Description

[Detailed Description of the Invention] The present invention relates to the improvement of automobile seats, particularly front seats, in which the seat cushion faces the door opening side and can be tilted forward and downward when a passenger gets in and out of the vehicle. The purpose is to improve the ease of getting on and off the vehicle.

Conventional automobile seats, especially front seats in passenger cars, are configured to adjust the seat back and forth using a seat slide device, and adjust the inclination angle of the seat back using a reclining device to improve riding comfort. However, the ease of getting on and off the vehicle has not been considered at all, and passengers are required to move their trunks to get on and off the vehicle.As a result, their clothes get tangled and they have to make extra movements, making it difficult to get on and off the vehicle. It was extremely bad.

By adopting the configuration described in the claims of the utility model registration, the present invention allows a conventional automobile seat equipped with a seat sliding device and a reclining device to also have a function that can further improve the ease of getting on and off the seat. .

The configuration of the illustrated example will be explained below.

FIGS. 1 to 5 show an embodiment of a passenger seat for a passenger car, in which a seat cushion 1 is located between a pair of left and right seat slide upper rails 2 and 3 in a slide device for adjusting the position of the seat cushion 1 in the longitudinal direction. , a rotating base 4 is fixed.

A flat truncated cone-shaped pedestal part 5 is provided on the rotating base 4 at a position eccentric from the center line 0-0 toward the outside of the vehicle body as indicated by an arrow A, and its upper surface 6
is inclined by an angle θ so as to form a downward slope toward the outside of the vehicle body as indicated by the arrow A.

On the other hand, a turntable 8 is fixed to the lower surface of the seat cushion frame 7, and the turntable 8 has a seating section 9 that is fitted closely onto the upper surface 6 of the pedestal section 5 on its lower surface. It is recessed in.

The seating section 9 of the turntable 8 described above is firmly supported by a retainer 11 and a presser disk 12, which are fixed to the pedestal section 5 with bolts 10, so that it will not come off even if it rotates.

With the above structure, the seat cushion 1 is slidably displaced back and forth with respect to the seat slide upper rails 2, 3 integrally with the rails 2, 3, and at the same time, the pedestal section 5 It is mounted so as to be rotatable in the direction shown by arrow B in FIGS. 1, 3, and 5 about the center of rotation.

Since the upper surface 6 of the pedestal portion 5 is inclined at an angle θ so as to form a downward slope toward the outside of the vehicle body as indicated by arrow A, when the front portion of the seat cushion faces toward the outside of the vehicle body, the seat cushion The seat surface of the seat 1 is inclined downwardly toward the outside of the vehicle body.

By the way, since it is necessary to fix the position of the seat cushion 1 when sitting other than when getting on and off, in the illustrated embodiment, the seat cushion frame 7 is provided with a lock having the structure shown in FIGS. 6 and 7. The device 13 is attached to the pedestal section 5 and the seating section 9, on the other hand, a first
A lock cutout 15 is provided as shown in FIGS. 3 and 5.

The locking device 13 described above includes an operating shaft 19 which is rotatably supported on the seat cushion frame 7 by supports 16 and 17, and to which a rotating force is constantly applied in the direction of arrow C by a torsion spring 18; 19; an L-shaped locking claw 20 fixed to the end;
An operating rod 23 that is perpendicular to the operating shaft 19 and is slidably supported on the seat cushion frame 7 by supports 21 and 22, and a link that connects the tip of the operating rod 23 and the intermediate portion of the locking pawl 20. 24, and the tip 25 of the locking pawl 20 is rotated by the rotational force in the direction of arrow C, which is constantly applied to the operating shaft 19 by the elasticity of the torsion spring 18.
By fitting into the lock notch 15 of the inner cavity 14 of the base part 5 and the seat part 9, the seat cushion 1
is always locked in its normal position and maintained at that position.

The handle portion 26 at one end of the aforementioned operating shaft 19 is
Located in front of passenger seat seat cushion 1,
A knob portion 27 at one end of the operating rod 23 is arranged on the side surface of the passenger seat seat cushion 1 on the driver's seat side.

To release the lock, the passenger sitting in the passenger seat only has to rotate the handle portion 26 of the actuating shaft 19 in the direction opposite to arrow C against the elasticity of the torsion spring 18. Locking claw 2
The tip 25 of the seat cushion 1 escapes from the lock notch 15, and the seat cushion 1 becomes able to rotate freely with respect to the base portion 5.

To unlock the device, the occupant in the driver's seat must hold the knob 27 of the operating rod 23 and press the lever 2.
3 in the direction of pulling out, the locking pawl 20 and the operating shaft 19 are rotated in the opposite direction to the arrow C through the link 24, and the lock is released in the same manner as described above. be.

After the lock is released as described above, the seat cushion 1 is moved to the seating portion 9 of the turntable 8.
However, since the seat can be rotated on the pedestal 5 of the rotating base 4, the seated occupant only has to slightly twist his or her trunk toward the door, and the seat can be rotated on the slanted top surface 6 of the pedestal 5. The vehicle is guided by the vehicle and rotates toward the opening of the door, and slopes downward toward the outside of the vehicle, making it easier to exit the vehicle.

Furthermore, since the pedestal portion 5 is provided at a position eccentric to the outside of the vehicle body from the center line 0-0 of the rotating base 4, when the seat cushion 1 is rotated, the outermost end of the seat back 28 is located at the position shown in FIG. The seat back 2 will move according to the rotation locus indicated by the reference numeral 29, and the seat back 2 will move when the pedestal portion 5 is provided on the center line 0-0.
Since it rotates at a position closer to the outside of the vehicle body than the rotation locus 30 at the outermost end of No. 8, interference with the driver's seat is prevented.

The automobile seat according to the present invention has the structure and function described below, and the upper surface of the pedestal part of the rotating base is inclined downwardly toward the outside of the vehicle body, and the seat cushion is placed on this upper surface. The seat of the turntable is rotatably supported, so when getting off the vehicle, the seated person only has to apply a small amount of initial force to the seat cushion, and the seat cushion moves toward the door opening side. Since it rotates and tilts downward, it prevents clothes from getting tangled.
You can easily get out of the car without having to make any major movements of your trunk, and when you get in the car, you can rotate the seat cushion toward the door opening and sit down from outside the car. All that is required is to rotate the seat cushion to the normal position, and this has the effect of significantly improving the ease of getting in and out of the automobile.

In addition, the rotating base is fixed between the pair of left and right seat slide top rails, and the turntable on the seat cushion frame side is supported on this rotating base. There is also the advantage that the reclining function is not compromised in the slightest.
