Abstract
The invention discloses a component suitable for various vehicle seat backrests, in particular to a waist supporting device of a seat backrest, which can regulate waist fatigue states of different users in process of using the waist supporting device so as to ensure users working for long time to be comfortable. The waist supporting device is provided with a fitting seat on which a waist supporting part is arranged; a waist supporting drive set driving the waist supporting part to move up and down is arranged between the fitting seat and the waist supporting part; the waist supporting drive set comprises a worm connected with the fitting seat and a worm wheel meshed with the worm; and the worm wheel is connected with the waist supporting part. The waist supporting device of the seat backrest has firm structure and convenient and stable operation, can be regulated from both sides to control the waist supporting height and is accurately and steplessly regulated to the most comfortable waist supporting height, and the displacement parameters of regulation range is higher.
Description
Technical field
The present invention relates to a kind of parts that are applicable to various vehicle seat backs, especially a kind ofly can satisfy different user, make the user of long working obtain comfortable a kind of backrest and endure the waist device in use to the adjustment of lumbar fatigue state.
Background technology
In the prior art, generally this series products all adopts the line seat shoulder backrest of stopping to endure the waist structure, backrest release poor rigidity, and the operating flexibility instability lacks the comfort level of whole seat.
Summary of the invention
The technical problem to be solved in the present invention is: shortcoming and deficiency in order to solve above-mentioned existence provide a kind of backrest to endure the waist device.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of backrest is endured the waist device, has mount pad, mount pad is provided with very waist member, mount pad and very being provided with between the waist member drives the drive unit that waist member very moves up and down, drive unit comprise the worm screw that is connected with mount pad and with the worm gear of worm engaging, worm gear is connected with waist member very, utilize pivoted lever be mixed in up and down cover plate and very the waist member utilize flat head rivet to be riveted together, worm and gear is carried out Design Orientation, keep the uniqueness and the reliability of worm and gear movement locus.
Further, use for the ease of convenient, be connected with control stick and the handwheel of moulding that is connected with control stick on the worm screw, utilize limited block to play limiting displacement at the two ends of worm screw and guarantee that worm screw rotates effect flexibly, utilize firm the loading onto of jump ring to mould handwheel at the two-end-point of action bars.
For the waist height is endured in adjusting accurately, very the waist sheet element comprises horizontal very waist sheet and utilizes erecting of rivet to endure the waist sheet with horizontal very waist sheet.
Design has eccentric orfice on the worm gear, very the waist member is endured on the waist drive unit for being assemblied in, and have one very the waist sheet be fixedly connected on the eccentric orfice of worm gear, it is under the transmission of turbine, pulling very waist sheet makes very waist member realization stretch Qu Yundong, regulate thereby obtain certain arch form height, on the present backrest software of final body (sponge), allow the human body waist obtain comfortable height and support.
The invention has the beneficial effects as follows: backrest of the present invention is endured the waist device, and sound construction, easy to operate stable can be regulated at bilateral and control the very height of waist, and step-less adjustment is to the very waist height of the most comfortable accurately, and the displacement parameter of adjustable range is than higher.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Among the figure 1, mount pad, 11, pivoted lever, 2, waist member very, 21, horizontal very waist sheet, 22, perpendicular very waist sheet, 23, cover plate, 3, drive unit, 31, worm gear, 32, worm screw, 33, limited block, 34, action bars, 35, mould handwheel, 36, jump ring.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of backrest is as shown in Figure 1 endured the waist device, comprise mount pad 1, design according to installation requirements, guarantee to rationalize and install, mount pad 1 is provided with very waist member 2, mount pad 1 and very being provided with between the waist member 2 drives the drive unit 3 that waist member 2 very moves up and down, drive unit 3 comprises worm screw 32 that is connected with mount pad 1 and the worm gear 31 that meshes with worm screw 32, one end of worm gear 31 is connected with perpendicular very waist sheet 22, utilizes pivoted lever 11 to be mixed in up and down cover plate 23 and to endure waist member 2 and utilize rivet to be in the same place.
Very waist sheet element 2 comprises horizontal very waist sheet 21 and utilizes erecting of rivet to endure waist sheet 22 with horizontal very waist sheet 21.
A kind of course of work of backrest device: utilize mount pad 1 to be engaged on the backrest structure, firmly regulate and mould handwheel 35, control stick is rotated, drive worm screw 32 motions of running part, realize that again worm gear 31 rotatablely moves, design has eccentric orfice on the worm gear 31, utilize the motion that is meshing with each other of worm screw 32 and worm gear 31 to control very waist member 2 displacements simultaneously, one endures the waist sheet is fixedly connected on the eccentric orfice of worm gear 31, it is under the transmission of worm gear 31, pulling very waist sheet makes very waist member 2 realizations stretch Qu Yundong, thereby obtaining certain arch form height regulates, on the present backrest software of final body (sponge), allow the human body waist obtain comfortable height and support, thereby realize that very waist member 2 is in the motion difference in height of surveying high point.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
