Summary of the invention:

The purpose of this utility model provides a kind of collapsible waist support chair that can use in family and office space.The principle that it utilizes gravity to disperse can alleviate above the waist gravity to the pressure at right angle of backbone, can alleviate the slight illness that the upper body deadweight produces the compressing of waist disk effectively.

Its structure is: the height adjustable movable hand rail that the both sides of seat respectively have an energy that armpit is held, and allowing above the waist, the part of body weight is dispersed on the seat by handrail; Simultaneously, rib and the position height between the hipbone in the inboard of pair of armrests are equipped with soft elasticity protruded object, rib is linked closely, fixing waist, can more a part of weight be distributed on the handrail on both sides again, vertically be pressed in epispinal weight thereby alleviate widely, alleviate compressing effectively the waist disk.

Seat board of the present invention constitutes by three layers respectively:

A, upper plate have two of sizes, and slideway respectively is equipped with at the two ends of plate, and two upper plates are fixed itself and following intermediate active plate with screw respectively; B, the intermediate active plate is combined into by two serration plates, laterally can stretch, and extension spring is equipped with in the junction, edge of two portable plates, can stretch; C, base plate, with screw with two blocks of intermediate active plates wherein one be fixed on the base plate, another piece intermediate active plate just can cross directional stretch, retraction.

Handrail: the slide block of handrail bottom embeds slideway, can be to front or rear moving hand-rail, and bow or sit straight before the adjustment sitting posture; Be connected with hinge between slide block and the handrail, can fold; Soft elasticity male material is equipped with at the handrail middle part, links closely to the inside between rib and the hipbone, to separate distance therebetween as far as possible, alleviates by the compressing of own wt to the waist disk, and the part of the above weight of rib is distributed on the handrail; Elevating lever is equipped with on the top of handrail, and adjustable height allows weight drop on the handrail up near armpit as far as possible; The part that handrail is close to armpit adopts soft aerated materials, to prevent by the issuable disease of hand of oxter blood vessel pressurized.

Movable back cushion: adopt flexible material that low back is fixed, two ends are bonded at the handrail back with magic strap.

Advantage of the present invention is: seat laterally can stretch; Handrail is vertically removable, can adjust up and down; The time spent is not collapsible; In light weight, easy to carry.The crowd of being suitable for is extensive.Be staff such as IT industry employee, office, school, driver, and frequent out of town trip is seized the opportunity the rehabilitation care appliance that personnel are alleviated pain in the back for a long time by bus.

The specific embodiment:

The utility model can use separately also can be placed on other chairs uses.

Embodiment 1:

Armrest seat 2 is connected on the base plate, and elevating lever 9 is equipped with on the top of armrest seat 2, is connected with the back cushion 3 of elastomeric material above the elevating lever 9 between 1, two armrest seat 2 of fixed armrest.Back cushion 3 two ends can be bonded at the armrest seat back with magic strap.Elevating lever 9 can be adjusted the height of handrail 1 according to people's height, adjusts the back and fixes with resilient key, the headrest of similar automobile chair fixing.Armrest seat 2 is connected on the slide block 8 in the slideway that is fixed on the base plate 4 by folding 7, and the time spent can inwardly not fold.Armrest seat 2 can move forward and backward by the slide block 8 in the slideway 4, bows or sits straight before the adjustment sitting posture.
