In general, the sliding device of the seat of the vehicle is to allow the seat to be slid back and forth to adjust the position of the seat according to the passenger's body and to properly utilize the interior space.

However, in the sliding device of a conventional vehicle seat having a front and rear sliding function as described above, steel balls or roller balls provided therein are completely adhered between the seat tracks, that is, the upper track and the lower track, and thus do not make a line contact. By performing the sliding movement in the spaced apart state, it acts as a factor inducing noise and vibration during driving, especially at high speeds, and has a bad effect of halting even a small external shock to halve the riding comfort.

In addition, the locking means for controlling the sliding movement of the seat of the conventional vehicle is used provided on the side of the seat track, causing torsional deformation caused by use, so that the locking means of the locking means is often not smoothly released. In the case of a sudden external shock such as an automobile accident, the locking state of the locking means is completely released, and there is a high possibility that the lower body of the passenger is injured by being inserted into the vehicle body.

Therefore, there is a need for a sliding device for a vehicle seat of a new structure that can solve the above problems.

The present invention was created in view of the above necessity, while eliminating the space between the conventional lower track and the upper track to minimize noise and vibration when adjusting the position of the seat as well as driving the vehicle and at the same time improving the riding comfort.

Here, an elastic spring for connecting the latch and the body of the locking piece is disposed between the latch of the seat panel and the body of the locking piece corresponding to the vertical downward direction of the latch, and one end of the latch is supported on the support shaft of the seat panel. It is more preferable that the other end is fixed to and the torsion spring is installed to support the outer circumference of the front end of the operating lever so that the distance between the rear end of the locking piece and the pressing piece of the operating lever maintains a predetermined separation distance in the locked state. .

In addition, a plurality of locking grooves may be formed on the lower surfaces of the upper track and the lower track to penetrate the locking protrusions formed at the ends of the locking piece, and the number of the locking grooves of the upper track may be equal to the number of the locking protrusions. It is more preferable that the number of locking grooves of the lower track is made corresponding to the sliding movement distance of the upper track.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Of course, the scope of the present invention is not limited to the following examples and can be variously modified and implemented by those skilled in the art.

1A and 1B are perspective views of an upper track and a lower track according to the present invention, and FIG. 2 is a cross-sectional view of a combination of the upper and lower tracks of FIGS. 1A and 1B, and FIG. 3 is a sliding device of an automobile seat according to the present invention. Is a cross-sectional view showing a state fixed to the seat frame, Figure 4 is a perspective view of the locking member is coupled to the seat panel according to the present invention.

First, as shown in FIG. 3, the present invention includes a lower track 10 fixed to a bottom panel (not shown) of a vehicle and sliding inside the lower track 10 to slide along the lower track 10. Sliding movement of the upper and lower steel balls (90a, b) and the upper track 30 is placed between the upper track 30, the lower track 10 and the upper track 30 to enable the sliding movement Locking member 50 for locking the door, one end is fixed to the upper track 30, the other end is fixed to the seat frame 11 and the seat having a latch 71 and the support shaft 73 protruding on the inner surface The panel 70 is configured.

Here, the lower track 10 has an internal space that can accommodate the body of the upper track 30, as shown in Figure 1a, a predetermined bent portion, that is, the lower bent portion (10a) on the inner surface And the upper bent portion 10b is formed.

More specifically, as shown in FIGS. 1A and 1B, the lower bent portion 10a of the lower track 10 may have a position and shape corresponding to the outer surface of the lower bent portion 30a of the upper track 30. It is preferably made to have, the upper bent portion (10b) is preferably made to have a position and shape corresponding to the inner surface of the upper bent portion (30b) of the upper track (30).

2, the upper and lower bent portions 10a and b of the lower track 10 are formed at right angles, and the upper and lower bent portions 30a and b of the upper track 30 are formed at right angles. ) Is more preferably configured to have an oblique inclined surface rather than a right angle. The reason for this configuration is to provide the elastic effect in the upper track 30 that is primarily loaded to reduce vibration due to play, and secondly the upper track 30 and the steel balls 90a and b. This is to increase the support robustness (such as the anti-slip effect of the steel balls (90a, b)) to the load transmitted through the).

As shown in FIG. 2, upper and lower steel balls 90a and b are disposed between the lower track 10 and the upper track 30 having the upper and lower bent portions 10a, b / 30a, b. Is published.

That is, the lower steel ball 90a makes linear contact with the inner surface of the lower bent portion 10a of the lower track 10 and the outer surface of the lower bent portion 30a of the upper track 30. On the inner side of the lower bent portion 10a of the lower track 10 and the outer side of the lower bent portion 30a of the upper track 30 so as to support the load applied to the upper track 30.

In addition, the upper steel ball 90b is in line contact with the inner surface of the upper bent portion 10b of the lower track 10 and the inner surface of the upper bent portion 30b of the upper track 30, and An inner surface of the upper bent portion 10b of the lower track 10 and an upper bent portion 30b of the upper track 30 to prevent the upper track 30 from escaping to the outside of the lower track 10. Is placed on the inner side of the.

In addition, in order to minimize noise and vibration generated when the upper track 30 slides along the lower track 10, the upper track 30 is in line contact with the upper and lower steel balls 90a and b. The inner and outer surfaces of the upper and lower bent portions 30a and b are configured to have a predetermined elasticity.

That is, in addition to the supporting support by the lower steel ball 90a and the prevention of external detachment by the upper steel ball 90b, the upper and lower steel balls 90a and b during the sliding movement of the upper track 30 By applying a predetermined elastic force to the upper and lower bent portions (30a, b) of the upper track 30 so as to move in a completely close state between the upper track 30 and the lower track 10, it is relieved during driving The distance can minimize noise and vibration while improving ride comfort.

In addition, a plurality of locking grooves 10c and 30c may accommodate the locking protrusions 53a formed at the ends of the locking piece 53 to be described later on the lower surfaces of the lower track 10 and the upper track 30. ) Is penetrated at regular intervals. At this time, the number of the locking grooves 30c of the upper track 30 is the same as the number of the locking protrusions 53a, and the number of the locking grooves 10c of the lower track 10 is the upper track ( It is more preferable to correspond to the sliding length of 30).

That is, since the locking groove 30c of the upper track 30 is operated in combination with the locking protrusion 53a of the locking piece 53, the locking groove 30c is formed in the same number as the locking protrusion 53a, and the position thereof is also the locking. It is preferable that it is determined based on the design fixing position of the protrusion 53a. However, the number of locking grooves 10c of the lower track 10 varies depending on the sliding length (section), and the first and end positions are also preferably corresponding to the sliding length (section).

On the other hand, the locking member 50 for locking the sliding movement of the upper track 30, as shown in Figures 3 and 4, the locking piece 53 having a large locking protrusion (53a) and the seat panel ( 70 is configured to include a rotation connecting shaft 75 coupled between the rotation shaft and the operation lever 55 having the pressing piece 55a.

Here, the locking piece 53 is pin-coupled by the coupling pin 51 on the inner surface of the seat panel 70 is rotated up and down relative to the coupling pin 51. That is, the locking piece 53 is configured to be pinned by the coupling pin 51 without being fixedly coupled to the inner surface of the seat panel 70 so that both ends may rotate up and down.

In addition, a plurality of locking protrusions 53a are integrally formed at the front end of the locking piece 53 in the vertical downward direction. Of course, the locking protrusion (53a) is made of a shape that can be fitted into the locking groove (10c, 30c) of the upper and lower tracks (10, 30) described above, by the vertical movement of the locking piece (53) The sliding motion is controlled (locked or released) by being inserted into or removed from the locking grooves 10c and 30c.

Accordingly, the locking piece 53 is an inner surface of the seat panel 70 at a position where the locking protrusion 53a of the locking piece 53 can be accommodated in the locking groove 30c of the upper track 30. It should be pinned by the coupling pin 51 on.

However, the locking protrusion 53a may be configured as three as shown in FIG. 4, but is not necessarily limited thereto. The locking protrusion 53a is accommodated in the locking grooves 10c and 30c of the upper and lower tracks 10 and 30. If the structure is made to control the number is not a problem. Of course, the number of the locking protrusion (53a) and the locking groove (30c) of the upper track 30 is preferably made the same as previously described.

In addition, the elastic spring 77 is vertically placed between the latch 71 of the seat panel 70 and the body of the locking piece 53 corresponding to the vertical downward direction of the latch 71. One end 77 is fixed to the latch 71 and the other end is fixed to the body of the locking piece 53 corresponding to the vertical downward direction of the latch 71.

That is, the elastic spring 77 is a kind of control means for the vertical movement of the locking piece 53, and the locking piece 53 is referred to the coupling pin 51 unless an external force is applied from the outside. It keeps constant without moving up and down. As a result, the rear end of the locking piece 53 and the pressing piece 55a of the operation lever 55 are kept in a predetermined distance without being in close contact with each other in the absence of external force, that is, in the locked state. In addition, the locking protrusion 53a of the locking piece 53 is unexpectedly detached from the locking grooves 10c and 30c by an impact or vibration generated during traveling, thereby preventing the possibility of unlocking.

The rotation connecting shaft 75 is laterally disposed between the seat panels 70 to connect the respective seat panels 70, but both ends thereof are coupled to the seat panel 70 without being fixed to the seat panel 70. . Here, the rotation shaft coupling of the rotary connecting shaft 75 may be made by a parallel pin 75a, as shown in Figure 3, although not shown in the figure is also made by knuckle pin (not shown) or bearing (not shown) Can be. As described above, the rotation connecting shaft 75 disposed between the seat panels 70 to form a rotation shaft coupling is configured to independently rotate on the seat panel 70. In addition, the rotation connecting shaft 75 supports the operation lever 55 to be described in detail below, and serves as a reference point for enabling the vertical movement of the operation lever 55.

As such, the reason for achieving the rotation shaft coupling without fixedly coupling the rotary connection shaft 75 is that when the operation lever 55 fixedly connected to the rotary connection shaft 75 by a method such as welding is operated up and down, This is because the operation lever 55 is not separated from the left and right or up and down, and at the same time, the load is properly distributed to the rotation shaft coupling, thereby minimizing the torsion of the locking member 50 to increase the locking effect.

And, the operation lever 55 is provided with a pressing piece (55a) that can be in close contact with the upper end of the locking piece (53) is provided at the lower end of the lower side, and the horizontally provided between the sheet panel 70 It is fixed to the upper portion of the rotary connecting shaft 75 is configured to be rotatable vertically and integrally with the rotary connecting shaft 75.

Here, the pressing piece 55a may be integrally formed at the lower end of the operating lever 55 or may be fixedly coupled to the lower end of the operating lever 55 by a joining method such as welding. It is clear that the specific shape is not a problem as long as it is not limited to FIGS. 3 and 4 and has a structure capable of closely pressing the rear end of the locking piece 53.

The upper end of the operating lever 55, that is, the upper end of the operating lever 55 facing the pressing piece 55a, protrudes from the upper end of the inner surface of the seat panel 70. It is more preferable to contact the bottom of the).

In addition, on the outer circumference of the support shaft 73 of the seat panel 70, one end is fixed to the latch 71 and the other end is provided with a torsion spring 79 for supporting the outer circumference of the front end of the operation lever 55. It is preferable to control the movement of the operation lever 55. At this time, it is more preferable that the other end position of the torsion spring 79 for holding the outer periphery of the front end of the operation lever 55 is positioned at least 20 mm past the rotation connecting shaft 75.

That is, the torsion spring 79 is a kind of control means for the vertical movement of the operation lever 55. The torsion spring 79 rotates the operation lever 55 unless the external force is applied from the handle portion 55b. Based on (75) it plays a role of keeping constant without moving up and down. As a result, the rear end of the locking piece 53 and the pressing piece 55a of the operation lever 55 are kept in a predetermined distance without being in close contact with each other in the absence of external force, that is, in the locked state.

In this way, the torsion spring 79 is placed to support the rear upper portion of the operating lever 55 fixed to the rotation connecting shaft 75, and the force is based on the rotation connecting shaft 75 The front end of the operation lever 55 is to maintain the state to be lifted to the upper portion more tightly adhered to the support shaft 73, the rear end of the locking piece 53 and the operation lever 55 The pressing pieces 55a do not come into close contact with each other in spite of shocks or vibrations while traveling, and thus maintain the predetermined separation distance.

That is, even when the vehicle is driven in an uneven section or an unpaved road by the elastic force of the elastic spring 77, the support shaft 73, and the torsion spring 79 and its structural function, the tracks 10, 30) has the effect of suppressing the noise and vibration transmitted to the maximum.

As a result, the locking projections 53a of the locking piece 53 are securely held in the locking grooves 10c and 30c until the handle 55b of the manipulation lever 55 is artificially pulled up. Will remain locked.

However, the locking member 50 is installed on both of the upper and lower tracks 10 and 30 as shown in Figure 3 can be configured to strongly control the sliding movement of the upper track 30, It is not necessarily to be installed on both sides, of course, may be installed to only one side of the upper and lower tracks 10, 30 to control the sliding movement.

If described in detail the operating state of the sliding device of the vehicle seat configured as described above are as follows.

First, when the vehicle is driven, the locking protrusion 53a of the locking piece 53 is accommodated in the locking grooves 10c and 30c of the upper and lower tracks 10 and 30 (lock state), and the upper and lower tracks 10 and The gap between the lower track 10 and the upper track 30 is completely extinguished by upper and lower steel balls 90a and b placed on the upper and lower bent portions 10a, b / 30a, and b). The riding comfort is remarkably improved by the upper and lower bent portions 30a and b having a predetermined elastic force while minimizing noise and vibration generated while driving.

And, when it is necessary to adjust the position of the seat (1) by pulling the handle portion 55b of the operating lever 55 to the upper, the operation lever 55 is fixed to the rotary connecting shaft (75). The handle portion 55b is rotated upwardly integrally with the rotary connecting shaft 75, and thus the pressing piece 55a formed at the lower end of the operating lever 55 rotates downward to the lower portion. The rear end of the locking piece 53 is pressed.

When the rear end of the locking piece 53 is supported by the pressing piece 55a of the operating lever 55 as described above, the locking protrusion of the locking piece 53 is referred to the locking pin 53 based on the coupling pin 51 by the reaction of the force. The 53a is rotated upwardly and is separated from the locking grooves 10c and 30c of the upper and lower tracks 10 and 30 to release the locked state.

On the contrary, in the case where the position of the seat 1 is to be maintained and it is to be kept locked, it is sufficient to simply release the handle of the operation lever 55 held.

That is, as described above, the elastic force of the elastic spring 77 placed between the locking piece 53 and the latch 71 of the inner side surface of the seat panel 70 and the support shaft 73 are provided. One end is fixed to the latch 71 and the other end is to prevent the elastic force of the torsion spring 79 to support the upper portion of the operation lever 55, and to prevent the front end of the operation lever 55 to rotate upwards The locking projections 53a of the locking piece 53 are again locked by the support shafts 73 and the locking grooves 53c of the upper and lower tracks 10c and 30c. It is held in a locked state.

The present invention configured as described above is to remove the space between the conventional lower track and the upper track to minimize the occurrence of noise and vibration during the driving of the vehicle as well as to adjust the position of the seat and to improve the riding comfort and control the sliding movement at the same time By distributing the load of the locking member and preventing the torsional deformation caused by it, it provides the effect of increasing the locking effect.

In addition, the present invention is not limited to those described above and illustrated in the drawings, and of course, many more modifications and variations are possible within the scope of the following claims.
