Description

Seat revolving device for automobiles {Revolution device of seat for vehicle}

The present invention relates to a seat rotating apparatus for a vehicle, and more particularly, to an improvement of a rotating apparatus that enables the seat provided in a vehicle to be rotatable in a 180 ° direction.

The seat of the car is to keep the seating position of the car occupant, and the seat of the car has a seat cushion and a seat back above the seat frame.

Below the seat frame is provided with a seat rail consisting of a lower rail fixed to the vehicle body bottom surface and an upper rail fixing the seat.

The seat rail as described above moves the front rail while the upper rail fixing the seat slides the lower rail and includes a locking system as a means for limiting such movement.

There is a rotating sheet to give a rotation function to the sheet of the general configuration as described above to enable the sheet itself to rotate in the 180 ° direction, such a rotating sheet further comprises a rotating device that can rotate by fixing the sheet above the seat rail It is a structure provided.

The seat rotating apparatus of the prior art as described above is as shown in Figure 6 and look at this as follows.

A rotary device 5 is further provided to fix the seat 4 above the seat rail 3 composed of the lower rail 1 and the upper rail 2 to rotate the seat 4 itself.

The rotary device 5 is provided with a lower plate 6 fixed to the upper rail 2 of the seat rail 3 and an upper plate 7 fixed to the lower plate 6, and the upper and lower plates 7 and 6. ) Is provided with a rotating plate 8 which is interposed between the phases to fix the sheet 4.

The first groove 9 of a circular shape formed by bending the lower plate 6 and the rotating plate 8 and the second groove 10 formed by bending the upper plate 7 and the rotating plate 8 are slipped. The rotating means 12 is comprised by inserting the ball 11 for ease.

The upper plate 7 and the rotating plate 8 is a configuration having a fork-type stopper that can control the rotation state of the rotating means 12.

In the prior art as described above, since the rotating means is composed of a plurality of rows, and in particular in a state of interposing a large number of steel balls, there is a problem that a significant frictional force is generated and the operating force is reduced.

In particular, since the rotating means are formed on the upper plate, the rotating plate, and the lower plate and the rotating plate, respectively, to have a dual configuration, the rotating device is complicated, which causes considerable difficulties in manufacturing, resulting in excessive production costs. It is happening.

Accordingly, the present invention is to solve the problems described above to simplify the rotating means constituting the sheet rotating device to the upper plate and the lower plate characterized in that it can contribute to cost reduction by improving productivity and reducing the number of parts involved do.

In particular, the purpose of the present invention is to reduce frictional forces generated in the course of the sheet operation, to ensure a smooth operating force, thereby contributing to the convenience of the users, and to improving the quality of the sheet rotating apparatus.

Fig. 4 is a plan view showing the seat revolving device for automobiles to which the technology is applied. Fig. 4 is a cross-sectional view taken along the line A-A of the car seat revolving device shown in Fig. 3, and Fig. 5 is a revolving seat for the car shown in Fig. 3. The apparatus is described together as a cross-sectional view showing another example taken along the A-A line.

Conventional seat 30 is provided in the vehicle 31 is provided so that it is difficult to change the direction, but the seat 30 is easy to ride by providing a rotation device 40 so that the direction is free to change in the 180 ° direction It is to be able to pursue convenience.

In the present invention, by improving the rotation means 50 provided in the rotating device 40 is characterized in that it can contribute to the improvement of productivity while having a more easily operability.

Rotating means 50 to which the technique of the present invention is applied provides an ease of rotation between the upper plate 51 fixing the sheet 30 and the lower plate 52 coupled to the upper plate 51 and fixed to the seat rail. It is comprised through the bearing 55.

The bearing 55 is composed of an upper bearing 57 fixed to the upper plate 51 by fixing means 56 such as bolts or rivets, and a lower bearing 58 fixed to the lower plate 52 by fixing means 56. do.

The upper and lower bearings 57 and 58 are integrally formed from a flat flange 60 and the flange 60 for fixing the upper and lower plates 51 and 52 to protrude downward and upward. 61).

A bushing 66 is interposed between the upper and lower bearings 57 and 58 so as to facilitate the coupling of the upper and lower plates 51 and 52 between the holding tubes 61. After finishing with a rocker plate (67).

Of course, the space 65 formed between the upper and lower bearings 57 and 58 may be interposed with friction force reducing means such as a ball 68 or a roller 69 for reducing friction and improving rotational force. It will be apparent that a conventional stopper 100 is provided between the upper portion of the 51 and the lower plate 52 to control the rotation.

The present invention as described above;

Since the sheet 30 is not moved in the initial state by the conventional stopper 100 provided between the upper plate 51 and the lower plate 52, the sheet 30 is in a state in which rotation is impossible.

In this state, when the sheet 30 is to be rotated, the sheet 30 can be easily rotated by 180 ° by releasing the stopper 100.

When the seat 30 rotates as described above, the seat fixed to the bottom surface of the vehicle body by a bearing 55 composed of an upper bearing 57 and a lower bearing 58 fixed to the upper and lower plates 51 and 52. The upper plate 51 which fixed the sheet | seat 30 with respect to the lower board 52 couple | bonded with a rail becomes possible by being able to rotate.

In particular, in the space 65 between the upper and lower bearings 57 and 58 interposed between the upper and lower plates 51 and 52, the friction force may be reduced through the bushing 66 to allow easier rotation. have.

In addition, the seat 30 is more easily provided by interposing the friction force reducing means such as the ball 68 and the bearing 69 in place of the bushing 66 interposed in the space 65 between the upper and lower bearings 57 and 58. Will be able to rotate.

The present invention as described above can be configured simply by the upper and lower plates and the bearings interposed therebetween the rotating means of the seat rotating device to contribute to the improvement of productivity and cost reduction, as well as to reduce the friction force generated during the operation smooth It is possible to obtain a variety of effects, such as to contribute to the improvement of users' convenience by securing the operating force.
