The invention relates to a tank chain type leg support extending mechanism. The tank chain type leg support extending mechanism comprises a main body structure, an extending structure and a coating structure, wherein the main body structure comprises a foundation mechanism, a fixed bracket and a driving mechanism, wherein the fixed bracket and the driving mechanism are mounted and fixed on the foundation mechanism; the extending structure comprises an extending bracket, a track mechanism and a tank chain assembly, wherein the extending bracket is connected with the driving mechanism and is fixedly connected to the fixed bracket in a slidable manner; the track mechanisms are mounted and fixed on the two sides of the extending bracket; the tank chain assembly is mounted and fixed on the extending bracket through the track mechanisms; one end of the tank chain assembly is connected with the main body structure; and the coating structure comprises a surface sleeve covering the main body structure and the tank chain assembly, wherein the two ends of the surface sleeve are correspondingly connected with the main body structure and the tank chain assembly. The tank chain type leg supportextending mechanism forms a whole body and has the advantages that the appearance beauty is good, the cleaning is convenient, and clothes of passengers cannot be clamped.
Description
technical field [0001] The present invention relates to a car seat, and more particularly to a tank chain leg rest extension mechanism. Background technique [0002] As cars gradually become people's daily travel tools, the comfort of car seats has also received more attention. In order to achieve a comfortable effect and make the seat and the human body in a suitable contact state, adjusting the length of the seat cushion to provide more support for the legs is an important research direction. [0003] The currently proposed leg support extension mechanisms can be divided into thigh leg support extension mechanisms and calf leg support extension mechanisms in terms of supporting objects. The thigh support extension mechanism generally has good integrity, but the mechanism is relatively complicated, the stroke is short, and it is easy to squeeze and rub on the inner side of the cover. The extension mechanism of the calf leg support generally exists in a split type. The joi...
