the tip of the cover mounting piece. In the longitudinal direction end portion of the other surface fastener, a notch portion is formed at a position closer to the tip side than the sewing portion and along the longitudinal direction from the longitudinal direction end portion side. .
[0011]
According to the second aspect of the present invention, since the cut portion is provided at the longitudinal end portion of the other surface fastener, even if a peeling load is applied to the cover, the peeling is performed as in the case of the previous item. The load is not applied to the longitudinal end portion of the surface fastener, but acts at a position shifted inward by the length of the cut portion. Accordingly, the joining strength of the surface fastener is improved, and the mounting strength of the cover is increased.
[0012]
According to a third aspect of the invention, a cover mounting structure of a vehicle seat according to claim 1 or claim 2, the mounting piece of the cover, overlapping the ends of a plurality of skin material constituting the cover It is characterized by being combined.
[0013]
According to the third aspect of the present invention, since the cover mounting piece is obtained by superimposing the ends of the plurality of skin materials, lines of a predetermined pattern appear on the surface of the cover, and the design of the cover is improved. .
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
[0015]
1 to 3 are views showing a first embodiment of the present invention. Reference numeral 1 denotes an automobile seat, which includes a seat cushion 2 and a seat back 3. The seat cushion 2 and the seat back 3 are each covered with a cover 4, but in this embodiment, the seat cushion 2 will be described as a representative.
[0016]
The seat cushion 2 has a structure in which a urethane foam pad 5 is attached to a cushion frame (not shown) and the pad 5 is covered with a cover 4. The surface of the cover 4 is attached to the pad 5 so that the position does not shift when an occupant sits down.
[0017]
That is, on the surface of the pad 5, there are two groove portions 6 extending in the front-rear direction and two other groove portions 7 that connect the groove portions 6 in the vehicle width direction, and an attachment piece 8 is provided on the back surface of the cover 4. Is formed. A male fastener 9 as “one surface fastener” is attached to the bottom surface of each of the grooves 6 and 7 with an adhesive 10.
[0018]
The attachment piece 8 of the cover 4 is formed by overlapping the end portions of the five skin materials 11 constituting the surface of the cover 4, and is formed corresponding to the grooves 6 and 7 of the pad 5. Yes. A female fastener 12 as “the other surface fastener” is sewn along the longitudinal direction together with the mounting piece 8 so as to wrap the tip. Since this cover 4 is formed by overlaying and sewing the end portions of the five skin materials 11, lines of patterns corresponding to the groove portions 6 and 7 appear on the surface of the cover 4 and are excellent in terms of design. ing.
[0019]
The sewing portion 13 for attaching the female fastener 12 to the attachment piece 8 is continuously formed at a predetermined pitch P. However, two sewing portions 13 are provided only at the longitudinal end portion of the female fastener 12. Omitted, an unsewn portion 14 having a length L corresponding to two pitches P is left as “peeling load displacement means”.
[0020]
Then, the front end of the female fastener 12 is joined to the male fastener 9 on the bottom surface of the groove portions 6 and 7, so that the surface of the cover 4 is attached to the pad 5. Is prevented.
[0021]
For example, as shown in FIG. 3, when a peeling load F is applied to the front end of the mounting piece 8 corresponding to the groove 6 along the front-rear direction in the direction (upward) in which the joint between the male fastener 9 and the female fastener 12 is peeled off. Originally, the peeling load F acts on the front end (longitudinal end portion) 12a2 of the female fastener 12 as it is through the sewing portion 13. In this embodiment, the front end 12a of the female fastener 12 is not yet applied. Since the sewing portion 14 is formed, the peeling load f at the female fastener 12 due to the peeling load F is shifted to the rear side by an amount corresponding to the length L of the unsewn portion 14 from the front end 12a.
[0022]
Therefore, unlike the prior art, the female fastener 12 does not move away from the front end 12a one after another, the joint strength of the female fastener 12 to the male fastener 9 is improved, and the attachment strength of the cover 4 is increased. Therefore, it is possible to improve the problem regarding the mounting strength while taking advantage of the feature of the surface fastener such as easy disassembly and recyclability.
[0023]
4 and 5 are views showing a second embodiment of the present invention. In this embodiment, a sewing portion 13 for attaching the female fastener 15 to the attachment piece 8 is provided continuously along the longitudinal direction of the female fastener 15, and a predetermined length L is provided on the distal end side of the sewing portion 13. The cut portion 16 is formed as “peeling load displacement means”. The cut portion 16 is formed in parallel with the sewing portion 13 from the front end (long end portion) 15 a side of the female fastener 15.
[0024]
Therefore, even in this embodiment, even if the peeling load F is applied to the front end of the mounting piece 8, the peeling load f at the female fastener 15 due to the peeling load F is from the front end 15 a of the female fastener 15 to the notch 16. It shifts to the rear side by an amount corresponding to the length L. Accordingly, as in the previous embodiment, the joining strength of the female fastener 15 to the male fastener 9 is improved, and the attachment strength of the cover 4 is increased.
[0025]
In the above description, the seat cushion 2 is taken as an example, but the present invention is also applicable to the seat back 3. In addition, the male fastener 9 has been described as being attached to the bottom of the groove portions 6 and 7 of the pad 5 with the adhesive material 10, but the present invention is not limited to this, and the member embedded in the pad 5 can be integrated when the pad 5 is foamed. It may be made.
[0027]
【The invention's effect】
According to the invention described in claim 1, the longitudinal end portion of the other surface fastener, since the sewn portions are provided, even if joined by peeling load in the cover, the peeling load of the fastener longitudinal direction It acts on the position shifted inward by the length of the non-sewn part, not added to the end. Accordingly, the joining strength of the surface fastener is improved, and the mounting strength of the cover is increased.
[0028]
According to the invention described in claim 2, since the cut portion is provided in the longitudinal direction end of the other surface fastener, even if a peeling load is applied to the cover, the peeling occurs. The load is not applied to the longitudinal end portion of the surface fastener, but acts at a position shifted inward by the length of the cut portion. Accordingly, the joining strength of the surface fastener is improved, and the mounting strength of the cover is increased.
[0029]
According to the third aspect of the present invention, since the cover mounting piece is obtained by superimposing the ends of the plurality of skin materials, lines of a predetermined pattern appear on the surface of the cover, and the design of the cover is improved. .
