Abstract
The utility model relates to a device which can adjust the convex surface of a backrest of a chair (or sofa). The utility model can be used for renewing and reforming the existing chairs. The device is mainly composed of a bracket, a rack bar, a moving mechanism arranged on the rack bar and a convex surface mechanism, wherein, the rack bar can be moved up and down in the bracket, the moving mechanism is arranged on the lower part of the bracket, and a handwheel is rotated to enable a gear to drive the rack bar to control the convex surface mechanism to move up and down in a slide way of the bracket. The convex surface mechanism which is arranged on the upper part of the rack bar can be moved up and down in the slide way of the bracket. The handwheel can adjust the height of the convex surface by rotating the convex surface mechanism. The handwheel is used for adjusting the position and the height of the convex surface in the waist, so the waist of a sitting person can be supported, and the sitting person can feel very comfortable.
Description
The utility model relate to a kind of can adjust seat (or sofa, below slightly) backrest protruding and device.Can renovate to existing seat with this.
As the saying goes: do not back up, the waist bar is just not hard.Often people, the especially driver of seating chair feel back deeply by real, and waist just poises; If waist leans on real, the hunchback of must bending over.In the course of time, make awkward before and after the people, not only tiredly also easily cause spinal curvature, so lumbar strain.Though someone buys the back pads plug behind waist, an activity also is the part trouble.
For overcoming the above-mentioned defective of prior art, the utility model aims to provide a kind of device that can adjust the seat back convex surface, can change position and the height of backrest at the waist convex surface with this.
For achieving the above object, the utility model mainly is made of support, tooth bar and the travel mechanism that is installed on it and convex surface mechanism.Tooth bar is installed in the support and can moves up and down.Gear shaft in the travel mechanism is installed in the bottom of support, and the one end is equipped with ratchet and handwheel, and gear is equipped with at two.Mechanism moves up and down in the slideway of support thereby rotation hand wheel can make gear driven tooth bar control convex surface.After the convex surface position is determined, the ratchet on the gear shaft is realized self-locking at the ratchet on the support.Convex surface mechanism is installed in the top of tooth bar and can moves up and down in slideway, and screw mandrel is the left and right button of symmetry, and the one end is equipped with handwheel.Slide block is housed respectively on the correspondence position of screw mandrel, and a side of slide block is joined by bearing pin and connecting rod respectively, and connecting rod joins by bearing pin and cross-arm again.For making slide block stable, it is gone here and there respectively up and down guide rod.Rotation hand wheel can make the slide block on the screw mandrel do motion relatively or contrarily and drive the distance of cross-arm apart from screw mandrel, thereby plays the adjustment of convex surface height.
Owing to take above-mentioned technical solution, advantage of the present utility model: the one, can adjust the position of seat back waist convex surface, use to adapt to different height people; The 2nd, the convex surface height is adjustable, to adapt to the human needs of different stature different condition; The 3rd, this device is supporting in can leaning against at the seat of new system, also can lean against existing seat and renovate.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A view among Fig. 1.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is once described again.Referring to Fig. 1, Fig. 2 as can be known, the utility model mainly is made of support 1, tooth bar 6 and the travel mechanism that is installed on it and convex surface mechanism.Tooth bar 6 is installed in the support 1 and can moves up and down.Gear shaft 5 in the travel mechanism is installed in the bottom of support 1, and the gear 7 with tooth bar 6 interlocks is equipped with at two, and the one end is equipped with ratchet 3 and handwheel 4.Thereby rotation hand wheel 4 can make gear 7 drive tooth bar 6 control convex surface mechanisms and move up and down in the slideway of support 1.After the convex surface position was determined, the ratchet 3 on 2 pairs of gear shafts 5 of the ratchet on the support 1 was realized self-locking.Convex surface mechanism is installed in the top of tooth bar 6, and can move up and down in the slideway of support 1.Screw mandrel 9 is the left and right button of symmetry, and the one end is equipped with handwheel 8.Slide block 10 is housed respectively on the correspondence position of screw mandrel 9, and for making slide block 10 stable, going here and there respectively on it has guide rod 11.Referring to Fig. 2 as can be known, a side of slide block 10 is joined by bearing pin 14 and connecting rod 12 respectively, and connecting rod 12 joins by bearing pin 14 and cross-arm 13 again.It is far away or near apart from screw mandrel 9 that rotation hand wheel 8 can make the slide block 10 on the screw mandrel 9 make the cross-arm 13 of operation drive relatively or contrarily, thereby play the high or low adjustment of convex surface.The utility model can not damage the style and features of former seat when installing, by bolt support 1 is fixed on the frame that leans against to get final product.
The inventor has installed the utility model on a taxi seat, the driver feels as snug as a bug in a rug, and obtained colleague's consistent the praise.
