Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a walk-in device for reclining an automobile seat, which is used when getting on and off the rear seat side of an automobile.

(Prior Art) A front seat in an automobile is usually provided with a reclining device that can adjust the seat back to a desired inclination angle according to the preference of the occupant.

On the other hand, when a front seat and a rear seat are provided on the vehicle interior floor, a walk-in device may be provided to facilitate getting on and off the rear seat side.

Here, the walk-in device is a device that makes it possible to expand the space between the front and rear seats when getting on and off, and usually the seat back of the front seat can be rotated forward and The front seats can be moved forward in this condition.

In addition, in the above configuration, if the front seat is moved forward when getting on or off the rear seat side, the safety standards for seat belts on this seat may no longer be met. A locking device has been proposed that holds the seat bag in a forward-rotated position so that the user cannot sit on the seat (for example, Japanese Utility Model Application Publication No. 58-70929).

(Problems to be Solved by the Invention) Conventionally, a reclining device and a walk-in device as described above are individually provided for one front seat, resulting in a complicated configuration. There is.

(Purpose of the invention) This invention was made with attention to the above-mentioned circumstances, and the purpose of this invention is to easily configure a walk-in device using a reclining device for an automobile seat.

(Structure of the invention) In order to achieve the above object, this invention is characterized by the engagement between a gear provided on the seat back side and an engaging tooth formed on the operating lever on the seat cushion side. The seat bag can be held in a desired inclined position, and the engagement between the gear and the engagement teeth is maintained in a state where the seat bag is rotated toward the seat cushion during walk-in.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

Reference numeral 1 denotes an automobile, and a front seat 3 and a rear seat 4 are provided on a cabin floor 2 of the automobile 1.
A door opening 5 is formed on the side of the front seat 3.

The front seat 3 will be explained below.

A seat cushion 6 is mounted on the vehicle interior floor 2 and is movable back and forth via a slide rail (not shown).
is supported. Further, a seat bag 8 is pivotally supported at the rear end of the seat cushion 6 via a pivot means 7 so as to be rotatable back and forth. The seat bag 8 includes a bracket plate 9 attached to the rear side surface of the seat cushion 6, a lower arm 10 attached to the lower side surface of the seat bag 8, and a pivot that rotatably supports the bracket plate 9 and the lower arm 10. It is composed of a support shaft 11.

Next, a reclining device that can adjust the seat back 8 to a desired inclination angle will be described.

A sector-shaped gear 13 is attached to the lower arm 10 above the center of rotation of the seat bag 8.

On the other hand, reference numeral 15 denotes an operating lever, and this operating lever 15 is composed of a first operating lever 14 and a second operating lever 19, which are rotatably supported on the bracket plate 9, respectively. An engagement tooth 17 is provided at the rotation end of the first operation lever 14 and engages with the gear 13 in a detachable manner as the first operation lever 14 rotates.
is formed. In addition, the second operating lever 1
One end of the rotating end of the lever 9 is in contact with the rotating end of the first operating lever 14 .

A spring 18 is installed between the second operating lever 19 and the bracket plate 9, and this spring 18 causes one rotating end of the second operating lever 19 to press against the first operating lever 14 and engage the gear 13. The second operating lever 19 is urged so that the engagement teeth 17 are engaged.

Normally, the second operating lever 19 is biased by the spring 18, so that the engagement tooth 17 engages with the gear 13, thereby preventing the seat back 8 from freely rotating (see Fig. 2). (solid line shown). Also,
When adjusting the seat back 8 to a desired inclination angle according to the preference of the seated person, the second operation lever 19 is rotated against the elastic force of the spring 18.
Accordingly, if the first operating lever 14 is rotated to disengage the engagement teeth 17 from the gear 13,
Free rotation of the seat back 8 is allowed (second
(Illustrated with chain double-dashed lines in the figure). Then, when the operation on the second operating lever 19 is released at the desired inclination angle of the seat bag 8, the engaging tooth 17 engages with the gear 13 again by the biasing force of the spring 18, and the seat bag 8 is held at that angle. .

Next, a walk-in device that can widen the distance between the front and rear seats 3 and 4 when getting on and off the rear seat 4 side will be described.

A push-pull cable 21 is installed between the vehicle interior floor 2 and the front seat 3. That is, the outer cable 22 is supported by the bracket plate 9, and the inner cable 23 is slidably inserted into the outer cable 22. The rear end of this inner cable 23 is connected to the vehicle interior floor 2 by a connector 24. The front end of the inner cable 23 is slidably fitted into a locking notch 26 formed in the second operation lever 19, and the end of the inner cable 23 is fitted with a locking notch 26 that engages with the locking notch 26. A stop head 27 is attached.

As shown by the solid line in FIG. 1, in the normal state in which the front seat 3 moves backward,
As shown in FIG. 2, the locking notch 26 and the locking head 2
7 is disengaged, so that the seat back 8 can be tilted to a desired angle by operating the second operating lever 19.

On the other hand, when walking in, the seat back 8 is rotated forward as shown by the dashed line in FIG. 1, and then the front seat 3 is moved forward as shown by the dashed double dot line in FIG. , the space between the front and rear seats 3 and 4 is expanded,
Getting on and off the rear seat 4 can be done smoothly. In this case, as shown in FIG. 3, the locking head 27 engages with the locking notch 26 while the engaging tooth 17 is engaged with the gear 13, that is, the inner cable 23 is tensioned. occurs, and the rotation of the second operating lever 19 is blocked, and accordingly, the rotation of the first operating lever 14 is also blocked. As a result, the seat back 8 is kept rotated forward, making it impossible for the user to sit on the front seat 3.

(Effects of the invention) According to this invention, the seat back can be held in a desired tilted posture through engagement between the gear provided on the seat back side and the engagement teeth formed on the operating lever on the seat cushion side. In some cases, during walk-in, to prevent sitting on the seat,
Since the engagement between the gear and the engagement teeth is maintained when the seat back is rotated toward the seat cushion, the gear and the operating lever that make up the seat reclining device, as well as the operating lever, are A walk-in device was obtained by making use of the engaging teeth and the like and simply adding a simple structure such as a cable.
Therefore, this walk-in device can be easily configured.
