The invention discloses a seat with a stepless adjusting thigh support. The seat comprises a cushion half basin, a cushion foaming assembly, a thigh support foaming assembly, a sliding plate assemblyand a driving assembly. The driving assembly comprises an air bag and an inflation and deflation control mechanism; an organ fold structure is arranged between the front end face and the rear end faceof the air bag, the air bag is located between the cushion foaming assembly and the thigh support foaming assembly, the rear end face of the air bag and the front end face of the core portion of thecushion foaming assembly are relatively fixed, and the inflation and deflation control mechanism can inflate or deflate the air bag. The thigh support foaming assembly abuts against the front end faceof the air bag under the action of reset force. Stepless adjustment of the forward extending distance of the thigh support foaming assembly is achieved; and the thigh part, located between the thighsupport foaming assembly and the cushion foaming assembly, of the passenger can also be supported by the inflated and expanded air bag, so that the riding comfort of the passenger can be improved, andthe influence of a gap between the thigh support foaming assembly and the cushion foaming assembly on the attractiveness of the seat can be eliminated.

    本发明公开了一种具有无级调节大腿托的座椅,包括坐垫半盆、坐垫发泡总成、大腿托发泡总成、滑板总成和驱动总成;驱动总成包括气袋和充放气控制机构;气袋的前端面与后端面之间为风琴摺结构,气袋位于坐垫发泡总成与大腿托发泡总成之间,且气袋的后端面与坐垫发泡总成的芯部前端面相对固定,充放气控制机构能够对气袋进行充气或放气;大腿托发泡总成在复位力的作用下抵顶在气袋的前端面上。本发明实现了大腿托发泡总成向前伸出距离的无级调节,且乘客位于大腿托发泡总成与坐垫发泡总成之间的大腿部位也能够被充气膨胀的气袋所承托,既能提升乘客的乘坐舒适性,又能消除大腿托发泡总成与坐垫发泡总成之间的间隙对座椅美观性的影响。
