Problems solved by technology

[0002] At present, there are three types of lumbar cushions: one is the filling type, the cushion cover is made of flexible fabric, and the inside is filled with down, crushed sponge, cotton, PP cotton, etc. Its advantages are various shapes, low cost, and is suitable for production. The disadvantage is the filling. The material is soft and loosely combined with each other. The support provided by the cushion is not enough, which not only cannot relieve fatigue, but even makes the lumbar spine more unreasonable and damages the health. Its advantage is that after the elastic material is compressed, the support surface can fully contact with the waist of the human body, providing greater support force. The disadvantage is that the human body compresses th

Embodiment Construction

[0007] figure 1 It is a perspective view of a specific embodiment of the cushion with adjustable support surface in the present invention. The support surface is composed of several end caps 9 positioned at the top of the support rod 1, and the support surface is in its initial shape before use. When the locking device does not lock the support rod 1, the user's waist can push the end cover 9, so that the height of the support rod 1 protruding from the bottom surface of the guard plate 2 adapts to the waist curve of the corresponding part, and the end cover 9 forms a new After the locking device locks the support rod 1, the shape of the new support surface is fixed. Both sides of guard plate 2 are curved surface shapes, are used for supporting user's waist side, prevent waist from sliding left and right on the back cushion. The back cover 3 leans against the seat back, supporting the power applied by the human body backward on the back cushion.

The invention relates to a back cushion with capacity of adjusting the shape of a waist support surface randomly. A targeted support curved surface can be obtained by adjusting the shape of the support surface of the back cushion in reference to the standard sitting posture of a user; the shape of the support surface is fitted with the waist curve of each user, and uniform and powerful support can be provided for the waist, so that the functions of keeping the sitting posture and relieving fatigue are realized.

Description

technical field [0001] The invention relates to a back cushion whose shape of a lumbar support surface can be adjusted arbitrarily. By adjusting the support surface of the back cushion, the back cushion is closely fitted to the waist of the user, and the force on the waist is more uniform, so as to maintain the sitting posture and relieve fatigue. Background technique [0002] At present, there are three types of lumbar cushions: one is the filling type, the cushion cover is made of flexible fabric, and the inside is filled with down, crushed sponge, cotton, PP cotton, etc. Its advantages are various shapes, low cost, and is suitable for production. The disadvantage is the filling. The material is soft and loosely combined with each other. The support provided by the cushion is not enough, which not only cannot relieve fatigue, but even makes the lumbar spine more unreasonable and damages the health. Its advantage is that after the elastic material is compressed, the suppor...
