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 of a seat frame for a vehicle comprising:

a connecting rod that connects, in a width direction of the seat frame, a pair of side frames of the seat frame that extend in parallel;

a spring member that is configured to support a pad body, the spring member includes engaging portions that are engaged with the connecting rod; and

cover members that cover joints between the side frames and the connecting rod, the cover members each include an extension portion that extend toward a center of the seat frame to a position that is at least one of in contact with and adjacent to the connecting rod, wherein

each extension portion includes an end that faces the center of the seat frame and that abuts on a respective engaging portion of the spring member.

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 at least one of in contact with and adjacent 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 the width direction of the seat frame that defines a parameter of an area of a seating surface of a seat occupant,

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

the cover members are respectively provided on the joints of the side frames and the connecting rod at both sides of the seat frame 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 and are configured to avoid contact with the pad body that is configured to be placed above the connecting rod.

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

the engaging portions are clipping portions that have an arcuate shape that corresponds to an outer peripheral surface of the connecting rod, and

the clipping portions are clipped to the outer peripheral surface of the connecting rod.
