A passenger seat system) for a transport means has an elongate carrier structure, to be attached, fixedly with respect to a structure, mutually spaced-apart raster openings on the carrier structure top side, and a seat having a seat frame. The seat frame is displaceable and arrestable on the carrier structure, has a bottom side lying on the carrier structure, a top side holding a seat surface, an arresting device on the bottom side and an operating unit coupled to the arresting device, and movable into an arresting position and an unlocking position. The arresting device has an arresting body, mounted so as to be movable perpendicularly with respect to the carrier structure and pushed by a spring device, by a spring force, into an arresting position, and a locking unit for automatically holding the arresting body in the arresting position when the arresting body reaches the arresting position.

A vehicle seat includes a seat framework configured including a first frame and a second frame that are capable of supporting an occupant, and a link including a first swing shaft via which the first frame is coupled to one end side of the link and a second swing shaft via which the second frame is coupled to another end side of the link; a first cover that is attached to a back face of the first frame on an opposite side from a front face configured to support the occupant, that covers a back face side of the first frame; and a second cover that is attached to a back face of the second frame on an opposite side from a front face configured to support the occupant, that covers a back face side of the second frame.

A vehicle occupant protection structure includes a seat body including a seatback configured to support a back of an occupant, and a shell section including a portion configured to face a side of the occupant whose back is supported by the seatback and the portion configured to restrict movement of the occupant in a seat width direction in a case of a vehicle collision.

A vehicle includes an internal combustion engine; an engine body at least partially located at a center in a vehicle width direction; a first chamber provided in an exhaust passage extending from the engine body; and a second chamber provided downstream of the first chamber in the exhaust passage, in which the first chamber and the second chamber are each located behind the engine body, and at least a part of the first chamber and at least a part of the second chamber overlap the engine body in a vehicle width direction and a height direction, respectively. This vehicle structure can contribute to downsizing of an exhaust system of an internal combustion engine in a vehicle including a vehicle frequently used to travel on an uneven ground.

The seat bracket structure has a floor cross member linking a side sill and a floor tunnel of a vehicle to each other and a plurality of seat brackets disposed frontward and rearward of the floor cross member in a vehicle front-rear direction and linked to the side sill or the floor tunnel and to the floor cross member. The seat brackets each include a main body portion that forms a hollow section with a floor panel as a bottom surface and is spaced away from the floor cross member and a linkage portion that extends from the main body portion in the front-rear direction, is joined to the floor panel, and is linked to a flange which is a lower edge portion of the floor cross member.

The window frame member has a horizontal bar shape, disposed between the upper window panel and the lower window panel and supports a lower end of the upper window panel and an upper end of the lower window panel. The window frame member has opposite longitudinal ends fixed to a B pillar and a C pillar, vertical pillars of the vehicle cabin, respectively. The seat cross member also has opposite longitudinal ends fixed to the B pillar and the C pillar. The window frame member and the seat cross member overlap each other at least partially in a portion along a vehicle height, and extend with a horizontal gap disposed therebetween over their entire lengths. The horizontal gap is less than a horizontal width of each of the window frame member and the seat cross member.

A seat support of the conveyance seat includes right and left front foot members that are attached to a body floor with a gap therebetween in a seat width direction and extend to protrude upward from the body floor and a foot linking member that links the upper portions of the right and left front foot members and is disposed to partially overlap the right and left front foot members in the up and down direction. A closed section structure is formed by an opposing wall portion disposed at a position opposing the foot linking member in an up and down direction, right and left side wall portions continuously bent from both end portions of the opposing wall portion in a seat width direction and protruding to abut toward the foot linking member in the front foot member, and the foot linking member.
