Description

  The present invention relates to an automobile seat that is provided with a seat cushion that can be folded up by folding up a seat cushion.

  As shown in FIG. 3, as the seat for an automobile, the seat cushion 1 is flipped up with the rear side facing upward, and the headrest 2 is tilted forward so that the seat back 3 is placed on the under cover 4 of the seat cushion 1. Foldable seats are provided.

  In the vehicle seat, the connecting rod 5 is spanned between the seat cushion 1 and the under frame 6 so that the seat cushion 1 can be raised. When the seat cushion 1 is flipped up, as shown in FIG. 4, the seat cushion 1 is lifted upward from the front side and pulled out in the horizontal direction. The seat back 1 needs to be in a vertical posture.

  In the automobile seat, it is desirable to take measures to prevent the seat cushion from jumping up, assuming that it receives inertia due to an unexpected external force acting in the forward direction of the vehicle body. As a measure for preventing the seat cushion from jumping up, an inertia lock may be provided. However, the inertia lock is mechanically complicated and expensive, so that the entire seat becomes expensive.

  The problem to be solved by the present invention is to take measures for preventing the seat cushion from jumping up mechanically and inexpensively.

The present invention provides an automotive seat including a seat cushion that pivotally supports the front side to the left and right of the underframe and can flip the rear side forward.
Extending forward from the rear frame of the under frame and facing the lower surface of the lower part of the seat back and the upper surface of the rear part of the seat cushion. It is provided.

  In the automobile seat according to the present invention, the seat cushion can be prevented from jumping up only by the member on the seat cushion side, regardless of the position of the seat back, and the seat cushion can be prevented from jumping up by a simple and inexpensive mechanism.

  The illustrated automobile seat is formed by bending a pipe member into a substantially U-shape as shown in FIG. 1, and a bearing is mounted in the bottom width direction of the cushion frame 8 by a bearing bracket 7 so that the central horizontal shaft portion 5a can be rotated. The left and right vertical axis portions 5b are pivotally attached to a bracket 9 rising from the front side of the under frame 6, and the connecting rod 5 is provided between the seat cushion 1 and the under frame 7 so as to be retractable. Can be lifted up from the under cover 4 by the connecting rod 5.

  In the automobile seat, a U-shaped lock fitting 10 is attached to the rear frame 11 of the under frame 6 for latching a child seat (not shown). The lock fitting 10 is bent in a U-shape so that the horizontal axis portion is used for latching the child seat and the base end side of the vertical axis portion is fixed to the rear frame 11 of the underframe 6 by welding.

  As shown in FIG. 2, the lock fitting 10 extends from the rear frame 11 of the underframe 6 to the front side of the horizontal shaft and faces between the lower portion of the seat back 3 and the rear portion of the seat cushion 1. Since the cushion 1 is attached to the rear frame 11 of the underframe 6 while being brought into contact with the rear upper surface of the cushion 1 and being forwardly tilted, it is provided as a member for preventing the seat cushion from jumping up.

  The seat cushion jumping-up type automobile seat configured in this way also serves as a child seat lock fitting 10 that is normally equipped. The child seat lock fitting 10 is prevented from jumping up by pressing the rear side of the seat cushion 1. Since it is attached to the rear frame 11 of the underframe 6 as a member, the seat cushion can be prevented from jumping up with a simple and inexpensive mechanism.

It is explanatory drawing which shows the seat cushion jumping-up type vehicle seat which concerns on this invention in the raising state of a seat cushion. It is explanatory drawing which mainly shows the locking bracket of the child seat with which the seat cushion jump-up-type vehicle seat of FIG. 1 is equipped. It is a side view which shows the seat cushion flip-up type vehicle seat which concerns on a general example in the folding state. It is explanatory drawing which shows the raising procedure of the seat cushion in the vehicle seat of FIG.
