Abstract

The present invention relates to a spring member mounting structure, which is a structure for mounting a spring member on a cushion frame connecting side frames by use of a rear pipe. The spring member has rear clipping portions engaged with the rear pipe. Cover members, which are provided at seat central sides of connecting portions of the side frames and the rear pipe, have extension portions extending toward the seat central sides. The rear clipping portions abut on ends of the seat central sides of the extension portions, and are mounted to the rear pipe by width direction positioning of the spring member.

Claims

1. A spring member mounting structure, which is a spring member mounting structure of a seat frame for a vehicle connecting a pair of side frames extending in parallel with both sides of a seat in width direction by use of a connecting rod, the spring member mounting structure comprising:

a spring member which places and supports a pad body as a cushion material;

the spring member has engaging portions engaged with the connecting rod, and

cover members provided at a central side of the seat frame for a vehicle of connecting portions of the side frames and the connecting rod;

the cover members have extension portions, and the extension portions, which extend toward the central side of the seat frame for a vehicle to a position where the extension portions are in contact with or close to the connecting rod, have ends of the central side of the seat frame for a vehicle abutting on the engaging portions.

2. The spring member mounting structure according to claim 1, wherein

the ends of the extension portions abut on the engaging portions so as to determine a width direction position of the spring member.

3. The spring member mounting structure according to claim 1, wherein

a portion of the extension portions, which comprises the ends, extends to be in contact with or close to an outer peripheral surface of the connecting rod.

4. The spring member mounting structure according to claim 1, wherein

the spring member has a length in a width direction of the seat for supporting substantially the entire area of a seating surface of a seat occupant,

the engaging portions are provided at both ends in a width direction of the spring member, and

the cover members are respectively provided on the connecting portions of the side frames and the connecting rod at both sides of the seat frame for a vehicle, so as to position the spring member from left and right sides.

5. The spring member mounting structure according to claim 1, wherein

the extension portions extend along an outer peripheral surface of the connecting rod with which the pad body placed above the connecting rod is not in contact.
