Abstract
Official abstract text for this publication.
Provided is a method for manufacture of a seat for a vehicle, comprising a step of setting a return spring in a clamp jig, a step of clamping and fixing the return spring in the clamp jig, a step of inserting the return spring which is clamped in the clamp jig in an attachment unit, and a step of removing the return spring from the clamp jig.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for manufacture of a vehicle seat, comprising: a clamp jig; and a force application device for applying force to the clamp jig, wherein: the clamp jig includes a first holding member, a second holding member, and an operation member for opening and closing the first and the second holding members; the force application device applies force to the operation member so that the first and the second holding members are closed to clamp a return spring; the force application device applies no force to the operation member so that the first and the second holding members are opened to disengage the return spring from the first and the second holding members; the force application device is an air clamp; each top end of the first and the second holding members includes a recess for fixing the return spring; and in a state that the return spring is clamped and fixed with the first and the second holding members, a columnar space is defined by the first and the second holding members. 2. The device for manufacture of a vehicle seat according to claim 1 , wherein the return spring is of spiral type, having an outer end bent so as to be hooked on a hook piece attached to a seat cushion frame, and having the outer end disposed at an outer side of the first and the second holding members. 3. The device for manufacture of a vehicle seat according to claim 1 , wherein each of the first and the second holding members is made of a carbon steel material for mechanical structure. 4. The device for manufacture of a vehicle seat according to claim 3 , wherein the carbon steel material for mechanical structure is S45C.
