Detailed Description

As shown in fig. 1 to 7, an automobile seat backrest with spring shock absorption comprises a backrest framework 6 and a waist-supporting back plate 4, wherein the front side surface of the waist-supporting back plate 4 is connected with a plurality of waist-supporting elastic pieces 5; when the passenger need adjust the top waist position, when the middle bending bulge of top waist backplate reached suitable position, reach top waist effect, each top waist elastic component 5 was also compressed along with the bending bulge of top waist backplate this moment, it is the biggest at the protruding position compression capacity of top waist backplate, steadilyd decrease toward the next door in proper order, when the passenger leaned on the back of the chair, top waist elastic component 5 further compressed, had the cushioning effect when satisfying top waist effect, and then improved back of the body comfort level, reduced the tired sense of the back of the body.

In this embodiment, the number of the top waist elastic members 5 is 10, and the top waist elastic members 5 are vertically arranged in two left and right rows.

In this embodiment, the waist-supporting elastic member 5 includes a rear sleeve 501 fixedly connected to the waist-supporting back plate and a front sleeve 502 sleeved on the rear sleeve 501 and capable of sliding relative thereto, and the front sleeve and the rear sleeve are provided with a waist-supporting spring 503 pushing the front sleeve forward; the motion freedom degree of the top waist spring is limited by the front sleeve and the rear sleeve which are sleeved with each other outside the top waist spring, the problems of spring dislocation and the like caused by uneven stress of the backrest are prevented, and the structural stability is ensured.

In this embodiment, a fixing block 505 is disposed inside the front end of the front sleeve 502, a through hole is formed in the fixing block, and the front end of the steel wire of the waist-supporting spring 503 is hooked on the through hole of the fixing block, so as to ensure that the movement direction of the spring is unique; the front end of the front sleeve 502 is provided with a disc-shaped stress part 504, so that the stress area is increased, and the twisting of the waist spring and the discomfort possibly generated when a passenger backs are avoided.

In this embodiment, the rear sleeve 501 is fixedly connected to the lumbar support plate 4 by a bolt passing through the lumbar support plate from the rear to the front, and a nut 506 screwed with the bolt is fitted to the rear end of the rear sleeve 501.

In this embodiment, top waist backplate 4 passes through wire 7 to be installed on back skeleton 6, and manual regulator 2 is installed to back skeleton 6 lateral part, has handle 1 on the manual regulator, and the waist position back of top waist backplate 4 is articulated mutually with the lower extreme of a pull rod 8, the upper end of pull rod is rotated and is installed

pulley

9, 3 work ends of cable of manual regulator 2 pass under the top waist backplate upper end and bypass the pulley after-fixing in plastics backplate upper end in order to realize that manual regulator passes through cable control pulley rebound. Through handle 1 on the clockwise rotation manual regulation ware 2, taut cable 3, on pull rod 5 is used through pulley 9 with effort to cable 3, upwards pulling behind the 5 atress of pull rod pushes up waist backplate 4, makes 4 atress deformations of top waist backplate produce hunch-up, plays and supports driver's waist effect, handle on the anticlockwise rotation manual regulation ware, loosens the cable, pushes up waist backplate 4 and relies on self elasticity reconversion, relieves the lumbar support effect.
