DETAILED DESCRIPTION OF THE INVENTION This invention relates to an automobile seat, particularly an automobile seat for a physically handicapped person.

Conventional automobile seats do not provide sufficient consideration for physically handicapped persons to get on and off the vehicle, and have the inconvenience of having to be helped by an attendant to get on and off the seat.

This invention was developed in view of the above-mentioned points of conventional car seats, and was improved to allow physically disabled people to get on and off the vehicle as freely as possible without the help of an attendant. The embodiment shown in FIG. 1 will be explained as follows.

FIG. 1 is an exploded perspective view of the whole, in which 1 is a base plate, 2 is a rotating frame, 3 and 4 are front support leg levers,
5 and 6 are rear support leg rods, 7 and 8 are damper mechanisms,
9 is a step, 10 is a frame for installing the step,
11 is a seat, 12 is a seat frame, and 13 and 14 are armrests.

The swing frame 2 has a substantially rectangular frame shape, and has carts 15 at the four corners of its lower surface, and has an insertion hole 17 for a swing axis 16 at one corner thereof.

The pivot shaft 16 is installed on the base plate 1 and is inserted through and coupled to the insertion hole 17 of the pivot frame 2.Thereby, the pivot frame 2 can pivot around the pivot shaft 16, and the cart 15 is attached to the base plate 1. The rotating frame 2 is supported so that the rotating frame 2 can be easily rotated by rolling on the upper surface.

The rotating frame 2 is locked by a first locking mechanism in the normal position and in the getting-on/off position. That is,
A lock pin 20 is provided on a part of the rotating frame 2 via a lock lever 19, and correspondingly, lock fittings 21 and 22 are fixed at two locations on the base plate 1.

One of the locking fittings 21 is for positioning and locking the rotating frame 2 at the normal position, and the other locking fitting 22 is for positioning the rotating frame 2 at the getting-on/off position.

The lock lever 19 is pivotally connected to a part of the rotating frame 2 via a pivot 23, and is always connected to a spring 2.
4 in the locking direction, and one end of an operating cable 25 is tied to a part of it, and the other end of this operating cable 25 is connected to one armrest 14 of the seat 11.
It is tied to an operating lever 26 provided in the.

The rotating frame 2 is locked by the locking pins 21 and 22 in the normal position and the getting-on/off position, and will not rotate accidentally unless the operating lever 26 is operated.

Furthermore, a manual safety lock 27 is further provided in a part of the swing frame 2, and a lock hole 29 corresponding to the lock pin 28 of the safety lock 27 is provided on the board 1 at the normal position of the swing frame 2, so that the lock pin 28 is double-locked. If the lock is applied, even if the operating lever 26 is operated by mistake while driving, the lock will not be released and it will be safe.

Next, the relationship between the rotating frame 2 and the seat 11 will be explained.

The front support leg rods 3 and 4 and the rear support leg rods 5 and 6 are members that serve as link elements constituting a parallelogram link mechanism A that attaches the seat 11 on the revolving frame 2 so as to be able to swing up and down approximately horizontally. First, the front support leg rods 3 and 4 are connected at their lower portions by a rotation shaft 30 so that the left and right ones rotate together in unison, and similarly, the lower portions of the rear support leg rods 5 and 6 are also connected. Rotation axis 3
1, and these rotating shafts 30 and 31 are rotatably supported through the two side plates 2a and 2b of the rotating frame 2 at the front and rear positions thereof. The upper portions of the front support leg rods 3 and 4 and the upper portions of the rear support leg rods 5 and 6 are pivotally attached to the front and rear sides of both sides of the seat frame 12, thereby forming a parallelogram link mechanism A. There is.

Therefore, the seat 11 swings up and down substantially horizontally on the rotating frame 2.

Next, a second locking mechanism for locking the seat 11 in the raised position and the lowered position will be described.

This second locking mechanism is shown attached to the front support leg rods 3, 4 in the embodiment shown in the drawings.

That is, the front support leg rods 3, 4 are formed of hollow cylinders except for the lower ends, and the operating rods 32,
33 is slidably inserted through the operating rod 32,
Attach grip handles 34 and 35 to the upper end of 33,
Lock the lower ends of the operating rods 32 and 33 with the lock pin 36,
37. Corresponding to the lock pins 36 and 37, lock holes 3 are provided in the rotating frame 2 as shown in FIG.
8,39 are provided. In this case, one operating rod 32 is used to lock the lowered position, and the other operating rod 33 is used to lock the raised position.
The swing frame 2 is provided with a lock hole 38 in the front vertical plate 2c that corresponds to the lock pin 36 when the seat 11 is in the lowered position, and the lock hole 38 corresponds to the other operation rod 32. 33
When the seat 11 is in the raised position, a lock hole 3 is formed in the horizontal surface 2d corresponding to the lock pin 37.
9 and the corresponding substrate 1 are provided with a lock cylinder 18.

As a result, when the seat 11 is in the raised position, it can be locked by pushing in one of the operating rods 33, and the lock can be released by pulling it up, and when the seat 11 is in the lowered position, it can be locked by pushing in the other operating rod 32. If you pull it out, the lock will be released.

Incidentally, the operating rods 32 and 33 may both be configured to lock the seat 11 in both the up and down positions.

Next, the damper mechanisms 7 and 8 will be explained.

The damper mechanisms 7 and 8 are located between the seat 11 and the swing frame 2, and absorb and relieve the shock when the seat 11 is lowered, and can be operated easily by assisting the return of the seat 11 to the raised position. As shown in Fig. 1, the cylinder 7
A, 8a and rods 7b, 8b are configured to be expandable and retractable, and the rod 7 is always maintained by springs (not shown) housed in cylinders 7a, 8a and high pressure gas.
b, 8b are made to protrude, and the cylinder 7
The base ends of the rods 7b and 8a are pivotally connected to the brackets 40 and 41 at the front of the swing frame 2, and the tips of the rods 7b and 8b are connected to the brackets 42 and 41 at the rear of the seat frame 12, respectively.
43.

With this configuration, the shock when the seat is lowered is absorbed and alleviated by the spring and the high-pressure gas, and when the seat returns to the raised position, it is made light by the stored elasticity of the spring and the high-pressure gas. It is something that can be done.

Next, the step 9 is fixed to the tips of two support rods 44 and 45, as shown in FIG.
It is slidably fitted into the guide tubes 46 and 47 of No. 0, and can be taken in and out as needed.

The step mounting frame 10 is fixed to the seat frame 12 on the underside of the seat 11. In addition, in FIG. 1, 48 and 49 are guide grooves provided in the guide tubes 46 and 47, and 50 and 51 are guide grooves provided in the guide tubes 46 and 47.
are guide pins provided on the support rods 44 and 45.

An example of how the seat 11 described above is installed in the vehicle body is preferably installed at the rear of the driver's seat 52, as shown in FIG. 3, but it may also be installed at the driver's seat.

In FIG. 3, the seats 11, 11 of the present invention are installed so as to be able to turn symmetrically, the normal position is the forward position shown by the solid line, and the getting on/off position is the sideways position shown by the chain line. In this case, the car body 5
3 is a 4-door type with rear seats 11, 11
There are doors on both sides of the seat, seats 11 and 11, respectively.
is rotated by 90 degrees in the direction of the arrow around the pivot shafts 16, 16, and is rotated between the normal position and the boarding and alighting position.

Next, specific operations for getting on and off the vehicle will be explained.

First, when getting on the vehicle, the user grasps the operating lever 26 of the armrest 14, removes the lock pin 20 from the lock fitting 21, and pulls the seat 11 together with the rotating frame 2 to the ingress/egress position. At this time, the seat 11 is in the state shown in FIG. Then, pull up one operating rod 33 to unlock the seat 11 in the raised position, and then push the operating rod 33 forward to open the seat 1.
1 descends as shown in FIG. 5, and at the same time the vehicle body 53
protrudes to the side, making it easier to ride. This is due to the operating characteristics of the parallelogram link mechanism A. The seat 11 can be locked in the lowered position by pushing in the other operating rod 32. In this state, a physically disabled person will ride the wheelchair, but the step 9 may get in the way when transferring from the wheelchair. In this case, the step 9 can be retracted. Then, if the physically disabled person transfers, step 9
, pull out the operating rod 32, and set seat 1.
After releasing the lock at the first lowered position, if both operating rods 32 and 33 are pulled up, the seat 11 can be easily raised to the raised position with the assistance of the damper mechanisms 7 and 8. In this state, armrest 1
4, the lock pin 20 is removed from the lock fitting 22, and the seat 11 is rotated together with the rotation frame 2 to the normal position. It is safe if the manual safety lock 27 is locked in the lock hole 29 of the board 1 in this state.

When getting off the vehicle, the above operations can be performed in the reverse order.

In the embodiment of the drawings described above, the swing frame 2 is of the pivot type, but it may be of the swing rail type, and the position and orientation of the normal position and the boarding/exiting position of the swing frame 2 relative to the vehicle body can be changed.
Furthermore, the locking mechanism is not limited to what is shown in the drawings and can be modified as appropriate.

As explained above, this invention consists of a rotating frame that is rotatably supported in the vehicle interior at a normal position and an ingress/egress position, and a front portion of a hollow cylindrical body that constitutes a pair of left and right parallel link mechanisms on the rotating frame. A seat that is mounted so as to be able to swing up and down substantially horizontally via a support leg lever and a rear support leg lever, and has armrests on both sides;
A damper mechanism is provided between the seat and the swivel frame to absorb the downward shock of the seat and assist the return of the seat to the raised position, and the swivel frame has an operating lock lever equipped with a lock pin that is constantly locked. The lock lever and the operating lever provided on the armrest of the seat are connected by an operating cable, and a locking metal fitting is provided corresponding to the locking pin at the normal position and the boarding/exiting position in the passenger compartment. A first locking mechanism has a locking pin on which a locking pin is released when the operating lever is operated; At the same time, a locking hole for locking the lowered and raised positions of the seat is formed in the rotating frame in correspondence with the locking pin of the operating rod, and the locking pin is inserted into and removed from the locking hole. Since it is equipped with a second locking mechanism that allows the seat to be inserted and latched, the seat can be lowered and protruded into the entrance of the vehicle body and pulled out using the rotating frame and the parallelogram link mechanism, making it very easy to ride. Furthermore, the damper mechanism makes it easy to return the seat to the raised position. Furthermore, although the rotating frame is locked by the first locking mechanism in the normal position and the boarding/exiting position, the lock can be easily released using an operating lever located at the hand of the occupant seated on the seat. Moreover, when the occupant is in a seated position, the seat can be raised and lowered approximately horizontally by pushing and pulling the operating rod of the second locking mechanism located near the passenger's hand. By pushing in and pulling out the seat, the seat can be locked in the lowered and raised positions and released. In this way, passengers can easily and easily operate each lock mechanism while seated in the seat, so passengers with physical disabilities can freely get on and off the vehicle on their own without the help of an attendant. This brings good news to people with physical disabilities.
