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. The seat of the car has a seat cushion and a seat back above the seat frame, and a lower rail and a seat fixed to the bottom of the car body below the seat frame. It is provided with a seat rail consisting of an upper rail for fixing the.

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 also a rotating sheet to give a rotation function to the sheet of the general configuration as described above to be able to rotate the sheet itself 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 8 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.

In the present invention, to solve the problems as described above to simplify the configuration of the rotating means of the seat rotating device to contribute to the improvement of productivity, as well as to reduce the friction force generated during the operation to ensure a smooth operating force In order to contribute to the user's convenience improvement and to improve the quality of the seat rotating device.

Fig. 4 is a plan view showing a partial fracture of the seat revolving device for automobiles to which the technology is applied. Excerpt sectional view taken along line B of the sheet rotating apparatus, FIG. 6 is an excerpt sectional view taken along line C of the automobile seat rotating apparatus shown in FIG. 3, FIG. 7 is line D of the automobile seat rotating apparatus shown in FIG. It will be described together as a cross-sectional view taken along the following.

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.

The rotary device 40 provided in the seat 30 is provided by fixing the seat 30 on the upper seat rail consisting of a lower rail and an upper rail, the lower plate 45 and the lower plate is fixed to the upper rail An upper plate 46 fixed with the 45 is provided.

The upper and lower plates 45 and 46 are interposed between upper and lower rotating plates 47 for fixing the sheet 30, and upper and lower plates 45 and 46 and upper and lower rotating plates 47 are provided with rotating means 50. The upper plate 46 and the rotating plate 47 are configured to have a conventional stopper capable of controlling the rotation state of the rotating means 50.

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 is arranged on the bent portion 51 formed on the inner surface of the rotating plate 47 in order to have a plurality of protrusions 52, 53, 54 in a regular arrangement. It is formed to protrude.

Upper and lower ends of the upper and lower plates 45 and 46 coupled to each other on the upper and lower sides of the rotating plate 47 to form protrusions 52, 53, and 54 formed at the bent parts 51 to accommodate the upper and lower ends. Lower bends 55 and 56 are formed.

The upper and lower bent portions 55 and 56 fix the bushes 59 and 60 having recesses 57 and 58 to accommodate the projections 52, 53 and 54 of the rotating plate 47 to rotate the rotating plate 47. ) It is configured to enable easy rotation while reducing frictional force generated during rotation.

The present invention as described above;

Since the sheet 30 is not moved by the conventional stopper provided between the upper plate 46 and the rotating plate 47 in the initial state, 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.

When the seat 30 rotates as described above, the upper and lower plates coupled to the seat rail fixed to the bottom surface of the vehicle body by the rotation means 50 provided between the upper and lower plates 45 and 46 and the upper and lower rotary plates 47. It becomes possible by the rotation plate 47 which fixed the sheet | seat 30 with respect to 45 and 46 which can rotate.

Particularly, the rotating means 50 accommodates the protrusions 52, 53, 54 and the protrusions 52, 53, 54 formed on the bent portion 51 of the rotating plate 47. The friction force is reduced by the bushes 59 and 60 fixed to the upper and lower bent portions 55 and 56 formed at the outer end portions of the 46, so as to allow easier rotation.

The present invention is the upper and lower plates to accommodate the projections (52, 53, 54) and the projections (52, 53, 54) to form the rotating means 50 to protrude upward and downward of the rotating plate 47 The bush (59, 60) fixed to the (45, 46) can be easily provided by reducing the frictional force due to the simple operation.

The present invention as described above can simplify the configuration of the rotation means of the seat rotating device to contribute to the improvement of productivity, as well as to reduce the frictional force generated during the operation to ensure a smooth operating force to contribute to the user's convenience improvement And various effects can be obtained, such as to contribute to the improvement of the quality of the sheet rotating apparatus.
