An assembly for absorbing energy in an overload event has an energy absorber for reducing the load on an object being transported on a loading unit. The energy absorber, in the case of a one-off overload event with an energy input that is sufficiently high that damage to the object would be possible or highly likely in the absence of the energy absorber, to absorb energy in order to reduce the load on the object. Measured values relating to the current state of the loading unit are periodically acquired by a sensor device. A control device identifies an overload event from the acquired measured values. A weight of the object to be transported and a limit value for a load on the object are determined. Following identification of the overload event, damping by the energy absorber is controlled to keep the load on the object below the limit value.

The invention provides a type of all-terrain vehicle seat installation structure; it includes the cab frame and the seat backrest arranged on the frame; the back mounting side of the seat backrest includes the first mounting part and the second mounting part arranged up and down respectively. The first mounting part includes the upper support frame located at the upper end of the frame; the installation hole is arranged on the upper support frame; the installation pin inserted into the installation hole is extended out of the seat backrest. The second mounting part includes the lower support frame located at the lower end of the frame; the lower end of the seat backrest is provided with the installation buckle mounted on the lower support frame. The top of the seat backrest is limited by the installation pin being inserted into the installation hole; the seat backrest is supported by the bottom installation buckle; the top of the seat backrest is limited by the inserting installation structure of the installation pin and the installation hole to avoid the seat backrest moving up and down on the frame, so the stability of the seat installation structure of the all-terrain vehicle is improved. The invention also provides a type of all-terrain vehicle provided with the seat installation structure of the all-terrain vehicle as described above.

A vehicle-mounted seat device includes an SB main frame, a backrest, a relay disk secured at the center in the width direction of the backrest, a plurality of radial wires for suspending the backrest such that the backrest can swing relative to the SB main frame with the relay disk as the center, an SB subframe capable of swinging together with the backrest, a headrest, a headrest stay extending downward from the headrest and mounted on the SB main frame so as to rotate around a rotation shaft; a pressure-receiving body secured on the headrest stay so as to be disposed behind and opposed to the relay disk; and a provisional connection mechanism for provisionally connecting the headrest stay to the SB main frame.

A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

A vehicle seat includes a seat base and a seatback coupled to the seat base. The seatback includes a rigid frame, a first textile layer attached to the rigid frame, a second textile layer attached to the rigid frame, and at least one textile interconnecting tube coupling the first textile layer to the second textile layer. The textile interconnecting tube is attached in tension between the first textile layer and the second textile layer to dampen dynamic loads applied to the seatback. Instead of (or in addition to) the textile interconnecting tube, the seatback may include a plurality of tension elements interconnecting the first textile layer and the second textile layer.

A vehicle seat device includes an SB main frame that is joined to a seat cushion via a reclining shaft; an SB subframe that is swingable with respect to the SB main frame at least about a roll axis; a backrest that is installed on the SB subframe; and a lower support wire and an upper support wire that limit rearward movement of the SB subframe and allow movement of the SB subframe about the roll axis. A straight line connecting between the front end and the rear end of the lower support wire is inclined with respect to a normal line so as to rise toward the front, the normal line being normal to a straight line connecting between an upper end of the SB main frame and the reclining shaft.

A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

A passenger restraint system for roller coasters, designed to maintain a passenger in an essentially upright posture, the passenger restraint system including a fixed column and a seat column designed to support and hold the passenger, which seat column is coupled to the fixed column so as to be movable relative to the fixed column and to be adjustable to the size of the passenger during an embarkation phase. The seat column is coupled to the fixed column by an articulated linkage, and the passenger restraint system further includes a device for balancing the seat column, which balancing device includes a cylinder fixed, at a first articulated end, to the fixed column and, at a second articulated end, to the seat column.

A vehicle seat device includes an SB main frame that is joined to a seat cushion via a reclining shaft; an SB subframe that is swingable with respect to the SB main frame at least about a roll axis; a backrest that is installed on the SB subframe; and a lower support wire and an upper support wire that limit rearward movement of the SB subframe and allow movement of the SB subframe about the roll axis. A straight line connecting between the front end and the rear end of the lower support wire is inclined with respect to a normal line so as to rise toward the front, the normal line being normal to a straight line connecting between an upper end of the SB main frame and the reclining shaft.

A kinetic seat back assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat back assembly includes a primary seat back frame, a secondary seat back frame, a seat back tilt mechanism coupling the secondary seat back frame to the primary seat back frame such that the secondary seat back frame is movable with respect to the primary seat back frame, and an upper pivot mechanism that pivotally couples an upper portion of the primary seat back frame to an upper portion of the secondary seat back frame.
