Description

The present invention relates to an auxiliary seat provided in a gap between a vehicle seat and an entrance / exit to assist passengers in getting on and off.

Conventionally, ordinary automobiles have a specification in which an occupant bends down and sits on a vehicle seat when getting on and off the vehicle. However, for a person with a disability or a weak leg, such a specification puts a heavy burden on the body and makes it difficult to get on and off the vehicle smoothly. Under such circumstances, an auxiliary sheet having a simple structure and being easily attached is desired.

In Reference 1, an auxiliary seat is provided on the outside of the vehicle seat in the vehicle width direction, and when getting on and off the vehicle, the occupant himself inverts the auxiliary seat toward the door side, so that the auxiliary seat is deployed outside the vehicle. The technology is described. According to this technology, when getting on and off the vehicle, the auxiliary seat is provided so as to protrude to the outside of the vehicle, so that getting on and off the vehicle becomes smooth and there is no need to bend down to get on and off. Therefore, a person with a disability or a person with a weak leg can comfortably get on and off the vehicle.

However, in Cited Document 1, it is troublesome for the occupant to knock down or raise the auxiliary seat by himself / herself each time he / she gets on / off the vehicle. In addition, when the occupant is using a wheelchair, it is necessary to move the wheelchair in and out between the outside of the vehicle and the rear seats after getting on and before getting off. When the wheelchair is taken in and out after getting in or out of the vehicle, if there is an auxiliary seat folded next to the vehicle seat, it may hinder the putting in and out of the wheelchair. In addition, it was inconvenient to have the auxiliary seat in the unfolded state because the wheelchair could not be unfolded or folded right next to the seat for the vehicle in which it was seated.

Further, in order to realize smooth getting on and off of a passenger car, there is a technique of rotating the vehicle seat itself to the outside in the vehicle width direction and sliding it to the outside of the vehicle, but the configuration is complicated and the installation cost is high. In addition, since the vehicle seat itself is slid to the outside of the vehicle, it is necessary to secure a certain amount of space for getting on and off the vehicle when getting on and off.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an auxiliary seat which can smoothly get on and off a passenger car and can be easily installed when getting on and off a passenger car.

(1) In order to achieve the above object, the present invention has taken the following measures. That is, the auxiliary seat of the present invention is an auxiliary seat provided in the gap between the vehicle seat and the entrance / exit to assist the occupants in getting on / off, and has a predetermined width in the width direction of the vehicle. A strut whose one end is fixed to the vehicle body in the gap between the seat and the entrance / exit, and a strut provided at the other end of the strut, which protrudes in the front-rear direction of the vehicle, and the length in the vertical direction is the length in the horizontal direction. A seating unit that has a larger set of protrusions and at least a long seating surface and is supported by the columns so that it is approximately flush with the seating surface of the vehicle seat during use, as opposed to the long seating surface. The seating surface unit is provided on the side surface so as to be parallel to the long seating surface and parallel to each other and facing each other, and is closed by the first closing surface of the first end portion, while the first closing surface is closed. At the second end, which is the end opposite to the end, the second end is bent at a right angle so as to project in the direction opposite to the long seat surface and is closed at the second closing surface, and the second closing surface and the said. The seat is provided with a set of guide grooves in which the distance from the surface facing the second closed surface is substantially the same as the length of the protrusion in the vertical direction and the protrusions are slidably engaged with each other. The surface unit is supported by the support column by the long seat surface being located on the vehicle seat side of the support column and the first closing surface of each guide groove and the protrusions in contact with each other in the stored state. During the transition from the stored state to the used state, the protrusions are slid in the guide grooves, and the sliding direction of the protrusions is perpendicular to the guide grooves at the second end of the guide grooves. At a position where the long seat surface is substantially perpendicular to the vertical direction, the lower end portion of each protrusion in the vertical direction and the second closed surface of each guide groove come into contact with each other, and the other end of the support column. It is characterized in that it is supported by the support column by coming into contact with the support.

As described above, the auxiliary seat of the present invention is an auxiliary seat provided in the gap between the vehicle seat and the entrance / exit to assist the passengers in getting on / off, and has a predetermined width in the width direction of the vehicle. A strut whose one end is fixed to the vehicle body in the gap between the vehicle seat and the entrance / exit, and a strut provided at the other end of the strut, which protrude in the front-rear direction of the vehicle, and the length in the vertical direction is longer than the length in the horizontal direction. On a seating unit that has a large set of protrusions and at least a long seating surface and is supported by struts so that it is approximately flush with the seating surface of the vehicle seat during use, and on the surface opposite the long seating surface. The seat unit is provided on the seat unit so as to be parallel to the long seat surface and parallel to each other and face each other, and is closed by the first closing surface of the first end, while the end opposite to the first end. At the second end, which is bent at a right angle so as to project in the direction opposite to the long seat surface, the second closed surface is closed by the second closed surface, and the second closed surface and the surface facing the second closed surface The distance is approximately the same as the vertical length of the protrusions, and each protrusion is provided with a set of guide grooves that are slidably engaged with each other. Therefore, the seat surface unit is in the retracted state, and the long seat surface is the support column. It is located on the vehicle seat side of the above, and is supported by the support column by abutting the first closing surface of each guide groove with each protrusion. As a result, it can be stored compactly even in a narrow space. Further, in the seating surface unit, each protrusion is slid in each guide groove during the transition from the stored state to the used state, and the sliding direction of each protrusion with respect to each guide groove is set at the second end of each guide groove. Change to a right angle, and at a position where the long seat surface is approximately orthogonal to the vertical direction, the lower end of each protrusion in the vertical direction and the second closed surface of each guide groove should come into contact with each other and the other end of the support column. Since it is supported by the support column, the contact point with the other end of the support column is used as a fulcrum, and the second closed surface that contacts the lower end portion in the vertical direction of each protrusion is used as the action point against the load applied to the seat surface unit. As a result, the balance of forces in the vertical direction is established, so it is possible to support the occupant with high strength. Further, since the long seat surface of the seat surface unit is provided outside the vehicle on the entrance / exit side when the auxiliary seat is used, that is, when getting on / off the vehicle, the occupant can smoothly get on / off the vehicle. In addition, since the long seat surface can be installed in the horizontal direction by sliding each protrusion in each guide groove by the user himself, a simple structure is adopted without the need for a power source such as an electric motor or a hydraulic actuator. It is possible to reduce the cost of installation and the like.

(2) Further, in the auxiliary sheet of the present invention, the width of each of the guide grooves is substantially the same as the length of each of the protrusions in the horizontal direction.

As described above, since the width of each guide groove is substantially the same as the horizontal length of each of the protrusions, the vehicle at the upper end of each protrusion of the guide groove is subjected to a load applied to the seat surface unit when the auxiliary seat is used. Since the horizontal force balance is established with the point of contact with the seat side as the fulcrum and the point of contact with the entrance / exit side of the lower end of each protrusion in the vertical direction in the vertical direction as the point of action, the vertical force in the above (1) is established. In addition to the directional balancing structure, it is possible to support the occupant with even higher strength.

(3) Further, in the auxiliary seat of the present invention, the seat surface unit has a short seat surface orthogonal to the long seat surface, and in the stored state, the short seat surface is substantially orthogonal to the vertical direction, while in use. The short seat surface is parallel to the vertical direction.

As described above, the seating surface unit has a short seating surface orthogonal to the long seating surface, and the short seating surface is substantially orthogonal to the vertical direction in the stowed state. Therefore, the seating surface unit does not interfere with the driving operation of the occupant during the stowed state. On the other hand, in the used state, the short seat surface is parallel to the vertical direction, and the long seat surface having a larger area than the short seat surface can be used as the upper surface, so that the user can easily sit down and get on and off.

According to the present invention, it is possible to provide an auxiliary seat capable of smoothly getting on and off the passenger car and easily installing the auxiliary seat when getting on and off the passenger car.

As shown in FIGS. 1A to 1C, FIGS. 2A to 2C, and FIGS. 3A to 3C, the auxiliary seat 100 according to the present embodiment is provided in the gap between the vehicle seat and the entrance / exit, and is provided in the width direction of the vehicle. A seat surface having a support column 11 having a predetermined width, a set of protrusions 13 (13a, 13b) provided at the ends of the support columns 11, and a long seat surface 21b and a short seat surface 21a orthogonal to the long seat surface 21b. The unit 21 is provided with a set of guide grooves 31 (31a, 31b) provided in the seat surface unit 21 so as to be parallel to each other and face each other with the long seat surface 21b. One end of the support column 11 is fixed to the flat plate 61. The flat plate 61 is fixed to the vehicle body.

The protrusion 13 has a structure in which the auxiliary seat 100 protrudes in the front-rear direction of the vehicle when the auxiliary seat 100 is provided in the gap between the vehicle seat and the entrance / exit. The set of protrusions 13 (13a, 13b) provided at the ends of the columns 11 has a cross section in which the length in the vertical direction is larger than the length in the horizontal direction. In the present specification, the protrusions 13 (13a, 13b) are formed by juxtaposing the two protrusions (13-1a, 13-1b, 13-2a, 13-2b) having a circular cross-sectional shape in the vertical direction. Although the vertical length of 13 is made larger than the horizontal length, the present invention is not limited to this.

The guide groove 31 is bent at a right angle to the first end portion 41 (41a, 41b) that is closed by the first closing surface 43 (43a, 43b) so as to project in the direction opposite to the long seat surface 21b, and the second A second end portion 51 (51a, 51b) that is closed by the closing surface 53 (53a, 53b) of the above is provided. The second end 51 (51a, 51b) is located at the end opposite to the first end 41 (41a, 41b) and is bent at a right angle so as to project in the direction opposite to the long seat surface 21b. A structure is adopted in which the second closing surface 53 (53a, 53b) is closed. Further, the distance between the second closed surface 53 (53a, 53b) and the surface facing the second closed surface 53 (53a, 53b) is substantially the same as the length of the protrusion 13 (13a, 13b) in the vertical direction. is there. Further, the guide grooves 31 (31a, 31b) are slidably engaged with the protrusions 13 (13a, 13b).

As shown in FIG. 4A, when the auxiliary seat 100 according to the present embodiment is used, a load is applied to the seat surface unit (long seat surface) 21 when the user sits down. Here, for the sake of clarity, the load applied to the seat surface unit (long seat surface) 21 is shown as a concentrated load. As shown in FIG. 4B, in the vertical direction, a force that tries to rotate acts with b ₀ as a fulcrum. At that time, the contact of the second closing surface 53a and the projection 13a is, that the force acts to the rotation, i.e. the point of action b _1. In this working point b _1, by seating surface unit 21 receives a force from the projection 13a, the balancing of forces in the vertical direction is established. On the other hand, as shown in FIG. 4C, in the horizontal direction, a force that tries to rotate acts with c ₀ as a fulcrum. At that time, the contact of the second closing surface 53a and the projection 13a is, that the force acts to the rotation, that is, the point c _1. At the point of action c ₁ , the seat surface unit 21 receives a force from the protrusion 13a, so that the force balance in the horizontal direction is established.

In this way, the support column 11, the set of protrusions 13 (13a, 13b) and the guide groove 31 (31a, 31b) have the strength to support the force applied to the action point b ₁ and the action point c ₁ , so that the user can use the strength.
