Description

Simple manual waist support structure

Technical Field

The utility model relates to a car seat structure especially relates to a simple and easy manual waist holds in palm structure.

Background

At present, the middle-high-grade automobile seat is provided with an adjustable waist support so as to improve the comfort of driving and riding. The waist support supporting system usually controls the supporting strips to be arched or unfolded and flat by driving components such as a screw rod, a flexible shaft and a pull wire through a driving unit, so that the front and back directions of the waist supporting plate can be adjusted. However, the structure has more parts, more complicated assembling procedures and higher machining precision requirement, and is easy to generate noise in actual operation, thereby bringing discomfort to passengers. In addition, with the rapid development of the automobile industry, demands for production efficiency, weight reduction of products, and the like are increasing dramatically.

At present, the internal framework of the automobile seat backrest is diversified, the simpler the structure is, the lower the cost can be, the weight is reduced, the market competitiveness is improved under the condition of meeting the supporting requirement from the aspect of simplicity, and particularly under the condition of some low and medium requirements, the manual structure which is often simple and low in price can meet the market requirement, so that the manual waist support adjusting mechanism still has research and development values.

SUMMERY OF THE UTILITY MODEL

Based on above, the utility model provides a simple and easy manual waist holds in palm structure through designing simple and easy structure, satisfies basic use needs, reduce cost, alleviates the quality.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a simple and easy manual waist holds in palm structure, be located between seat skeleton and the seat foam layer, it includes the backboard, a fixed base, X shape support frame and twist grip, the fixing base is violently located on the seat skeleton, and be located the back of backboard, twist grip sets up in the one end of fixing base, and it is rotatory to enable manual drive, the stroke groove has been seted up on the fixing base, the part of twist grip's stretching into the stroke groove is provided with the thread tooth, X shape support frame is articulated to be formed by two gangbar middle parts, the first end of a gangbar articulates on the fixing base, the articulated rack that has on the first end of another gangbar, the rack is located the stroke groove and cooperates the transmission with the thread tooth, the second end of two gangbars all acts on the back of backboard, change the cross angle of two gangbars through drive twist grip, and then adjust the backboard.

In particular, the second ends of both linkage rods are in abutting contact with the back of the backboard.

In particular, the second end of one of the linkage rods is hinged to the backboard and the second end of the other linkage rod is in abutting contact with the back surface of the backboard.

In particular, the axial direction of the rotating handle, the length direction of the stroke groove and the moving direction of the rack are consistent.

Particularly, a limiting ring for preventing axial movement is arranged between the rotating handle and the fixed seat.

In particular, the backboard is bent and formed according to the physiological curvature of a human body, and the backboard is directly contacted with the foam layer of the seat, and a preset ejection amount is left.

To sum up, the beneficial effects of the utility model are that, compared with the prior art, simple and easy manual waist holds in palm structure spare part is few, and is with low costs, light in weight, and it is convenient to adjust, has enough support intensity, travelling comfort and reliability, has reduced the assembly degree of difficulty, has certain economic nature and practicality.

Drawings

Fig. 1 is a schematic view of a simple manual waist support structure provided by an embodiment of the present invention.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1, the present embodiment provides a simple manual waist support structure located between a seat frame and a seat foam layer, which includes a backboard 1, a fixing base 2, an X-shaped support frame 3 and a rotating handle 4.

The fixed seat 2 is horizontally arranged on the seat framework and is positioned on the back of the backboard 1.

The backboard 1 is bent and formed according to the physiological radian of a human body, and the backboard 1 is clamped between the seat framework and the seat foam layer, is in direct contact with the seat foam layer and is reserved with a preset ejection amount.

The twist grip 4 sets up in the one end of fixing base 2, and can the manual drive rotatory, is provided with the spacing ring 8 that prevents the axial float between twist grip 4 and the fixing base 2 to make twist grip 4 only can rotate.

The fixed seat 2 is provided with a stroke groove 5, the part of the rotating handle 4 extending into the stroke groove 5 is provided with thread teeth 6, the X-shaped support frame 3 is formed by hinging the middle parts of two linkage rods, the first end of one linkage rod is hinged on the fixed seat 2, the first end of the other linkage rod is hinged with a rack 7, the rack 7 is positioned in the stroke groove 5 and is in matched transmission with the thread teeth 6, and the axial direction of the rotating handle 4, the length direction of the stroke groove 5 and the moving direction of the rack 7 are all consistent.

The second ends of the two linkage rods act on the back of the backboard 1, and the second ends of the two linkage rods can be in abutting contact with the back of the backboard 1, or the second end of one linkage rod is hinged with the backboard 1, and the second end of the other linkage rod is in abutting contact with the back of the backboard 1.

The crossing angle of the two linkage rods is changed by driving the rotating handle 4, so that the jacking amount of the backboard 1 is adjusted.

In conclusion, the simple manual waist support structure has the advantages of few parts, low cost, light weight, convenience in adjustment, enough supporting strength, comfortableness and reliability, reduced assembly difficulty and certain economical efficiency and practicability.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
