VEHICLE SEAT

摘要

Disclosed is a vehicle seat that is capable of changing a property of S springs with a simple configuration and therefore improves a seating property by changing the property of the S spring in response to a physique of a passenger.;In regard to a vehicle seat 1 in which S springs 6 are stretched in a seat cushion frame that supports a seat cushion on which the passenger sits, a restriction member 13 that is detachably attached to each of the S springs 6 and partially restricts an extensional deformation of the S springs 6 is provided. The restriction member 13 includes a pair of wire hook portions 15 and 16 that is hooked on a horizontal portion 8 and a back-end horizontal portion 12 of the S spring 6, and a long wire portion 14 that connects the pair of wire hook portions 15 and 16. When the pair of wire hook portions 15 and 16 of the restriction member 13 is hooked, extensional rigidity of the S spring 6 may be raised and therefore bending rigidity of the S spring 6 may be changed by changing the hooking position of the pair of wire hook portions 15 and 16 of the restriction member 13.

1. A vehicle seat in which S springs are stretched in a seating portion in a front-back direction of a vehicle, the vehicle seat comprising:
restriction member, which is detachably attached to the S springs, for partially restricting an extensional deformation of the S springs wherein each of the S springs includes, a vertical portion that extends in a stretching direction of the S spring, and a horizontal portion that extends in a direction orthogonal to the stretching direction of the S spring, wherein the restriction member includes, a long member, and two or more locking portions that are attached to the long member and are locked on the horizontal portion, and wherein when the locking portion is locked on the horizontal portion, the extensional deformation of a back-end portion of the S spring in a front-back direction of the vehicle is partially restricted by the restriction member.
