Problems solved by technology

[0007] However, when a large load is applied to the synthetic resin hook member 24, the locking portion of the hook member 24 that is locked with the seat frame 20 is deflected and deformed, and the hook member may be stretched due to the expansion of the locking portion. 24 from the situation of the seat frame 20
Once the hook member 24 is detached, the support formed by the planar elastic body 21 will no longer exist. Therefore, for the seat cushion, the problem of the buttocks sinking below occurs, and for the seat back, the problem of the back sinking behind occurs.

[0017] Such as figure 1 As shown, the automotive seat has inside it a seat cushion frame 1 constituting a skeleton of a seat cushion, and a back frame 2 constituting a skeleton of a seat back. The back frame 2 is supported so as to be able to tilt back and forth with respect to the cushion frame 1 via a reclining mechanism including a reclining shaft 3 . The details will be clarified by the description below, but in the first embodiment, the present invention is applied to a locking portion between the cushion frame 1 and the first hook member 7 to be described later. Therefore, in the first embodiment, the cushion frame 1 corresponds to the "seat frame" described in the present invention.

[0018] The cushion frame 1 includes a pair of left and right first frame members 1A, 1A, and a pair of front and rear second frame members 1B, 1B extending in the vehicle width direction to connect the frame members 1A, 1A to each other. In addition, the second frame member 1B correspon...

Abstract

Provided is a seat which comprises: a seat frame constituting a framework for a seat cushion or seat back; a synthetic resin hook member having a locking portion locked to a frame member as a part of the seat frame; a stretchable planar elastic body attached to the hook member locked to the frame member so as to be mounted to the seat frame in a tensioned state; and an anti-expansion mechanism for avoiding a situation where the hook member is expanded and thereby the hook member is disengaged from the frame member. In this way, even if a large load is applied onto the stretchable planar elastic body, the disengagement of the hook member from the seat frame is prevented.

Description

technical field [0001] The present invention relates to a seat including a seat frame and a planar elastic body stretched on the seat frame. Background technique [0002] Conventionally, for example, a seat of the type disclosed in Japanese Patent Laid-Open Publication No. 2002-306273 is known. This type of seat is Figure 5A As shown, there is a seat frame 20 and a stretchable planar elastic body 21 stretched on the seat frame 20 . [0003] One end of the elastic skin body 22 and the reinforcing cloth 23 is sewn to the end of the planar elastic body 21 . The other ends of the elastic skin body 22 and the reinforcing cloth 23 are locked to the cable body 25 of the seat frame 20 via a substantially J-shaped hook member 24 formed of a synthetic resin material, and the elastic skin body 22 and the reinforcing cloth 23 The middle part of is wound on the seat frame 20. Thus, the planar elastic body 21 is stretched on the seat frame 20 . [0004] In addition, there is a seat o...
