Description

Seat rail assembly

This creation is about car seats, especially an easy-to-assemble seat rail assembly.

A typical front seat of a car is mounted on the floor in the compartment by a set of slide rails, so that the driving or co-pilot of the front seat can adjust the position of the seat by the slide rails. In order to facilitate the fixing of the position of the seat, a fixing mechanism is usually added to the sliding rail to lock the sliding rail, and the fixing mechanism is connected with a pull rod for driving or the first driving to pull the release rail.

In general, the slide rail includes an inner groove and an outer groove in a sleeve configuration. When installing the seat, first lock one of the inner and outer slots on the floor in the compartment, then fit the inner and outer slots, and finally lock the seat to the inner and outer slots. Complete the installation in one. Therefore, during the installation process, when the inner groove and the outer groove slide relative to each other, the external fixing mechanism interferes with the adjacent outer member to make the installation inconvenient. Furthermore, the fixing mechanism also needs to change the design for different models and seats to avoid the sliding stroke being hindered. In summary, the existing car seat slides are inconvenient to assemble and have poor compatibility.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The configuration of each of the slide rails 10 is the same, and therefore will be described later with a single slide rail 10.

Referring to FIG. 2 and FIG. 3, the inner groove 100 is a long groove body with a U-shaped cross section, and the inner wall of the inner groove 100 is provided with a fixing hook 110, and the inner groove 100 is bent inwardly to form a pivot frame 120 by punching. The two side edges of the inner groove 100 are outwardly bent to form a sliding groove 101 extending longitudinally along the inner groove 100, and a plurality of perforations 102 are formed in one side of the inner groove 100. In this embodiment, each of the perforations 102 The chute 101 can be penetrated through the side, but the creation is not limited thereto.

The outer groove 200 is a long groove body with a U-shaped cross section, and the outer groove 200 is slidably sleeved outside the inner groove 100, and the inner groove 100 and the outer groove 200 are relatively closed and sleeved. The two side edges of the outer groove 200 are bent inwardly to form a flange 201 extending longitudinally along the outer groove 200. Each flange 201 corresponds to each of the sliding grooves 101 on the inner groove 100, and each flange 201 is slidably The slit 101 is correspondingly disposed in the inner groove 100. The inner wall of the outer groove 200 is formed with a plurality of convex teeth 210. The convex teeth 210 are preferably formed at the edge of the flange 210. The convex teeth 210 are arranged along the longitudinal interval of the outer groove 200 at any adjacent two convex teeth 210. A tooth groove 220 is formed therebetween.

Referring to FIG. 2 to FIG. 6 , the claw 300 is disposed in the inner groove 100 and pivoted to the inner groove 100. The claw 300 is pivotally connected to the pivot frame 120 by a shaft 320 to be disposed in the inner groove 100, and the shaft is disposed. The pivot frame 120 is disposed along the longitudinal direction of the inner groove 100. The claw 300 includes a plurality of claws 310 arranged side by side, and the shaft 320 is sleeved with a return spring 330 to push the claws 300 toward the protruding teeth 210, thereby causing the claws 310 to pass through the corresponding through holes 101. The inner groove 100 hooks at least a portion of the protruding teeth 210 to fix the inner groove 100 and the outer groove 200. The claws 310 are respectively hooked into one of the slots 220 to hook the protruding teeth 210. The through hole 102 in the inner groove 100 penetrates the sliding groove 101 to allow the claw portion 310 to penetrate the sliding groove 101 to be firmly hooked in the tooth groove 220.

The driving link 400 is disposed in the inner slot 100 and pivoted to the inner slot 100. The two ends of the driving link 400 are a fixed end 401 and a driving end 402, respectively. The actuating end 401 of the drive link 400 is disposed corresponding to the hook 300, and the drive end 402 of the drive link 400 extends through one end of the inner slot 100. A pair of coaxially disposed cams 410 are disposed on the outer surface of the driving link 400. Each of the tenons 410 is formed in a punching manner on a side surface of the driving link 400, and the pair of tenons 410 are pivotally connected to the inner groove 100. A bracket 420 is disposed inside the middle portion of the driving link 400, and the bracket 420 is disposed adjacent to the pair of tenons 410. The middle portion of the driving link 400 defines a through opening 403, and the fixing hook 110 on the inner groove 100 is received in the opening 403 of the driving link 400.

The elastic return lever 500 is disposed within the inner slot 100. In the present embodiment, the elastic reset lever 500 is preferably disposed through the drive link 400 and spans over the bracket 420. The two ends of the elastic reset rod 500 are respectively a fixed end 501 and a free end 502. The fixed end 501 of the elastic return rod 500 is hooked to the fixing hook 110 on the inner wall of the inner groove 100 through the opening 403 of the driving link 400. The free end 502 of the resilient return lever 500 hooks the drive end 402 of the drive link 400. The elastic return lever 500 is elastically deformed by being pressed by the bracket 420, thereby generating a restoring force to the driving end 402 of the drive link 400 to position the drive link 400 in an initial position.

The two ends of the release lever 20 are respectively connected to the driving end 402 of the driving link 400, thereby connecting the driving links 400 of the two sliding rails 10 in series.

Referring to FIGS. 2, 3, 6, and 7, when the drive link 400 is in the initial position, the actuating end 401 of the drive link 400 is adjacent to and spaced apart from the pawl 300. Referring to FIGS. 8 and 9, when the release lever 20 is pulled, the release lever 20 can drive the drive link 400 of each slide rail 10 to pivot at the same time, so that the actuation end 401 of each drive link 400 abuts the corresponding claw. 300. When the release lever 20 continues to be pulled, the release lever 20 can drive the drive links 400 to continue to pivot, thereby pushing the respective pawls 300 to pivot. The pivoting of each of the claws 300 enables the claws 310 of the respective claws 300 to be withdrawn from the slots 220 and disengaged from the protruding teeth 210, thereby releasing the outer slots 200 so that the inner slots 100 and the outer slots 200 of the slide rails 10 can be relatively slippery. Move, thereby releasing the slide rails 10 at the same time.

The seat rail assembly of the present invention has a simple structure of the hook 300 of the slide rail 10, the drive link 400 and the elastic return lever 500, and is easy to assemble into the inner groove 100, and then the inner groove 100 is inserted into the outer groove 200. The slide rail 10 is assembled. Moreover, the seat rail assembly of the present invention has a simple shape of the slide rail 10, and the hook 300, the drive link 400 and the elastic return lever 500 are accommodated in the inner groove 100, and the outer surface of the slide rail 10 is not convex. The structural member, therefore, does not interfere with its adjacent external members when the seat 20 and the compartment 40 are locked, and is easy to install, and has better compatibility with different models and seats 20.
