A vehicle seat assembly including a seat frame assembly including a seat base and a seat back pivotally connected to the seat base. The seat back includes at least one resin fuse arranged in the seat back to indicate structural loading in the vehicle seat assembly above a tolerance loading. The at least one resin fuse includes an aperture extending through the seat back and comprising a flange encircling the aperture and extending generally perpendicular to the seat back, and an indicator bar extending across a diameter of the aperture. The aperture is open on either side of the indicator bar.

A space management system for managing an environment of a shared space that is arranged inside a mobile body and can be used jointly by a first occupant and a second occupant comprises a control mode determining unit configured to determine a control mode serving as a control target of an adjusting unit configured to adjust the environment of the shared space. The control mode determining unit is configured to determine enabling or disabling of an independent control mode for independently adjusting an environment of a first subspace, which is a part of the shared space, where the first occupant is present and an environment of a second subspace, which is a part of the shared space, where the second occupant is present.

A pivot fitting for a seat, in particular vehicle seat, is configured to adjust an inclination of the seat between at least a use position and at least a non-use position. The pivot fitting may have at least one detection unit which is configured to determine if the seat is in at least one of the use position, any intermediate inclined position or the non-use position.

A vehicle seat comprising a seat back with a seat back frame, a seat cushion with a seat cushion frame and one first and second links. The first link is mounted pivoting relative to the seat cushion frame around a first transverse axis, and relative to a seat support around a second transverse axis. The second link is mounted pivoting relative to the seat cushion frame around a third transverse axis, and relative to a seat support around a fourth transverse axis. The first and second links are configured in order to allow lifting a rear part of the seat cushion frame relative to said seat support.

A method for operating a vehicle seat device for motor vehicles, which has a vehicle seat with a seat part and a backrest, associated with the seat part, and at least one actuator which is associated with the seat part and/or the backrest and by means of which the vehicle seat can be brought automatically into a sitting position and into a reclining position, wherein the movement takes place as a function of a desired position that can be specified by a user and of at least one detectable vehicle seat state. It is provided that a current temperature is monitored as the vehicle seat state and that if the monitored temperature falls below a limit temperature, the vehicle seat is brought into a sitting position or left in a current sitting position regardless of the desired position.

The present disclosure relates to a vehicle seat frame structure comprising a backrest frame part and a seat cushion frame part. The backrest frame part and the seat cushion frame part are supported by a pivot bearing for being pivoted about a pivot axis. A spring device is biased with the pivoting movement. The spring device is only effective in a comfort inclination angular region. If the backrest frame part is pivoted out of the comfort inclination angular region towards the front, the spring device is released from the force flow between the backrest frame part and the seat cushion frame part. The release is provided by a shaft-hub-connection between a coupling section of a shaft and a hub of a hub body, the shaft-hub-connection comprising an angular clearance.
