A seat apparatus includes a vehicle seat including a cushion member having a bottom portion with a plurality of recessed portions, a plurality of air cells configured to expand by injection of compressed air, and a fluid supply mechanism configured to supply the fluid to the air cells. In the seat apparatus, at least one of the recessed portions is provided at a portion of the bottom portion of the cushion member positioned at a seating portion of the vehicle seat, the hip of a passenger being placed on the seating portion. Each air cell is expandable in a corresponding one of the recessed portions. The fluid supply mechanism is configured to expand at least one air cell by supplying the compressed air thereto and to change the at least one air cell to be expanded by switching a fluid supply destination.

A vehicle seat system is disclosed. The disclosed system may include a stowable back support portion configured to interface with the back of a user (e.g., a passenger and/or driver, as desired). In some embodiments, the support portion may be connected to a guide system for stowing within an interior hollow of the secondary seat portion (e.g., pillion) of a vehicle seat. In some other embodiments, the support portion may be a separate structure configured to be removably stored within the interior hollow and installed at a corresponding mounting site on the vehicle seat or host platform. In some still other embodiments, the support portion may be a rearward portion of the vehicle seat which is attached to the remainder of the vehicle seat by a hinge or other pivoting element which permits the rearward portion to rotate into position.

A battery attaching/detaching structure for a saddle-type vehicle including: a plurality of substantially rectangular parallelepiped batteries for supplying electric power to a power source of the saddle-type vehicle; a battery case in which the batteries are stored; battery-side terminals provided on lower surfaces of the batteries; and case-side terminals engaged with the battery-side terminals, comprises terminal holders that support the case-side terminals such that the case-side terminals are movable between a connected position where the case-side terminals are connected to the battery-side terminals and a retracted position where the case-side terminals are separated from the battery-side terminals. Between the case-side terminals and the terminal holders, springs for urging the case-side terminals in a direction of pressing the battery-side terminals are disposed. Such battery attaching/detaching structure is capable of limiting the movement of a stored battery and maintaining good electrical connection between a battery-side terminal and a case-side terminal.

A rotary knob that rotates in a pushed state includes an extending portion extending in a rotation direction of the rotary knob, and the extending portion includes a cutout portion cut out so as to prevent a first switch that detects that the rotary knob is pushed in from being pressed in a case where the rotary knob is in an intermediate range in which the rotary knob is in a pushed state.
