Embodiment 1

[0028] see Figure 3 to Figure 7 , the seat leg rest system shown in the figure includes a leg rest part 100 , a seat pan part 200 and a cover 300 covering the leg rest part 100 and the seat pan part 200 .

[0029] The leg rest part 100 includes a leg rest skeleton assembly 110 and a leg rest foam 120 formed on the leg rest skeleton assembly 110 , and the seat pan part 200 includes a seat pan skeleton assembly 210 and a seat pan skeleton assembly formed on the seat pan skeleton assembly 210 Seat cushion foam 220; face cover 300 is covered on leg support foam 120 and seat cushion foam 220, wherein the rear end of face cover 300 and seat pan part 200 are close to seat back part (not shown in the figure) This end of the connection.

[0030] Leg support frame assembly 110 comprises a leg support support plate 111, left and right leg support adjustment parts 112a, 112b and leg support support 113, and left and right leg support adjustment parts 112a, 112b are installed on the left...

Embodiment 2

[0042] see Figure 8 With reference to the accompanying drawings of embodiment 1 simultaneously, the difference between this embodiment 2 and embodiment 1 is that the leg rest driving mechanism is different, and the leg rest driving mechanism of this embodiment includes a motor 510a and a crank linkage mechanism, and the motor 510a is installed on On the bottom surface of the seat frame 210, one end of the crank 521a in the crank-link mechanism is connected to the output shaft of the motor 510a, the other end of the crank 521a is hinged to one end of the connecting rod 522a, and the other end of the connecting rod 522a is connected to the cover on the one hand. The pull rod 610 is connected, on the other hand, it is also connected with the rear end of the leg support bracket 113 through a fastener.

[0043] The rest of this embodiment is the same as embodiment 1.

[0044] The working principle of this embodiment is as follows:

[0045] When the leg rest part 100 needs to be ...

Abstract

The invention discloses a seat leg support system. The seat leg support system comprises a leg support part, a seat disc part and a cover wrapping the leg support part and the seat disc part. The leg support part is driven by a leg support drive mechanism to move front and back relative to the seat disc part. The leg support drive mechanism is provided with a first end and a second end, and the first end and the second end move relatively. The first end of the leg support drive mechanism is connected with the leg seat disc part. The second end of the leg support drive mechanism is connected with the leg support part. One end of the cover is connected with the end, close to a seat backrest part, of the seat disc part, and the other end of the cover is connected to the second end of the leg support drive mechanism. At least one part of the cover is a telescopic part which extends under the action of external force and retracts when the external force disappears in the movement direction of the leg support part. The aim of telescoping of a cover of an existing integrated leg support system is achieved, a cover winding and unwinding mechanism of the existing integrated leg support system is not needed, the structure is simplified, and cost is reduced.

Description

technical field [0001] The invention relates to a seat leg rest system. Background technique [0002] Now people's requirements for cars have gradually shifted from the initial simple means of transportation to daily enjoyment, and the requirements for the comfort of car seats are also getting higher and higher. Leg rests are installed in some mid-to-high-end car seats. By adjusting the length or angle of the cushion, good contact with the thighs can be maintained, and more parts of the legs can be supported to improve ride comfort. [0003] The current leg rest system is divided into two types. One leg rest system is that the seat cushion is composed of the leg rest part and the seat pan part. The leg rest part and the seat pan part adopt a split design. The leg rest of this split design is in contraction In the normal state, there will be a groove between the seat plate and the leg rest, which makes the surface of the entire seat cushion not simple and beautiful. This gro...
