Method used

The difference with 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 manual drive parts such as crank handles can be installed on the intermediate link 30 The opening and retracting of the leg support mechanism 2 can be realized by driving the intermediate connecting rod 30 to rotate forward and reverse. 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, then 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 retrac...

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.

Example Embodiment

[0048] Example 2

[0049] In addition, a variety of drive modes are available for hand electric function.

[0050] The difference with example one is that the middle linkage 30 is provided with a rotating part, the rotating part is exposed outward through the articulator, the fixing bracket, the middle linkage 30 can be driven by manual driving components such as a rocker on the middle linkage 30 to achieve the opening and retraction of the leg support mechanism 2. Preferably the middle connecting rod 30 is a spline shaft structure, the spline shaft is matched with the articulation, and the rake is provided with a latch groove, then the end of the rever and the intermediate linkage 30 can be equipped to drive the intermediate linkage 30 to rotate, to achieve the opening and retraction of the leg support mechanism 2. As a result, manual functions are further added, providing more configuration options for car companies or users.
