Embodiment 1

[0041] Embodiment 1: as figure 1 As shown, a car seat forward folding adjustment device includes a seat pan frame 1, a backrest frame 2 and a rotary handle 3, and a slide rail mechanism 4 connected to the floor of the compartment. The slide rail mechanism 4 includes a fixed rail 41 and a slide rail 42. The slide rail 42, the rotary handle 3, the seat pan frame 1 and the backrest frame 2 jointly form a four-bar linkage mechanism. The handle 3 is connected to the seat basin frame 1, the seat pot frame 1 and the backrest frame 2, the backrest frame 2 and the slide rail 42, and the slide rail 42 is connected to the rotary handle 3 through hinges respectively; a locking mechanism includes a slide rail lock 5, a slide rail Lock 5 is made of spring latch or elastic clip or other not only convenient locking but also convenient release mechanism, and one end thereof is connected to the lower end of backrest frame 2, and the other end is releasably connected with the fixed track 41 tha...

Embodiment 2

[0046] Embodiment 2: A torsion spring 8 is provided at the hinge part where the seat pan frame 1 and the backrest frame 2 are connected. The torsion spring 8 is arranged on the rotating shaft of the seat back 1, and provides return power when the seat back is adjusted, so that the backrest can be returned easily. The rotating shaft is also the hinge shaft. All the other structures are with embodiment 1. see Figure 4 , Figure 5 and Figure 6 .

Embodiment 3

[0047] Embodiment 3: A coil spring 7 is provided at the hinge connection between the seat pan frame 1 and the slide rail 42, the coil spring 7 is a planar scroll spring with variable stiffness, and the outermost end of the planar scroll spring with variable stiffness has a certain stiffness Lower buffer segment. The installation method of the planar scroll spring is that the outer end is fixed and the inner end is turned. All the other structures are with embodiment 1. see figure 1 .

Abstract

The invention relates to an automobile seat adjusting device capable of being tilted forward and folded, and provides a seat device. The automobile seat adjusting device can be tilted forward and folded and moved forward to release a space as large as possible to enable rear-row staff to come in and go out, and the operation of the automobile seat adjusting device is labor-saving. The automobile seat adjusting device comprises a seat basin framework, a backrest framework, a rotating handle, and a sliding rail mechanism connected to floors of a compartment, wherein the sliding rail mechanism comprises fixed rails and sliding rails; a four-bar mechanism is jointly formed by the sliding rails, the rotating handle, the seat basin framework and the backrest framework; the rotating handle is connected with the seat basin framework through a hinge, the seat basin framework is connected with the backrest framework through a hinge, the backrest framework is connected with the sliding rails through hinges, and the sliding rails are separately connected with the rotating handle through a hinge; and the automobile seat adjusting device is provided with a locking mechanism.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of car seat structures, and in particular relates to a seat device that can be folded forward and moved forward. [0003] Background technique: [0004] The car seat quick entry system in the prior art mainly unlocks the backrest through a cable, and uses the turning angle of the backrest to drive the unlocking slide rail. The rear row personnel that this structure can provide is limited in and out of space, is inconvenient to get on and off the car, and the assembly process is complicated, the space that can vacate is extremely limited, and comprehensive effect is not good. [0005] The prior art also has an improved car seat easy-entry structure. For example, Chinese patent application number: 201110274054.3, the Chinese patent application titled "Seat Back Release System for Easy-to-Entry Car Seat", discloses a car seat Quick access structure, the seat back motion controller of this application is...
