Definitions
- the present invention relates to a vehicle seat that is suitable as a seat for a so-called welfare vehicle, for example, because the ability of an elderly person, a disabled person or the like (hereinafter also simply referred to as a seated person) to get on and off the vehicle together with a wheelchair.
- Japanese Patent Application Laid-Open No. 2003-339773 discloses a technique related to this type of sheet.
- a wheelchair that travels by manually rotating a large-diameter rear wheel (manually operated wheel) while a seated person is seated is separably connected to a seat moving device mounted in the passenger compartment.
- the vehicle seat allows the seated person sitting in the wheelchair to move freely away from the vehicle and to the vehicle while sitting in the wheelchair. It is very easy to get on and off.
- all the wheels of the seat device used as a wheelchair by separating the force of the seat moving device are of a small diameter, and therefore it is a problem in the case of a wheelchair that is mainly pushed and moved by a caregiver.
- a seat device (wheelchair) that is self-propelled by rotating itself needs to be able to rotate easily when seated, and the hip point of the seated person is set to 700 mm or more from the road surface. Therefore, the diameter of the rear wheel for manual operation is set to be much larger than that of the front wheel.
- This manually operated wheel is normally used in a state where it is supported near the waist height of the seated person and the seat cushion force protrudes downward.
- the height of the seat device in the passenger compartment (so-called hip point) is set to the same level as other passenger seats. It is necessary to set it low, for this purpose when moving the seat device into the passenger compartment.
- the manually operated wheel must be displaced upward with respect to the seat body to reduce the downward protrusion from the seat cushion.
- rear wheel brackets are provided on both sides of the seat frame supporting the seat body so as to be pivotable up and down.
- a configuration was adopted in which an axle was attached to the front end side and the manually operated wheel was supported for rotation. According to this conventional configuration, the manually operated wheel can be moved to the lower use position (grounding position) and the upper storage position by rotating the rear wheel bracket up and down.
- An object of the present invention is to provide a vehicle seat that can be set and does not give a seated person a tight thought or posture as before.
- the present invention provides a vehicle seat having the structure described in each claim.
- the rear wheel bracket positions the axle on the front side and the lower side with respect to the support shaft.
- the rear wheel is fixed at a position where it can be grounded.
- the rear wheel bracket is rotated about its support shaft so that the axle is positioned rearward and upward with respect to the support shaft. Since the axle is positioned rearward and upward with respect to the support shaft, the rear wheel is not positioned on the side of the seated person, but is stored in a position shifted rearward from the side of the seated person.
- the wheel bracket is configured to be rotated in a direction to move the axle forward and upward with respect to the support shaft.
- the rear wheel is configured to be stored at a position shifted to the front side with respect to the use position, and thus is configured to be stored on the side of the seated person.
- the rear wheel is stored above and behind the use position and is not positioned on the side of the seat occupant. You can't have a cramped attitude that you can't do the cramped thought!
- the axle is moved above the support shaft, so that the rear wheel can be stored sufficiently above the use position, thereby increasing the seating surface height of the seat device. It can be set to be equivalent to the passenger seat.
- a large manually operated wheel that is set to have a larger diameter than the front wheel for the seat occupant to directly rotate is operated with a lateral force behind the seat occupant. Stored at a shifted position.
- the invention according to claim 1 can achieve a particularly great effect when the rear wheel is a manually operated wheel having a large diameter.
- the position where the side force of the seated person is shifted rearward means that the end of the rear wheel or manually operated wheel is generally the seat cushion in view of the side force.
- the conditions for the storage position of this rear wheel or manually operated wheel should be interpreted gently, even if the rear wheel or manually operated If the occupant does not feel cramped due to the presence of a ring and is not forced to cramp, the position can be set as the storage position according to the present invention.
