Each panel forming a variable mechanism is maintained in a state accommodated on an internal wall surface to secure a cabin space of a mobility, and according to the need of a passenger, the rotational position of each panel is changed so that a shape of the variable mechanism is transformed, providing a convenient function. Accordingly, a space utilization apparatus of mobility that can secure a cabin space by removing an unused space of the cabin space when the convenience function is not used in the cabin space of the mobility, and can improve the space utilization by selectively providing the convenience function.

A cockpit for a motor vehicle is described, comprising: a first seat comprising a first seat cushion and a first backrest; and a second seat comprising a second seat cushion and a second backrest; the cockpit can be shifted into a two-seater configuration, in which the first seat is in a first position, in which it is next to the second seat along a first axis and in which the second seat cushion and the second backrest are arranged in a second and a third position; the first seat can be moved along the first axis between the first position and a fourth position, the second seat cushion can be moved between the second position and a fifth position, and the second backrest can be moved between the third position and a sixth position parallel to a second axis, which is transverse to the first axis; the cockpit is selectively movable to a single-seater configuration, in which the first seat is in the fourth position, the second seat cushion is in the fifth position and the second backrest is in the sixth position; the first seat, in the fourth position, being arranged in the space occupied by the second seat when the cockpit is in said first configuration.

An integrated folding seat and movable backrest includes a mounting frame for all of the elements of the assembly. A vertically movable backrest frame is slideably attached to the mounting frame and coupled to a pivot down seat frame by pivot arms. The pivot arms include a curved upper arm extending between the mounting frame and the seat frame, a lower arm extending between the mounting frame and the seat frame, and a lift arm having one end pivotally coupled to the lower arm at a position intermediate the ends of the lower arm, and an opposite end coupled to the backrest frame.

An aircraft seat assembly including first and second stanchions forming interior spaces open through forward slots. A seat pan is pivotally attached to the stanchions and includes rearward extensions that extend through the forward slots and are received in the interior spaces. First and second spring mechanisms reside in the respective first and second interior spaces and are attached at opposing ends to their respective stanchion and to the seat pan. In use, rotating the seat pan toward a deployed position elongates the first and second elongation springs thereby energizing a return force of the spring mechanisms.
