The disclosure relates to a seat arrangement comprising a seat. The seat is arranged to be suspended on a support structure by a first resilient member and a second resilient member attached to opposite longitudinal and/or lateral sides of the seat. The first and second resilient members are attached to the seat at a seat end of the first and second resilient members and to the support structure at a support structure end of the first and second resilient members respectively. When a load causes translational and/or rotational movement of the seat in a y-z plane of the seat, elastic shear deformation in the first and second resilient members controls the translational and/or rotational movement of the seat.

A seat installation for a combat vehicle which protects an occupant from the effects of an explosion detonated beneath the vehicle in which breakaway structures are interposed between a seat pan and the vehicle floor which initially rapidly drives the seat up after the explosion, but which quickly breaks away to avoid spinal compression injury. A crushable energy absorbing structures thereafter absorb the floor motion, each structure comprised with a vertical stack of crushable energy absorbing cells which are successively crushed at higher force levels to adapt the seat installation to varying weight occupants. A pivoted foot rest provides spaced above the floor which mitigates injuries to the feet and legs by allowing the feet to avoid contact with the floor and which swing up and away from the floor while avoiding tipping of the seat.

A mining shuttle car that trams on underground roadways includes a conveyor system and an operator's compartment adjacent to the conveyor system. The operator's compartment includes a rotatable seat and a control station. The operator's seat module is coupled to one or more joysticks that control the car, and the operator's seat module and the control station are mounted on a rotatable platform so as to be rotatable as a unit between a plurality of secured positions for operating the mining shuttle car. Forward movement of the joystick control relative to the seat steers the shuttle car about a point in front of the seat, and rearward movement of the joystick control relative to the seat steers the shuttle car about a point behind the seat. Forward and rearward movement of one of the joysticks steers the mining shuttle car in the same manner regardless of the rotational position of the rotational position of the seat.

Provided is a vehicle seat fastening structure that enables a reduced length of a bolt for fastening a movable rail and a cushion frame in a spaced-apart manner. The cushion frame includes a bottom wall extending in a seat-width direction and a seat front-rear direction. The nut includes a body having a cylindrical shape and configured to penetrate the bottom wall, a thread groove, and a flange portion projecting radially from the body. A length of the nut along a central axis thereof is greater than a separation distance between an upper surface of the movable rail and an upper surface of the bottom wall of the cushion frame in a state in which no impact is applied to the cushion frame. The flange portion is provided in an area of the nut at a distance from an insertion opening for the bolt greater than the separation distance.

A method and a system are configured to control an actuator for imposing forces in an adjusting direction, in particular a vehicle longitudinal direction from a vehicle front towards a vehicle rear, onto a loading surface, such as a vehicle seat, which is adjustably mounted on a body of a motor vehicle. A collision-based event is anticipate or detected. An actuator is activated in response to detection of the collision-based event in order to activate an actuator-driven movement of the loading surface relative to the body in adjusting direction for influencing, and in particular decelerate a collision-based movement of the loading surface relative to the body against the adjusting direction.

Ramp mounts may facilitate the movement of a. passenger seat pan relative to a passenger seat frame during movement of the seat pan between an upright position and a recline position relative to the passenger seat frame. During cycling of the seat pan from the recline position to the upright position, ramp mounts may break. Embodiments of the ramp mount (16) disclosed herein may increase the ramp mount durability so as to reduce the instances of ramp mounts breaking during cycling of the seat pan between the recline and upright positions. Additionally, some embodiments may provide for a ramp mount that has fewer components. Such embodiments may simplify coupling of the ramp mount to a seat pan and may reduce passenger seat system assembly time. Moreover, in some embodiments, the reduced number of components may further reduce manufacturing time and/or costs thereby providing a relatively low cost ramp mount.

Methods and apparatus are provided for a self adjusting energy attenuating vehicle seating system configured to automatically compensate for variations in the weight of seated occupants. A seat is mounted in a vehicle and configured to stroke in a downward direction, generally toward a floor of the vehicle, with an adjustable energy attenuating device disposed in a load path between the seat and a rigid structural portion of the vehicle. A signal processor removes variations in a seat weight signal attributable to vehicle or occupant motion, and outputs an energy attenuator adjustment signal corresponding to the weight of a seated occupant. The system may further include an actuator configured to receive the energy attenuator adjustment signal and adjust a load setting feature of the energy attenuating device accordingly.

A vehicle seat control device includes a collision prediction part that predicts a collision direction of a collision occurring in a vehicle, a first driving part that rotates a vehicle seat around an axis of the vehicle in a substantially upward/downward direction, and a controller that controls the first driving part such that a direction of the vehicle seat is changed to an opposite direction with respect to the collision direction on the basis of the predicted collision direction.

Provided is a vehicle seat control device which includes a collision prediction unit (50) which predicts whether a collision will occur in a vehicle and a time before the collision will occur, driving units (14a and 18a), each changing at least one of a position and a posture of a vehicle seat (10), and a control unit (80) which controls the driving units to bring the vehicle seat close to a target state during the time before the collision predicted by the collision prediction unit occurs.

Embodiments disclose a vehicle including: a magnet unit disposed under a seat and on which a plurality of magnets are disposed; an electromagnetic unit disposed on a floor of a vehicle compartment and including a plurality of electromagnets; and a control unit configured to control the electromagnetic unit, wherein the control unit moves the seat to a preset position on the electromagnetic unit by controlling current applied to each of the electromagnets. Accordingly, the vehicle can improve the degree of freedom in design in a vehicle compartment while providing a passenger's convenience by implementing a seat movement mechanism suitable for the era of autonomous traveling.
