Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1 and 2, an integrated footrest device for a car seat back relates to the following main components: bracket component 1, foot layer board 2, swing arm subassembly 3 and actuating mechanism 4.

The bracket assembly 1 is disposed inside the backrest a, and the bracket assembly 1 includes two supporting members 1a symmetrically disposed inside the backrest a, and a rotating shaft 1b rotatably disposed between the two supporting members 1 a.

The swing arm assembly 3 comprises an outer swing arm 3a, an inner swing arm 3b and a support lug 3c which are rigidly connected into a whole, the outer swing arm 3a is of an arc-shaped structure, the outer end of the outer swing arm is fixedly assembled on the foot supporting plate 2, the inner swing arm 3b is provided with an arc-shaped section 3b1 and an installation section 3b2 which is deviated to one side relative to the arc-shaped section 3b1, the installation section 3b2 is deviated and arranged to improve the structural strength of the inner swing arm 3b, the end part of the installation section 3b2 is welded and fixed with the rotating shaft 1b, and based on the installation relation, the foot supporting plate 2 can rotate relative to the supporting part 1a through the swing arm assembly 3.

In the present embodiment, the driving mechanism 4 is preferably an electric push rod, the upper end of the electric push rod is hinged in the backrest a, the lower end of the electric push rod is hinged on a support lug 3c, the support lug 3c is fixedly connected on one side of the inner swing arm 3b far away from the installation section 3b2, and the up-and-down telescopic movement of the electric push rod can enable the whole swing arm assembly 3 to rotate relative to the supporting component 1a, namely: the electric push rod is contracted upwards to enable the foot supporting plate 2 to be turned backwards to the state shown in fig. 4, so that the feet of passengers in the back row can be conveniently placed; the electric push rod extends downwards to enable the foot supporting plate 2 to rotate forwards to the state shown in figure 3, so that the foot supporting plate 2 is folded.

As shown in fig. 1 again, electric putter arranges along back A's direction of height, and so design, the inner space that can make full use of back skeleton, the back space that occupies still less for whole inside drive module can not occupy too much back skeleton space, is favorable to realizing slim design, can not additionally increase back thickness.

As shown in fig. 2, the support member 1a is provided with a first stopper portion 1a1 and a second stopper portion 1a2, and the rotation range of the inner swing arm 3b is limited between the first stopper portion 1a1 and the second stopper portion 1a 2. When the middle and rear row passengers use the foot rests, the seat can be integrally moved forwards in an electric control mode, and then the backrest A is rotated to a slightly forward inclined posture, so that a space can be made free for the users to put feet on the foot supporting plates 2 conveniently. Since the backrest A is slightly inclined forward when the footrest is used, the tilting angle of the footrest 2 with respect to the backrest A should also exceed 90 degrees in order to keep the footrest 2 horizontal. When the sole plate 2 expandes to use, sole plate 2's dead weight and user's low limbs weight all transmit to the back skeleton through supporting component 1a on, the following three kinds of technical means that this embodiment adopted all help guaranteeing the support intensity of whole foot rest, and one is: the supporting component 1a is provided with a flanging 1a3 at the position corresponding to the first limiting part 1a1 and the second limiting part 1a2, and the flanging 1a3 can increase the stress area; the second is that: a reinforcing member 1c is connected between the support member 1a and the backrest A; the third step is that: the mounting section 3b2 of the inner swing arm 3b is formed offset to one side with respect to the arc-shaped section 3b 1.

As shown in fig. 4, further, the arc section 3b1 is adapted to the curvature of the outer swing arm 3a, and the two are detachably assembled and connected, after the foot rest board 2 is turned backwards, the arc section 3b1 and the outer swing arm 3a are exposed at the rear side of the backrest, at this time, the foot rest board 2 can be freely disassembled and assembled, so that the user can select foot rest boards 2 of different styles or shapes according to personal preference, and the product interchangeability is better.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
