Description

Technical Field

[0001] The invention relates to a car seat track, in particular to an easy-to-assemble car seat track assembly. Background Art

[0002] The present invention relates to a car seat track. A general car seat track includes an outer rail, an inner rail, and a pull rod. The inner rail is movably inserted into the outer rail, the pull rod is pivoted on the inner rail, and the pull rod is connected to a hook to hook the outer rail. By pulling the pull rod, the inner rail and the outer rail can be selectively fixed or released. Generally speaking, an elastic member needs to be connected between the inner rail and the pull rod to push the pull rod to reset and hook the hook into the outer rail. Therefore, when assembling the pull rod to the inner rail, it is necessary to first press the elastic member to overcome its elastic force before the pull rod can be pivoted to the inner rail. It is not easy for a single operator to press the elastic member and align the pull rod to pivot to the inner rail at the same time. Therefore, the existing car seat track is inconvenient to assemble, and its assembly requires a long time. Summary of the invention

DETAILED DESCRIPTION

[0020] See also Figures 1 to 3 The first embodiment of the present invention provides a car seat track assembly, which includes an outer rail 100, an inner rail 200, a pivot seat 300 and a pull rod 400. Generally speaking, a car seat is usually arranged on a pair of car seat track assemblies arranged parallel to each other and spaced apart, and the pair of car seat track assemblies share the same pull rod 400. Here, only one of the car seat track assemblies is taken as an example for description.

[0021] See also Figure 3 , Figure 6 and Figure 7 In this embodiment, the outer rail 100 and the inner rail 200 are both long strip-shaped groove bodies, and the outer rail 100 and the inner rail 200 are relatively fitted. Specifically, the inner rail 200 can be movably inserted into the outer rail 100, and at least one bearing 110 is sandwiched between the inner rail 200 and the outer rail 100, so that the inner rail 200 and the outer rail 100 can slide relative to each other in the longitudinal direction.

[0022] The outer rail 100 is provided with a plurality of tooth grooves 101 , and the inner rail 200 is provided with a hook 500 and an elastic member 520 for linking the hook 500 to movably correspond to the plurality of tooth grooves 101 . The elastic member 520 pushes the hook 500 to hook at least one of the tooth grooves 101 .

[0023] See See Figures 1 to 4 and Figures 5 to 9 The hook 500 has at least one claw 501 and the inner rail 200 has at least one claw hole 201 corresponding to the claw 501. Each claw 501 can pass through the claw hole 201 to hook one of the tooth grooves 101 and thereby lock the inner rail 200 and the outer rail 100 so that they cannot slide relative to each other. In this example, a slide bar 510 is disposed in the inner rail 200. The slide bar 510 passes through the hook 500 and the hook 500 can move along the slide bar 510 to guide the movement of the hook 500. The elastic member 520 is a cylindrical spring sleeved on the slide bar 510. One end of the elastic member 520 abuts against the protrusion on the side of the slide bar 510, and the other end of the elastic member 520 abuts against the hook 500.

[0024] See also Figure 2 , Figure 3 , Figure 5 and Figure 8The pivot seat 300 is disposed on the inner rail 200 and is provided with a reset spring arm 310. In this embodiment, the pivot seat 300 is tightly inserted into the inner rail 200 and the reset spring arm 310 extends from the pivot seat 300. At least one spring arm hook 320 extends from the side of the pivot seat 300, and the spring arm hook 320 is engaged with the inner rail 200 to fix the pivot seat 300 in the inner rail 200.

[0025] See also Figures 1 to 4 , Figures 5 to 7 , Fig.10 and Fig.11 The pull rod 400 is pivotally connected to the pivot seat 300, the pull rod 400 abuts against the hook 500, and the pull rod 400 can pivot to push the hook 500 away from the plurality of tooth grooves 101, so that the inner rail 200 can slide relative to the outer rail 100. Figure 8 and Fig. 9 The reset spring arm 310 abuts against the pull rod 400 . When the pull rod 400 is released by the user, the reset spring arm 310 can push the pull rod 400 to pivot and release the hook 500 so that the hook 500 is reset and locked to the outer rail 100 .

[0026] See also Figures 1 to 3 and Figure 5 One end of the pull rod is inserted into the inner rail 200, and the pull rod passes through the pivot seat 300 and is pivotally connected to the pivot seat 300. The pull rod 400 has a rod 410 and a pivot member 420 disposed at the end of the rod 410. In this embodiment, the rod 410 is preferably a U-shaped curved rod, and a pivot member 420 is disposed at both ends thereof to pivotally connect each pivot member 420 in the pair of automobile seat track assemblies. In this embodiment, only one end of the rod 410 corresponds to one of the automobile seat track assemblies for description.

[0027] In this embodiment, the pivot member 420 is disposed in the inner rail 200, and the pivot member 420 forms a pair of vertical walls 422 arranged at intervals, and a convex shaft 421 is protruded on one side of each vertical wall 422, and the convex shafts 421 extend opposite to each other and are respectively pivotally connected to the pivot seat 300. A push rod 422a is extended from each vertical wall 422, and each push rod 422a abuts against the hook claw 500. The pivot member 420 is provided with a clamping claw 423 for clamping the end of the rod 410. In this embodiment, the clamping claw 423 is preferably disposed at one end of the inner rail 200.

[0028] In the automobile seat track assembly device of the present invention, the pull rod 400 can be pre-assembled with the pivot seat 300 through the pivot member 420, thereby pressing the reset spring arm 310 to facilitate subsequent assembly. Then, the pivot seat 300 is placed in the inner rail 200 and the spring arm hook 320 is engaged with the inner rail 200, thereby pivoting the pull rod 400 inside the inner rail 200.

[0029] See also Fig.12The second embodiment of the present invention provides a car seat track assembly, which includes an outer track 100, an inner track 200, a pivot seat 300 and a pull rod 400. The structures of the outer track 100 and the inner track 200 are the same as those of the first embodiment, and are not described in detail here. The differences between this embodiment and the first embodiment are described in detail as follows.

[0030] A guide rod 530 is disposed on the hook 500 and penetrates the inner rail 200. One end of the guide rod 530 is connected to the hook 500, and the other end of the guide rod 530 protrudes from the outer surface of the inner rail 200. The pivot seat 300 is disposed on the outer side of the inner rail 200 and the pivot seat 300 is provided with a reset spring arm 310. The pull rod 400 is pivotally connected to the pivot seat 300, the pull rod 400 abuts against the hook 500 and the pull rod 400 can pivot to push the hook 500 away from the plurality of tooth grooves 101, and the reset spring arm 310 abuts against the pull rod 400 and can push the pull rod 400 to pivot to release the hook 500 and reset the hook 500.

[0031] The pull rod 400 has a rod 410 and a pivoting member 420 disposed at the end of the rod 410, and the pivoting member 420 is pivotally connected to the pivot seat 300. A push rod 422a extends from the pivoting member 420, and the push rod 422a abuts against an end of the guide rod 530 protruding from the inner rail 200 to thereby push the hook 500. The pull rod 400 can be pre-assembled with the pivot seat 300 through the pivoting member 420, thereby suppressing the reset spring arm 310 for easy subsequent assembly. Then, the pivot seat 300 is locked to the outer side of the inner rail 200 at a position corresponding to the guide rod 530, thereby pivoting the pull rod 400 to the inner rail 200.

[0032] The automobile seat track assembly of the present invention has a pivot seat 300 pre-assembled and connected to the inner rail 200 or the pivot rod 400, thereby pre-fixing and pressing the reset spring arm 310, and then assembling the rod 400 and the inner rail 200, which is easier to assemble than directly pivoting the rod 400 to the inner rail 200.
