Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an automobile seat in which a side wall portion for suppressing lateral movement of a seated person is provided on the side of the cushion.

``Prior Art'' In automobile seats, in which side walls are provided on the sides of the cushion to suppress the lateral movement of the seated occupant, the side walls obstruct getting on and off, so improvements have been made to ensure ease of getting on and off. It has been done.

Examples of conventional automobile seats include those shown in FIGS. 6 and 7, for example.

That is, side walls 3 and 4 are provided across the front and rear sides of the cushion 2 of the seat 1 to suppress the lateral movement of the seated person, and the outer side wall 3 is designed to fall outward when getting on and off the seat. It is something that exists.

``Problems that the invention seeks to solve'' However, with such conventional car seats, since the side wall portion 3 is simply folded down, it is difficult to fold it down sufficiently due to space constraints, and it is difficult to achieve the intended purpose. The raising and lowering operation is also troublesome, and furthermore, when the side wall 3 is raised, there is a problem in that clothes are caught between the main body of the cushion 2 and the side wall 3, making it uncomfortable.

Furthermore, as disclosed in Japanese Utility Model Application Publication No. 59-94931, there is a cushion in which the entire cushion is tilted sideways, but since the cushion is originally a place that receives the weight, it is difficult to force the weight to shift when getting on and off. The problem was that it was forced to do this and had poor operability.

The present invention was developed by focusing on these conventional problems, and it is easy to operate, the side wall part escapes enough so that it does not get in the way of the seated person when getting on and off, and there is no chance of clothes getting caught. The purpose of the present invention is to provide an automobile seat that has the following features.

``Means for Solving the Problems'' The gist of the present invention for achieving the above purpose is to provide an automobile seat in which a side wall portion for suppressing lateral movement of a seated person is provided on the side of the cushion. , the cushion is divided into front and rear parts, and the lower part of the rear part is pivoted to the vehicle body side by a pivot in the longitudinal direction of the vehicle body, and supported so as to be tiltable so that the seat surface faces the side entrance/exit door. The present invention resides in an automobile seat characterized by comprising a locking mechanism that holds the front portion substantially horizontally.

``Function'' When seated, the lock mechanism holds the front part of the cushion almost horizontally so that it continues to the rear part, and the seated person can sit stably on the seat because lateral movement is suppressed by the side walls. be able to.

When the locking mechanism is released, the front part of the cushion is tilted so that the seat faces outward toward the side entrance, the outer side wall part sinks, and the inner part of the front part of the cushion becomes floating, and the rear A seated person who has put his/her weight on the vehicle can smoothly step over the outer side wall and exit the vehicle by simply lifting his or her feet slightly.

When riding, place your hips on the back of the cushion and place your feet, which are outside the car, on the front of the cushion. Due to your weight, the inside of the front of the cushion sinks and becomes almost horizontal, and the locking mechanism works and locks itself. It is something that

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 to 5 show an embodiment of the present invention.

The seat 10 is of a so-called bucket type, and as can be seen in FIGS. 4 and 5, horizontal restraining parts 12, 12 are provided on both sides of the seat back 11, and the cushion 20 is divided into a rear part 30 and a front part 40. Side wall portions 21 and 22 are provided on both sides of the cushion 20 across the rear portion 30 and the front portion 40 to suppress lateral movement of a seated person. The side walls 21 and 22 are fixed to both sides of the front part 40, and if the seat 10 is for a driver's seat, the side wall 21 is on the outside where the passenger entrance is located, and the side wall 22 is on the inside of the vehicle.

As can be seen in FIG. 1, the cushion 20 is installed on a base 23, and the base 23
3 and 13 to be installed on the vehicle body.

At the rear of the base 23 is a rear part 30 of the cushion 20.
is fixed, and a cushion 20 is fixed to the front part of the base 23.
The front part 40 of is pivoted. Rear part 30 that does not move
A seat back 11 is attached to the seat via a reclining mechanism 14.

A pivot bracket 24 is provided at the front and back of the front part of the base 23,
25 is fixed, and mounting brackets 41 and 42 are fixedly installed at the lower part of the front part 40 of the cushion 20.
A pivot rod 43 in the front and rear direction is inserted through the rod 42 and is prevented from coming off with a nut 44. axis rod 43
A spring 45 is wound around the front portion 40 to bias the front portion 40 in an outwardly inclined direction.

A locking mechanism is provided corresponding to the end portion of the front portion 40 of the cushion 20 on the passenger compartment side.

The locking mechanism consists of a latch member 46 pivotally attached to the end of the front portion 40 of the cushion 20 and a striker 47 fixed to the base 23.
6 has a hook portion 46a at the tip and is provided with an operating knob 46b, which is biased in the locking direction by a spring 46c. The top of the hook portion 46a forms an abutting guide surface on which the latch member 46 rotates in the release direction when the striker 47 abuts.

Next, the action will be explained.

When seated, the front part 40 of the cushion 20
As shown in the figure and FIG. 4, it is held substantially horizontally and is continuous with the rear portion 30. Seated people sit on side wall 2
1 and 22 are seated stably with lateral movement suppressed.

When getting off the vehicle, hold the operating knob 46b of the latch member 46 forming the lock mechanism and rotate it in the release direction to release the striker 47.
When the weight is placed on the rear part 30 and the foot is slightly lifted with the foot unlatched, the front part 40 of the cushion 20 pivots around the pivot rod 43 due to the biasing force of the spring 45, as shown in FIGS. 2 and 5. The seat is tilted so that the seat faces the outside entrance. The side wall portion 21 sinks and escapes, and the inside of the front portion 40 appears floating.

Therefore, the user rotates his/her body around the waist above the rear part 30 and puts his or her feet out of the vehicle. Since the side wall portion 21 is removed, there is nothing to get in the way, and the foot can be moved smoothly. Rear 30 when your feet touch the ground
I can get out of the car by lifting my hips up.

When getting on the vehicle, first press the rear part 3 of the cushion 20.
Sit on 0 and rest your weight on it. Next, move your foot over the escaped side wall 21 and into the car, and place your foot on the inside of the passenger compartment of the front part 40 of the cushion 20. Due to the weight of this foot, the front part 40 of the cushion 20 springs 45. rotates horizontally against the urging force of
When the striker 47 comes into contact with the top of the hook portion 46a of the latch member 46, the latch member 46 slides in the releasing direction, and when the striker 47 is fitted into the latch member 46, it returns and latches.

As a result, the front portion 40 of the cushion 20 is placed in the substantially horizontal state shown in FIGS. 3 and 4, allowing the seated person to sit stably.

``Effect of the invention'' According to the automobile seat of the invention, the cushion is divided into the front and rear parts, and only the front part tilts outward, so that the weight of the seated person can shift smoothly and extremely. The vehicle seat is easy to ascend and descend, is easy to operate according to the movement of getting on and off, does not trap clothes, and has extremely improved ease of getting on and off.
