Embodiment 1

[0082] This embodiment provides a backrest adjustment mechanism, such as figure 1 and 2 As shown, the backrest adjustment mechanism 4 includes a support adjustment part and a rotational connection part 40 .

[0083] The rotating connection part 40 includes: a first adapter 402 , a second adapter 409 , a third adapter 407 and an elastic body 408 . The first adapter 402 is arranged on the top of the support adjustment part; the surface of the first adapter 402 facing the second adapter 409 is distributed with a plurality of protrusions 411; the second adapter 409 faces the first adapter 402 A plurality of grooves 410 matching the protrusions 411 are distributed on the surface; the third adapter 407 passes through the elastic body 408 and rotates to connect the second adapter 409 and the first adapter 402; the second adapter The groove 410 on 409 abuts with the protrusion 411 on the first adapter 402 . In another embodiment of this embodiment, there are at least two protrusion...

Embodiment 2

[0087] This embodiment provides another backrest adjustment mechanism, such as image 3 As shown, the backrest adjustment mechanism 4 includes a support adjustment part and a rotational connection part 40 . The structure of the rotating connection part 40 in this embodiment is the same as the structure of the rotating connecting part 40 in the first embodiment, and will not be repeated here. The difference from Embodiment 1 is that the support adjustment part in this embodiment includes: an adjustment rod 413 and a gear adjustment part arranged on the adjustment rod 413; the gear adjustment part is a plurality of slots 414 arranged longitudinally The opening direction of 414 is consistent, and the direction of the depth of the plurality of slots 414 forms an included angle with the adjusting rod 413, such as image 3 , the angle A between the depth direction of the locking groove 414 and the adjusting rod 413 is optimally an acute angle. Such as image 3 Among them, there a...

Embodiment 3

[0089] This embodiment provides a seat with an adjustable anti-pinch backrest, such as Figure 4 As shown, in addition to introducing the structural design of the seat with adjustable backrest for anti-pinch in detail, this embodiment will also specifically introduce the specific application of the backrest adjustment mechanism 4 in the seat with adjustable backrest for anti-pinch in Embodiment 1 and the resulting benefits. benefit.

[0090] The seat with an adjustable anti-pinch backrest in this embodiment can be a recliner, a leisure chair or a single sofa, and the seat with an adjustable anti-pinch backrest includes: a recliner 1, a backrest 3 that is rotatably connected to the recliner 1, a support The main frame 2 of the lying board 1 , the support rod 5 and at least one backrest adjustment mechanism 4 .

[0091] Wherein, the main frame 2 includes: a first frame body 201 and a second frame body 202 arranged vertically; The fourth frame body 204; the third frame body 203...

Abstract

The invention discloses a backrest adjusting mechanism and a seat with a hand pinching preventing adjustable backrest. The backrest adjusting mechanism comprises a support adjusting part and a rotational connecting part, wherein the rotational connecting part comprises a first rotational connecting member, a second rotational connecting member, a third rotational connecting member and an elastic body which are arranged at the top end of the support adjusting part; a plurality of bulges or a plurality of grooves are distributed in a surface facing to the second rotational connecting member, of the first rotational connecting member; a plurality of grooves matched with the bulges or a plurality of bulges matched with the grooves are distributed on a surface facing to the first rotational connecting member, of the second rotational connecting member; the third rotational connecting member penetrates through the elastic body and is rotationally connected with the second rotational connecting member and the first rotational connecting member; the grooves are abutted with the bulges. The seat comprises a lying plate, the backrest, a main frame, support rods and two adjusting stairs as well as at least one backrest adjusting mechanism mentioned above. Due to the bulges and the grooves on the backrest adjusting mechanism, and together with the adjusting stairs, a fixed support function and a sectional adjusting function for backrest angle adjustment can be achieved, and the risk of hand pinching or compression can be avoided.

Description

technical field [0001] The invention relates to a hand-pinch anti-backrest adjustable seat, in particular to a backrest adjustment mechanism applied to the hand-pinch anti-backrest adjustable seat and a hand-pinch anti-backrest adjustable seat provided with the backrest adjustment mechanism. Background technique [0002] In the existing furniture industry, the backrest adjustment mechanism is mostly used in recliners or lounge chairs, so that the angle of the backrest of the recliner or lounge chair or single sofa can be adjusted at will. Relax on a recliner or lounge chair or armchair. [0003] In the prior art, the design of the backrest adjustment mechanism in a recliner or lounge chair or a single sofa is to tap the keyhole of the accessories welded on the backrest and the joint of the backrest adjustment mechanism on the back of the backrest, and use screws to add 2 pieces of plastic pads The piece is combined with the accessories welded on the back of the backrest and...
