A seat rail system for a vehicle includes an upper rail and a stationary lower rail attached to a floor structure. The upper rail is attached to a vehicle seat and is movable relative to the lower rail. The upper rail comprises first and second side sections with a cavity between the side sections. The lower rail includes first and second lateral side elements respectively connected to the first and second side sections. An elongated load member is attached to the lower rail, where an upper part of which extends into the cavity. A lower part of the load member is connected to the floor structure. The first lateral side element blocks lateral movement of the first side section and the second lateral side element blocks lateral movement of the second side section upon deformation of the upper rail in a vehicle impact event.

A vehicle seat is provided. The vehicle seat includes a cushion frame, a coupling bracket including a coupling portion and a flange portion, a lifter link, and a fixing member. The coupling portion includes a plate panel which, is substantially orthogonal to a fixing face of the fixing member, and substantially parallel to a seat front-rear direction. An end face of the plate material is welded to the fixing face. The flange portion protrudes in a seat width direction from one end in the seat front-rear direction of the coupling portion, includes a plate panel substantially orthogonal to the fixing face, and is integrally molded with the coupling portion.

A vehicle passenger detection apparatus is configured to monitor an occurrence of a passenger entering into a vehicle from a vacant seat state or an occurrence of the vacant seat state due to the passenger exiting from the vehicle, and to determine by calculations whether a detection value of a load sensor is stable before the passenger entered the vehicle or after the passenger exited the vehicle. Updating of a passenger determination result is executed even in a state in which a determination result from a vibration change amount judgment section indicates a disturbance has occurred, when the vehicle entry and exit determination section determines that the detection value of the load sensor is stable before the passenger entered the vehicle or after the passenger exited the vehicle.

A cushion frame for a conveyance seat is provided. The cushion frame comprises a first and a second side frame; a connecting member that couples the first side frame to the second side frame; a fixing bracket that comprises a first and a second fixing part; and a belt anchor that is disposed in the fixing bracket and is coupled to a seat belt. The first fixing part comprises a first plate-surface that is substantially parallel to a seat-width axis. The second fixing part comprises a second plate-surface that is substantially perpendicular to the first plate-surface and is situated in the opposite side of the second side frame across the first side frame. The belt anchor is fixed to the second fixing part.

A track assembly includes a track, a support member, and/or a lever. The support member may be connected to the lever, and/or the lever may include a rotational axis substantially parallel to the track. The lever may rotation about the rotational axis between a first position and/or a second position. The lever may be configured to engage the track in a longitudinal direction when the lever may be in a first position. The lever may be configured to engage the track in a lateral direction when the lever may be in a second position. The lever may be configured to limit longitudinal movement of the support member along the track. The track may include a longitudinal window that may have a first edge and/or a second edge.

A track assembly includes a track, a support member, and/or a lever. The support member may be connected to the track, and/or the lever may be connected to the support member. The lever may include a rotational axis substantially parallel to the track. The lever may rotate about the rotational axis between a first position and a second position. The lever may limit movement of the support member relative to the track in a first direction, and/or the lever may not limit movement of the support member relative to the track in a second direction. The lever may be configured to contact the track. The track may include a window having a first edge and/or a second edge.

A track assembly includes a track, a support member, a lever, and a slider. The support member may be configured for selective connection with the track. The lever may be connected to the support member, and the slider may be connected to the support member. The lever may be configured to limit movement of the slider and to limit movement of the support member. The slider may be configured to move longitudinally along the support member. The slider may be connected at a top of the support member. The lever may be configured to rotate about an axis that may be parallel to the track. The lever may include a top portion. The lever may include a first position and/or a second position. The slider may be configured to selectively contact the top portion of the lever when in a first position.

A support assembly includes a support member, a side member, and a resilient member. The support member may be configured to engage a track. The resilient member may be connected to the support member, and/or the support member may be connected to the side member. The resilient member may be configured to compensate for different orientations of the side member. The resilient member may be configured to maintain a position of the side member relative to the track. The resilient member may be configured to compensate for different lateral positions of the side member relative to the track. The resilient member may be connected to a lateral side of the support member. The resilient member may be disposed proximate a first end of the support member, and/or a second resilient member may be disposed proximate a second end of the support member.

A cam assembly includes a pin, a first cam, a second cam, and/or a bearing. The first cam may be connected to the pin, and/or the second cam may be connected to the pin. A bearing may be configured to rotatable support the pin. The second cam may include a first portion and/or a second portion. The first portion of the second cam may be configured to contact a track in a first vertical position of the pin. The second portion of the second cam may be configured to contact said track in a second vertical position of the pin. The first portion may be vertically offset from the second portion. The first position of the pin may correspond to an unloaded state. The second vertical position of the pin may correspond to a loaded state.

In an arrangement which includes a seat support body slidably supported on a fixed rail fixed to a floor; a power supply device supplying power to an electrical component on a seat side; and a drive device driving the seat support body in a front-and-rear direction and having a motor and a transmission member disposed so as to pass longitudinally through an interior of the fixed rail, the power supply device includes: a housing housing an electric wire for power supply; and a slider linked to the seat support body and slidable within the fixed rail. The electric wire is drawn out from the housing, retained by the slider and slidable within the fixed rail. The slider has an interference-avoiding portion for avoiding interference with the transmission member disposed so as to pass longitudinally through the interior of the fixed rail. Accordingly, the transmission member of the drive device and the slider for retaining the electric wire, which slides within the fixed rail, can be arranged in proximity to each other within the fixed rail while avoiding interference therebetween, thus enabling simplification and a reduction in the size of a rail structure.
