Tripping device for slide rail of vehicle seat

The present invention relates to a trip device, and more particularly to a trip device for a slide rail of a vehicle seat.

In order to allow the car seat to adjust the position back and forth, the seat must be slid on a pair of slide rails, and the buckle is used to lock the adjusted position; when it is to be adjusted again, it is pulled by the hand using the unlocker. To unlock the buckle state of the buckle, and when adjusting the desired position, release the force applied to the unlocker, return the buckle to the buckle state and lock the position adjusted by the user again.

The existing unlocker generally includes a handle and a fixing bracket. However, the connection structure between the handle and the fixing bracket and the unlocking structure are designed to meet the unlocking requirements, which are complicated, resulting in cumbersome assembly and production processes. Not only is the cost high, but it is not conducive to the rapid implementation of production.

Moreover, many of the connection structures of the existing unlockers are welded, and there is a potential risk factor of instability in the welding, which affects the safety of the vehicle seat.

In three cases, the handle has a closed end and an open end opposite to each other, and the open end is provided with a plastic member, so that the handle can use the plastic member to drive the buckle. However, the handle and the buckle are made of metal. The connection between the metal handle and the buckle is made by using plastic parts. This will make the plastic parts prone to improper extension or damage, which will result in ineffective control of the buckle. The lack of action.

In addition, the unlocker can be used to freely adjust the position of the seat on the slide rail. However, when the vehicle encounters a collision and the body collapses, the collapsed body often touches the handle and unlocks. The unlocked seat is flushed toward the front of the vehicle, which makes it easier for the occupant to hit the vehicle body (such as the instrument panel) and has a higher risk.

Therefore, how to design a novel that can improve the above-mentioned defects is a major issue that the creators of this case want to solve.

The purpose of the present invention is to provide a trip device for a slide rail of a vehicle seat, which is simplified and designed to make assembly and production processes simpler and easier, thereby facilitating rapid production. Can reduce costs.

The buckle structure 3 will remain snapped between the upper rail 1 and the lower rail 2 to form a buckle state; when the driven portion 31 is lifted, the buckle state of the buckle structure 3 will be released, so that the upper rail 1 It can slide relative to the lower rail 2.

The unlocking device 500 is used to control the buckle structure 3 to unlock the buckle state thereof, the trip device 500 includes the fixed frame 5 and the control structure C, and the control structure C can be set to one or two, in two control In the case of the structure C, it is fixed to the upper rail 1 respectively. Further, in the present embodiment, the two control structures C are described as an example, but the description will not be repeated, and only one of the control structures C will be described below.

As shown in FIG. 1 and FIG. 2, the fixing frame 5 is fixed to the upper rail 1 in an arbitrary manner, and is fixed in a screwing manner in the embodiment, and the fixing bracket 5 can also have a second through hole 51 and a constant hole 52. Preferably, a third through hole 53 is also defined. The second through hole 51 is located between the through hole 52 and the third through hole 53.

The control structure C comprises a bracket 6, a control rod 7 and an elastic member 8. The control rod 7 can be of any shape. In the present embodiment, the U-shaped (see FIG. 1 ) is taken as an example for illustration. Therefore, a U-shaped rod body 71 and two connections integrally formed from both ends of the rod body 71 are integrally formed. The end portion 72; preferably, the connecting end portion 72 is further provided with a second through hole 721 corresponding to the third through hole 53. Since the two connecting end portions 72 are identical, only one of the connecting end portions 72 will be described below in order not to repeat the description.

The bracket 6 is rotatably coupled to the mounting bracket 5 in any manner and has a limiting space 64. In the present embodiment, the following description will be described as an example.

The bracket 6 includes a first protrusion 62 and a second protrusion 63 integrally extending from the frame body 61. The first protrusion 62 and the second protrusion 63 are opposite to each other, so that the frame body 61, The aforementioned limiting space 64 can be formed between the first convex portion 62 and the second convex portion 63.

The frame body 61 defines a first through hole 611 and an opening 612. Preferably, a first through hole 613 is defined in the frame body 61. The first through hole 611 is located between the opening 612 and the first through hole 613. The first through hole 611 corresponds to the second through hole 51, and the opening 612 corresponds to the through hole 52. The first through hole 613 corresponds to the second hole. The through hole 721 and the third through hole 53.

Accordingly, the first pivoting member 65 can be pivotally connected to each other by the first pivoting member 65. In detail, the first pivoting member 65 corresponds to the first through hole 611 and the second through hole 51. The pivoting enables the bracket 6 to rotate relative to the fixed frame 5 with the first pivoting member 65 as an axis. The first pivoting member 65 can be a pivot or a riveting pin, which is not limited in this creation.

As for the connecting end portion 72 of the control lever 7, it is correspondingly inserted and limited by the aforementioned limiting space 64, so that the connecting end portion 72 can be positioned on the bracket 6 accordingly. As shown in Fig. 1, in this way, the two connecting ends 72 of the control rod 7 are respectively positioned on the two brackets 6, thereby being combined into a large U-shaped pulling lever member (not labeled with the symbol).

As shown in Figures 3a and 3b, the elastic member 8 can be elastically coupled between the bracket 6 and the slide rail 100 in any manner. In this embodiment, the elastic member 8 is sleeved on the first pivoting member 65. The elastic member 8 further has an end 81 and an other end 82. One end 81 of the elastic member 8 is connected through the opening 612 and the through hole 52 (or Interfering with the lower rail 2 of the slide rail 100, the other end 82 of the elastic member 8 is connected (or interferes) with the first convex portion 62 of the bracket 6, in particular connected (or interfered with) from the first convex portion 62. A protruding plate (not labeled with a symbol) that is integrally protruded.

In this way, when the bracket 6 is rotated in the counterclockwise direction (based on FIG. 3a) with the first pivoting member 65 as the axis, the elastic member 8 relatively generates an elastic restoring force; with this elastic restoring force, it can be forced The bracket 6 is rotated in the opposite direction (ie, clockwise direction) to the original position with the first pivoting member 65 as an axis.

As shown in FIG. 4 and FIG. 5, respectively, a cross-sectional view and a side view of the creative unlocking device 500 in a static state presented when the user has not yet pulled the control lever 7 with the hand upward. At this time, the driven portion 31 of the snap structure 3 has not been depressed by the bracket 6, and thus is held in a buckled state between the upper rail 1 and the lower rail 2.

As shown in FIG. 6 and FIG. 5, FIG. 6 is a schematic side view of the unlocking device 500 in the unlocked state. When the user pulls the control lever 7 with the hand upwards, the control lever 7 rotates the bracket 6 against the first pivoting member 65 as a shaft, so that the driving portion 614 located at the rear end of the bracket 6 is pressed downward. The portion 31 further unlocks the buckle state of the snap structure 3 so that the upper rail 1 can slide relative to the lower rail 2, that is, the position of the seat on the slide rail 100 can be adjusted.

When adjusting to the desired position, as long as the user releases the force applied to the control rod 7, the elastic restoring force of the elastic member 8 can be utilized to cause the bracket 6 to rotate the control rod 7 clockwise to the original position.

As shown in FIG. 2 and FIG. 3a, the inventive trip device 500 can further ensure that the trip device 500 does not cause a trip when the vehicle body collapses due to a collision when the vehicle encounters a collision, as described below.

As shown in the figure, the connecting end portion 72, the frame body 61 and the fixing frame 5 can be pivotally connected to each other by a second pivoting member 73. Specifically, the second pivoting member 73 corresponds to the first through hole 613. The second through hole 721 and the third through hole 53 are pivotally connected to rotate the connecting end portion 72 of the control rod 7 with the second pivoting member 73 as an axis. The second pivoting member 73 can be a pivot, a latch, or a pull stud.

At this time, the first convex portion 62 and the second convex portion 62 of the bracket 6 are blocked in the same rotational direction of the connecting end portion 72, that is, the connecting end portion 72 is blocked by the second pivoting member 73. In the rotational direction of rotation, in other words, in this case, the connecting end portion 72 will be restrained by the first convex portion 62 and the second convex portion 63 from being rotatable.

Then, in order to rotate the connecting end portion 72 in only one direction, the first convex portion 62 and the second convex portion 63 of the bracket 6 respectively define a first notch 621 and a second notch 631, and the second pivoting member The pivotal position of the 73 is located between the first notch 621 and the second notch 631, so that the first protrusion 62 and the second protrusion 63 restrict the connection end 72 to only open the first notch 621 and the second notch toward the opening The direction of the 631 is rotated, that is, it can only be rotated clockwise (see Figure 7).

As shown in FIG. 7 and in conjunction with FIG. 5, FIG. 7 is a side view of the control rod 7 rotated about the second pivoting member 73 as an axis. When the vehicle encounters a collision, the collapsed body will touch the control lever 7, but since the bracket 6 is provided with the first notch 621 and the second notch 631, after the control lever 7 is touched, only The connecting end portion 72 is rotated in the direction in which the first notch 621 and the second notch 631 are opened (i.e., clockwise), and cannot be rotated in the counterclockwise direction. The connecting end portion 72 that rotates in the clockwise direction does not drive the bracket 6, so that the buckled state of the buckle structure 3 is not released.

It should be noted that if the connecting end portion 72 rotates in the counterclockwise direction, the bracket 6 will be driven to be disengaged, so that the first convex portion 62 and the second convex portion 63 are provided to be blocked, so that the connecting end portion 72 is regardless of Nothing will rotate in the counterclockwise direction.

Therefore, the direction in which the connecting end portion 72 is forced to rotate by the control body 7 due to the collision of the vehicle body (clockwise direction) is opposite to the direction in which the connecting end portion 72 is used to release the buckle structure 3 (counterclockwise direction).

As shown in FIG. 1 , FIG. 2 and FIG. 4 to FIG. 6 , in addition, a driving portion 614 is integrally formed in an arbitrary manner at the tail end of the bracket 6 or near the trailing end, and is opened in the frame body 61 in this embodiment. The slotting is described as an example. Therefore, when the bracket 6 is made of a metal material, the driving portion 614 is also made of a metal material.

The driven portion 31 of the buckle structure 3 extends correspondingly to the position of the driving portion 614, so that the bracket 6 can directly press or lift the driven portion 31 via the driving portion 614.

In summary, the present invention has the following functions as compared with the prior art: the first pivoting member 65 is pivotally connected between the bracket 6 and the fixing frame 5, so that the bracket 6 is rotatably connected to the fixing bracket 5, The elastic member 8 is just sleeved and positioned on the first pivoting member 65 and can elastically act between the bracket 6 and the fixing frame 5 in a simple manner; in addition, the connecting end portion 72 of the control rod 7 is inserted and limited. In the limiting space 64 of the bracket 6, so that the control lever 7 can be stably positioned on the bracket 6 with a simple structure, so that the lever 7 will be able to accurately control the motion of the bracket 6.

Moreover, the second pivoting member 73 can be further pivoted between the control rod 7, the bracket 6 and the fixing frame 5, so that the connecting end portion 72 of the control rod 7 can also be connected to the bracket 6, thereby further improving the control. The stability of the connection between the rod 7 and the bracket 6.

In addition, the present invention has other functions: by the second pivoting member 73, the connecting end portion 72 of the control rod 7 is rotatably coupled to the bracket 6, and the first portion for limiting the connecting end portion 72 A first notch 621 and a second notch 631 are respectively formed in a convex portion 62 and a second protruding portion 63, so that the connecting end portion 72 can only rotate in a direction in which the first notch 621 and the second notch 631 are opened (for example, The clock direction) cannot be rotated in the other direction opposite to the direction (for example, counterclockwise), and the design is only released in the other direction. Therefore, when the vehicle encounters a collision, the body collapses. At this time, it will be ensured that the trip device 500 is not tripped by the collided body, thereby ensuring the safety of the occupant sitting on the vehicle seat.

In addition, the driving portion 614 is integrally formed on the bracket 6 so that the driving portion 614 can be made of a tough material (for example, metal) together with the bracket 6. Therefore, the driving portion 614 can directly drive the buckle structure 3 to be moved. Since the portion 31 does not undergo improper expansion or damage, the action of the buckle structure 3 can be effectively controlled.

The above is only a preferred and feasible embodiment of the present invention, and thus does not limit the scope of the patent of the creation, and the equivalent structural changes that are made by using the present specification and the contents of the schema are all included in the creation. Within the scope of the rights, it is given to Chen Ming.
