Abstract: The present disclosure provides a wheelchair restraint apparatus that renders easy adjustment of a restraining position of a wheelchair inside a vehicle. One aspect of the present disclosure is a wheelchair restraint apparatus configured to restrain a wheelchair inside a vehicle. The wheelchair restraint apparatus includes a main body having a seat belt, and a restrained mechanism to and from which the wheelchair is attachable and detachable; and a slide mechanism configured to cause the main body to slide with respect to the vehicle. The restraint mechanism is configured to restrain the wheelchair in a state where a part of the wheelchair is inserted to the restraint mechanism in a traveling direction of the wheelchair.

Abstract: The present disclosure provides a wheelchair restraint mechanism that renders easy alignment between a striker and a latch. One mode of the present disclosure is a wheelchair restraint mechanism for restraining a wheelchair to a restraining member installed on a vehicle. The wheelchair restraint mechanism includes an engagement target portion and an engagement portion. The engagement target portion includes a striker having a rod shape extending in up-down directions. The engagement portion includes: a housing member to house the striker; a latch to limit separation of the striker from the housing member; and a guide member to guide the striker towards the housing member. The guide member includes a first guide surface and a second guide surface, which face each other in width directions of the wheelchair and have a distance therebetween decreasing towards the housing member.

Abstract: A seat back for a vehicular seat has a plate member for supporting a back of a pad and an elastic support mechanism for elastically holding the plate member for moving the plate member in a forward and backward direction with respect to a seat back frame. The plate member includes a first plate portion, a second plate portion positioned on the lower side of the first plate portion, and a third plate portion positioned on the lower side of the second plate portion. The first and third plate portions are more narrow than the second plate portion. The elastic support mechanism includes a rod-shaped elastic bridge member extending horizontally over the seat back frame on the back of the second plate portion. In addition, the elastic bridge member includes a bent portion at the center position as bent along the second plate portion toward the first plate portion.

Abstract: A seat back for a vehicular seat has a plate member for supporting a back of a pad and an elastic support mechanism for holding the plate member for moving the plate member in a forward and backward direction. The plate member includes a thoracic vertebra avoiding portion having at least one of a hole and a recessed portion recessed in a direction away from the thoracic vertebrae of a user, so as to avoid a pushing force to the thoracic vertebrae. In addition the thoracic vertebra avoiding portion is vertically elongated at a substantially widthwise center position of the plate member and has a width of 40 to 100 mm.
