An apparatus including a sensor and a control unit. The sensor may be configured to determine seat orientation information. The control unit may comprise an interface configured to receive the seat orientation information. The control unit may be configured to analyze the seat orientation information, determine when to deploy a corrective measure and modify the corrective measure in response to the seat orientation information. The control unit may deploy the corrective measure using a default arrangement in a first mode. The control unit may deploy the modified corrective measure in a second mode.

Methods and apparatus are provided for a shock attenuation device configured to operate between a structure and a mass that is supported by and moveable relative to the structure in a guided manner along a stroking direction. In one embodiment, a notch load portion is configured to provide a resisting force to relative displacement of the supported mass over a first stage stroking distance according to a predefined load profile that includes a spike load peaking at a first threshold load value at the onset of relative displacement, and a substantially constant notch load for a remainder of the first stage stroking distance. A constant load portion arranged serially with the notch load portion is configured to provide a substantially constant resisting force to displacement of the supported mass at a second threshold load value over a second stage stroking distance, wherein the second threshold load value is higher than the first threshold load value.

The disclosure provides for a system. The system may include a rotational control system configured to rotate a seat of a vehicle, and one or more computing devices. The one or more computing devices may have one or more processors that are configured to determine that an impact is imminent at a location on the vehicle along a collision axis. A most favorable orientation may be determined by the one or more processors based on the determined location and collision axis. Using the rotational control system, the one or more processors may rotate the seat of the vehicle to the most favorable orientation in order to reduce risks of serious injury to a passenger in the seat caused by the imminent impact. A translational control system may be used by the one or more processors to translate the seat of the vehicle to a position relative to the determined location.

A vehicle seat 10 has a seat cushion 12, a seatback 14, a fixed supporting portion 24, and a movable supporting portion 26 that is supported by the fixed supporting portion 24 movably at least toward a seat rear side. Further, the vehicle seat 10 has an energy absorbing member 28 that, by being provided between the fixed supporting portion 24 and the movable supporting portion 26, restricts displacement of the movable supporting portion 26 with respect to the fixed supporting portion 24, and, due to the seatback 14 being pushed toward the seat rear side at a time of a collision of a vehicle, the energy absorbing member 28 is deformed and the movable supporting portion 26 is displaced with respect to the fixed supporting portion 24.

A seat rotating device of an autonomous vehicle is provided. The device includes a floor panel on which a plurality of members configuring load paths during a collision are formed. A rotating unit is rotatably installed on the floor panel while supporting a seat and integrally rotates with the seat, and connects the load paths with the members formed on the floor panel.

Various seating arrangements for a vehicle are described. Generally, the vehicle includes an electromagnetic array featured on a floor of the vehicle. The chair includes base having a plurality of magnets featured thereon. The vehicle generates signals for the electromagnetic array to generate a wave and impart a force on the chair in a determined direction via the plurality of magnets.

A method and apparatus for protecting a passenger during a crash comprises a moveable seat with an energy absorber (EA) that allows the seat to stroke a finite distance to decelerate the passenger in a controlled manner. The seat is designed so that one of a plurality of fixed profile EA's can be selectively engaged to provide a tailored EA composite profile adapted to the occupant's weight and anticipated crash environment. The tailored EA composite profile applies a frequency matched, low onset force to the seat, which substantially eliminates problems associated with dynamic overshoot of the passenger's spine.

A passive safety system includes a seat support structure, a seat that is connected to the seat support structure, a motion control device operable to control motion of the seat relative to the seat support structure, a sensor that provides an output signal, and a controller. The output signal is indicative of an imminent collision. The controller causes the motion control device to move the seat relative to the seat support structure in response to the output signal.

A vehicle seat for attaching to a vehicle structure of a vehicle has a seat part and a backrest. The vehicle seat is movable in the longitudinal direction of the vehicle in relation to the vehicle structure and adjustable into a resting or lying seat position. In the event of a collision, the vehicle seat with the seat part is or can be pivoted upwards along an axis extending parallel to the vehicle transverse direction, with a front region facing away from the back rest. The backrest, at least in the resting or lying position, is or can be connected to the vehicle structure of a tensile force transmission element.

An assembly for an energy attenuation system is described. The assembly offers a lower profile configuration that fits better into tight spaces that exist in the compact seats that are required for military helicopters. The assembly includes a cable that is oriented and positioned to work with the profile. The assembly includes an actuator which ejecting the pins in a multi-stage sequence. The design of the assembly also ensures the pins cannot back drive when the pins are in the ejected position. Additionally, the pins may have part commonality reducing a unique part of the assembly.
