Abstract

A vehicle seat (1) is provided with an upper frame (20) on which a seat section (10) is mounted, a lower frame (22) which is mounted on a floor (3) and faces the upper frame (20); a link mechanism (24) which connects the upper frame (20) and the lower frame (22) and which adjusts the position of the upper frame (20) relative to the lower frame (22), a belt member (30) which has one longitudinal end connected to the rear side of the upper frame (20) and which has a deformation section (32) which slackens, and a pulling mechanism (50) which, in a vehicle collision, pulls the other longitudinal end of the belt member (30) to stretch the slackened deformation section (32).

Description

technical field [0001] The present disclosure relates to a vehicle seat. Background technique [0002] Vehicles such as trucks are equipped with vehicle seats having a cushioning function. This vehicle seat has a link member for adjusting the position of the upper frame between the upper frame on which the seat portion is placed and the lower frame attached to the floor surface. [0003] However, when the vehicle collides, the seat portion may fall forward. In response to this, a method has been proposed in which a belt member is connected to an upper frame on which a seat portion is mounted so that upward movement of the upper frame is restricted. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2004-353770 Contents of the invention [0007] The technical problem to be solved by the invention [0008] However, even if the belt member is used to limit the upward movement of the upper frame as described ...
