The invention discloses a vehicle seat seamless leg support mechanism which comprises a leg support moving plate, a face sleeve, a connecting rod assembly, a leg support fixing plate, a leg support moving shielding plate and a leg support fixing shielding plate, and the cross section of each of the leg support moving shielding plate and the leg support fixing shielding plate is U-shaped. The left end and the right end of the leg support fixed shielding plate extend upwards and then are arranged on the leg support fixed plate, and the left end and the right end of the leg support movable shielding plate are located on the inner sides of the left end and the right end of the leg support fixed shielding plate. The other end of the face cover downwards bypasses the front end of the leg support moving plate and then extends backwards to be arranged on the connecting rod assembly or the seat basin through a constant-force elastic piece, and the constant-force elastic piece is in a tension state when the leg support moving plate moves; the left end and the right end of the face sleeve located on the leg support part are arranged on the leg support movable shielding plate through sliding installation structures. The whole structure is simple, and meanwhile it can be guaranteed that no leakage or face cover floating occurs when the leg support rotationally stretches out or movably stretches out or forwards stretches out after rotation.
本发明公开了一种车辆座椅无缝腿托机构,包括腿托移动板、面套、连杆组件、腿托固定板、横截面均设置为“凵”型的腿托移动遮挡板和腿托固定遮挡板,所述腿托移动遮挡板的左右两端向上延伸后设置在腿托移动板上,所述腿托固定遮挡板的左右两端向上延伸后设置在腿托固定板上,所述腿托移动遮挡板的左右两端均位于腿托固定遮挡板左右两端的内侧,所述面套的另一端向下绕过腿托移动板的前端后向后延伸通过恒力弹性件设置在连杆组件或座椅坐盆上,且恒力弹性件在腿托移动板运动时均处于拉力状态,位于腿托部分的面套的左右两端均通过滑动安装结构设置在腿托移动遮挡板上。整体结构简单,同时还能保证腿托无论是在旋转伸出、移动伸出或旋转后向前伸出时均不会出现漏缝或面套浮空的情况。
