Claims

[Scope of utility model registration request]

Several zigzag springs 6 are arranged in parallel in the front-rear direction at predetermined intervals in the left-right direction in a substantially rectangular skeleton frame 2 provided in the seat 1, and a steel wire is attached to the rear of the group of 6 springs. A frame line 7 consisting of a front frame 8, a rear frame 9, a left frame 10, and a right frame 11 formed by bending
The frame line 7 is connected to the left frame 10 or the right frame 11 by a connecting tube 28 at an intermediate position, and the zigzag spring 6 and the frame line 7
In the spring structure consisting of
Reference numeral 8 is formed by winding a metal plate, and the middle part of the connecting cylinder 28 forms a concave part 29 which is recessed in a square shape. This is a spring structure for a vehicle seat, etc., in which the zigzag spring 6 and the connecting tube 28 are located at the top so that they do not come into direct contact with each other.
