Description

The present invention relates to a seat lock portion structure, and more particularly to a lock portion structure in a seat cushion that is flipped up with a front portion as a rotation center.

  The seat cushion of the flip-up seat is locked when the tether wire provided on the rear end face is engaged with the latch on the vehicle body side in the state of use, and the seat cushion is provided on the front side by releasing the lock. Is configured to jump up to the center of rotation.

  As shown in FIG. 3, this type of conventional lock portion is formed in a notch recess 30 formed by notching a foam pad 3 with a tether wire 5 welded to the frame 7 on the rear end surface S side of the seat cushion SC. The cutout recess 30 and the tether wire 5 are covered with a covering piece 8 made of the same material as the skin material of the seat cushion S, and the covering piece 8 forms a skin material that forms the rear end surface S of the seat cushion SC; It is sewed to a skin material 2 on the upper surface of the seat cushion SC and a bottom cloth 4 such as a carpet attached to the bottom surface of the seat cushion SC.

  The covering piece 8 is provided with a slit 80 from which the tether wire 5 protrudes to the outside. When the seat cushion SC is locked, the tether wire 5 is protruded from the slit 80 and engaged with a hook or the like provided on the vehicle body. It is comprised so that it may engage with a member.

  When the lock is released and the seat cushion SC is lifted up, the tether wire 5 is covered with the covering piece 8 as shown in FIG.

  Therefore, since the tether wire 5 is concealed by the covering piece 8 as described above in the conventional product shown in FIG. 3, the position of the tether wire 5 cannot be seen from the outside when locked, and the position is difficult to understand. Therefore, the tether wire 5 has to be protruded to the outside and engaged with the hook, which is difficult to engage with the hook.

  Such a problem can be solved by forming the synthetic resin cover member in advance so that the tether wire 5 is exposed to the outside instead of the covering piece 8, but the synthetic resin cover member is disposed on the seat cushion SC side. In order to fix the cover member so that it does not fall off, it is necessary to provide a fixing member inside the seat cushion, and to fasten the cover member to the fixing member.

  Therefore, the present invention is to make it easy to easily and easily attach the cover member covering the notch recess having the tether wire to the sheet, so that the tether wire can easily engage with an engaging member such as a hook.

  In order to achieve the above object, the seat lock structure according to the present invention includes a locking member disposed in a notch recess of the sheet and engaged with an engagement member provided at the rear of the sheet, and the notch recess A cover member mounted inside and having the locking member disposed therein, wherein the cover member is formed of a molded nonwoven fabric formed by impregnating a nonwoven fabric with a synthetic resin material and molded into a concavo-convex shape. It is the structure formed by sewing integrally with the outer cover member of the sheet.

  The seat locking structure described above is suitable for a seat that is attached to the vehicle body so that the seat can be flipped up about the rotation center, and a notch recess for the seat is provided on the rear end surface of the seat cushion.

  Further, the above locking member is a striker such as a tether wire, and is disposed in a notch recess provided on the rear end surface of the seat cushion, and engages with an engaging member such as a latch provided on the vehicle body located behind the seat cushion. By doing so, the seat cushion is locked.

  According to the present invention, since the cover member is formed of a molded nonwoven fabric and sewn integrally to the skin material of the sheet, the cover member is fixed to the sheet, and the cover member can be easily and easily attached to the sheet. The assembling property of the members can be improved.

  Further, since the cover member has a certain shape retaining property, the arrangement state of the locking member in the cover member is good, and since the locking member can be seen from the outside, it can be reliably engaged with the engaging member, and the seat Lockability can be improved.

  An embodiment of the present invention will be described below with reference to FIGS.

  In the figure, the same reference numerals as those in FIG.

  In the figure, reference numeral 1 denotes a cover member, and this cover member 1 is formed from a molded nonwoven fabric. The molded nonwoven fabric is impregnated so that the nonwoven fabric is impregnated with a synthetic resin material and matches the shape of the notch recess 30. It can be sewn, such as a press, or the like, and can be sewn, such as the skin material 2 constituting the surface of the seat cushion SC. is doing.

  The cover member 1 is provided with a slit 1A through which the tether wire 5 is inserted, and the tether wire 5 is disposed so as to be exposed to the outside from the slit 1A.

  Further, the terminals 10 and 20 of the cover member 1 are sewn integrally to the outer cover member 20 that forms the rear end surface S of the seat cushion SC and the outer cover member such as the carpet 4 provided at the bottom of the seat cushion SC. It is worn.

  The seat cushion SC is locked to the vehicle body A by engaging the tether wire 5 with an engagement member such as a hook 6 provided on the vehicle body A behind the seat cushion SC.

  Although the illustrated hook 6 is provided on the vehicle body A, it may be provided on the seat back SB side. In such a case, the seat back SB is locked on the vehicle body side.

  The seat cushion SC shown in FIGS. 1 and 2 has a structure in which, after the seat back SB is moved forward on the seat cushion SC, the seat cushion SC jumps forward around the hinge provided at the front thereof.

  In the state in which the seat cushion SC is flipped up and in the locked state shown in FIG. 2, the tether wire 5 is always exposed from the cover member 1 and disposed so as not to protrude outward from the rear end surface S of the seat cushion SC. Has been.

  Therefore, since the position of the tether wire 5 is visually recognized from the outside, the tether wire 5 can be easily hooked on the hook 6 and the like, and the locking property of the seat cushion can be improved.

  Further, since the tether wire 5 does not protrude outward from the seat cushion SC, the tether wire 5 does not become a projection when the seat cushion SC is flipped up.

  Furthermore, since the cover member 1 is formed of a molded nonwoven fabric, no abnormal noise is generated even when the cover member 1 comes into contact with the hook 6 or the like, and there is no possibility of breakage.

  In addition, since the cover member 1 can be fixed by sewing to a cover member such as the skin material 2 constituting the seat, the attachment property to the seat is improved.
