Embodiment 1

[0105] like Figure 1 to Figure 3 As shown, the present embodiment provides a car seat 1 on which a leg rest device 2 is arranged. Wherein, the leg rest device 2 comprises a primary leg rest assembly 21 and a secondary leg rest assembly 22, one end of the primary leg rest assembly 21 is hinged to the front end of the seat pan of the car seat 1, and the other end of the primary leg rest assembly 21 It is slidably connected with the secondary leg rest assembly 22, so that the secondary leg rest assembly 22 can slide relative to the primary leg rest assembly 21, so that the length of the leg rest device 2 can be shortened or extended, and then it is suitable for passengers of different heights. To enhance the comfort of passengers. Through the above structure, the leg rest device 2 can be switched between the storage state and the open state: when the leg rest device 2 is in the storage state, the secondary leg rest assembly 22 slides toward the direction close to the primary le...

Embodiment 2

[0107] like Figures 4 to 6As shown, this embodiment provides a link assembly 232, which can be used to drive the leg rest device 2 in the first embodiment to rotate relative to the car seat 1 and extend forward. Of course, the link assembly 232 is not limited to be used in the above car seat 1, and can also be used in other products that need to be rotated and extended, such as wheelchairs, massage chairs, folding beds, etc. For ease of understanding, the car seat 1 installed with the leg rest device 2 is taken as an example for description. The link mechanism provided in this embodiment includes a rotating mechanism 2321 and a sliding member 2322 , wherein the rotating mechanism 2321 can rotate from a first direction to a second direction, so as to realize the rotation of the leg rest device 2 relative to the car seat 1 . In this embodiment, the first direction may be a vertical direction, and the second direction may be a horizontal direction. In other embodiments, the sp...

Embodiment 3

[0114] In order to improve the stability and integration of the connection component 2327, such as Figure 7-Figure 12 As shown, this embodiment also provides a rotating and sliding member 23, which includes a driving mechanism 231 and at least one link assembly 232 as provided in Embodiment 2, and the driving mechanism 231 is used to drive the rotating mechanism 2321 turn. The rotating mechanism 2321 is driven to rotate by the driving mechanism 231, so that the entire rotating slide-out part 23 can have a moving function while turning over, and only one driving mechanism 231 is needed to realize the turning and moving functions, thereby saving costs.

[0115] In order to make the rotating and sliding out member 23 more stable when rotating and sliding out, thereby improving the stability and service life of the rotating and sliding out member 23 . The rotating slide-out component 23 provided in this embodiment includes two link assemblies 232 , the two link assemblies 232 ar...

Abstract

The invention discloses a connecting rod assembly, a rotary sliding-out component, a leg support device and an automobile seat. The connecting rod assembly comprises a rotating mechanism and a slidingpiece. The rotating mechanism can rotate from a first direction to a second direction; one end of the sliding piece is hinged to the rotating mechanism, and the other end of the sliding piece moves in the second direction under the acting force of the rotating mechanism. By means of the structural form, a component connected with the connecting rod assembly can be achieved only by driving the double-rotating mechanism to rotate through one driving motor, a rotating function can be achieved, and the effect of the moving function can also be achieved. The connecting rod assembly is applied to the leg support device on the automobile seat, the leg support device can achieve the extending function in the turned-up state at the same time, the function can be achieved only through one driving motor, and therefore the production cost is saved.

Description

technical field [0001] The invention relates to the field of car seats, in particular to a connecting rod assembly, a rotating and sliding part, a leg support device and a car seat. Background technique [0002] With the improvement of people's living standards, the comfort requirements of car seats are getting higher and higher, and the functions of car seats are more and more valued by people. Due to the difference in the height of the passengers, the length of the legs of the passengers is different, and the same seat supports the legs of different passengers differently. In order to make the car seat suitable for passengers of different heights, the car seat leg was born. support device. [0003] There are many kinds of leg rest devices on the market, and some leg rests can be turned over, so that the leg rests can be turned over and stored at the end of the seat so that the length of the seat pan itself for supporting the legs is suitable for small passengers. Provide...
