Embodiment 2

[0049] In addition, a variety of driving methods are provided to realize the manual function.

[0050] The difference from Embodiment 1 is that the intermediate link 30 is provided with a rotating part, and the rotating part is exposed to the outside through the hinge and the fixed bracket, and the intermediate link can be driven by manual drive components such as a crank handle installed on the intermediate link 30. The forward and reverse rotation of the rod 30 can realize the opening and retraction of the leg rest mechanism 2 . Preferably, the intermediate connecting rod 30 is a spline shaft structure, the spline shaft is matched with the hinge, and the crank handle is provided with a spline groove, so the end of the crank handle and the intermediate connecting rod 30 can be assembled to drive the intermediate connecting rod 30 to rotate. Realize the opening and retracting of the leg rest mechanism 2. As a result, manual functions have been further added to provide car com...

Embodiment 3

[0052] Also disclosed is a car seat, including the leg support mechanism 2 in the first embodiment and the second embodiment; thus, the car seat has a leg support function.

Abstract

The invention discloses a seat leg support mechanism and a seat. A hinging device is mounted on a seat framework; the lifting arm is movably arranged on the seat framework by virtue of a hinging device; the lifting arm is provided with a first sliding holding part and a second sliding holding part; one end of the first connecting rod is hinged to the seat framework; the first sliding part and the second sliding part are located between the two lifting arms, and the first sliding part partially penetrates through the first sliding maintaining part and then is hinged to the end, away from the seat framework, of the connecting rod; the two ends of the second sliding component are arranged in the second sliding holding part in a sliding manner; the first sliding component and the second sliding component are provided with a first sliding left-right direction holding part and a fourth sliding holding part respectively, and the first sliding left-right direction holding part and the fourth sliding holding part are both perpendicular to the extending direction of the lifting arm; the ends, close to the seat framework, of the second connecting rod and the third connecting rod are hinged to the lifting arm, and the ends, away from the seat framework, of the second connecting rod and the third connecting rod are movably connected into the fourth sliding maintaining part. And the driver drives the lifting arm to rotate.

Description

technical field [0001] The invention belongs to the technical field of automobile seats, and in particular relates to a seat leg support mechanism and a seat. Background technique [0002] With the continuous improvement of people's requirements for the comfort and space of passenger cars, people put forward higher requirements for the comfort of seats. Leg rest mechanisms are provided on many models to reduce the feeling of dangling legs by supporting the lower legs of the human body. , thereby reducing leg discomfort during long-term driving and improving ride comfort. [0003] The seat leg rest adjustment device disclosed in the prior art mainly includes a recliner and a link mechanism, wherein the fixing part of the recliner is used to connect with the fixing part of the seat, and the connecting rod The power input rod of the mechanism is connected with the rotary output part of the recliner, and the power output rod of the linkage mechanism is used to connect with the ...
