Combat vehicle seat installation for protection of occupants from the effects of ground explosions
10150392 · 2018-12-11 ·

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.

Seat modules for a mining vehicle

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.

Seating system with automatic weight compensating energy attenuation

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.

SEAT ASSEMBLIES HAVING FIXED FRAMES AND MOVABLE SEAT CUSHIONS AND MOVABLE SEAT BACKS WITH VERTICAL DAMPERS AND CLAMPS COUPLING THE VERTICAL DAMPERS TO THE FIXED FRAMES

A kinetic seat assembly including a primary seat cushion frame including a rear rod extending between opposite rails, a secondary seat back frame movable relative to the primary seat cushion frame, a pair of clamps provided on the rear rod of the primary seat cushion frame, and a pair of vertical dampers coupled between the secondary seat back frame and the pair of clamps on the primary seat cushion frame, each clamp receiving an end of a corresponding vertical damper. In embodiments, the vertical dampers are arranged in a V-shape such that the vertical dampers are oriented at an angle relative to one another such that a distance between a first end of each vertical damper is greater than a distance between a second end of each vertical damper.

Safety structure with energy absorber(s) and motion control assembly for rearward-facing occupant
12083937 · 2024-09-10 · ·

A safety structure includes a seat, having a base and a seatback, a motion control assembly, and an energy absorber. The motion control assembly is configured to translate and/or rotate during a collision. The energy absorber includes a first end configured to couple to the seatback proximate the base, and a second end configured to couple to a structural support of a vehicle. The energy absorber is configured to deform during the collision to absorb energy and based on the translation and/or rotation of the motion control assembly.

Extended stroke energy attenuator

Methods and apparatus are provided for an energy attenuating vehicle seating system that includes a seat configured for guided motion relative to a vehicle compartment over a stroking distance, and an energy attenuating component with a first end attached to the seat, a second end configured for attachment to the vehicle compartment, and an intermediate point configured for guided motion relative to the vehicle compartment. The energy attenuating component is configured to remain rigid and prevent the seat from moving under loads less than a predetermined threshold value, yet deform in a progressive, predictable manner in response to a load exceeding the threshold.

Shock attenuating mounting
