Automobile seat skeleton

Abstract

The invention discloses an automobile seat skeleton. The automobile seat skeleton comprises a seat frame skeleton and a backrest skeleton. The seat frame skeleton is connected with the backrest skeleton through an adjustor, and the backrest skeleton comprises a backrest back plate of a frame-shaped structure. The outer ring portion of the backrest back plate is folded forwards to form a backrest frame, and the edge of the inner ring of the backrest back plate is folded forwards to form a folded edge. The upper portion of the backrest back plate is provided with at least two headrest pipes. The headrest pipes penetrate out of the backrest frame, front demolding openings are formed in the front walls of the headrest pipes, and rear demolding openings are formed in the rear walls of the headrest pipes, wherein the front demolding openings and the rear demolding openings are arranged in a crossed mode. The automobile seat skeleton has the advantages that the strength of the backrest skeleton is enhanced, the weight of the backrest skeleton is not excessively increased, the service life of the backrest skeleton is prolonged, one-time demolding can be achieved on the headrest pipes, and the demolding technology can be simpler and more reliable. The structure of the seat frame skeleton is simple, novel and compact, the height adjusting range of the height adjuster can be enlarged, and meanwhile use is more convenient; reliable installation of parts such as the height adjuster and a seat frame side plate can be ensured.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a car seat frame. Background technique [0002] The car seat is supported by the car seat frame. The car seat frame includes the backrest frame and the seat frame frame. At present, for the original front seat backrest stamped steel frame of the car, the technicians propose to use the combination of magnesium alloy extruded pipe and stamped plate. The new semi-closed magnesium alloy backrest skeleton structure is replaced, and the structure and the two-way recliner form a closed one-piece backrest skeleton, which can achieve a weight reduction ratio of 48.8%. [0003] At the same time, the high-profile device of the car seat is installed on the side plate of the seat frame to mesh with the fan-shaped lifting tooth plate to achieve the purpose of adjusting the height of the seat frame. Due to the limitation of the installation position, the high-profile device is located The he...

Problems solved by technology

[0003] At the same time, the high-profile device of the car seat is installed on the side plate of the seat frame to mesh with the fan-shaped lifting tooth plate to achieve the purpose of adjusting the height of the seat frame. Due to the limitation of the installation position, the high-profile device is located The height adjustment range of the controller is not ideal enough to meet the needs of use

Moreover, in the traditional car seat frame side panel, when the high-profile device is installed on the seat frame side plate, the slopes on both sides of the high-profile device are unevenly distributed, and the high-profile device is fitted with one side slope, which inevitably makes the high-profile device and The slope on the other side of the side plate of the seat frame produces a large gap, so that when the gear of the high-profile device meshes with the lifting tooth plate, the transmission is difficult, and even the phenomenon of being unable to rotate occurs, which in turn affects the lifting function of the entire seat frame skeleton.
