A vehicle includes a chassis and a seating system. The seating system includes a frame coupled to the chassis, a seat cushion supported by at least one of the frame and a floor of the vehicle, a first recoverable insert configured to provide a first energy attenuation response, and a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response. The seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system.

A vehicle safety device for reducing whiplash in a vehicle includes a curved guide configured to allow a seat to slide thereon, an impact sensor that can detect an impact on a rear end of the vehicle; and a locking mechanism that can allow the seat to slide on the curved guide when an impact is detected by the impact sensor. The locking mechanism can prevent the seat from moving relative to the curved guide when there is no impact detected by the impact sensor.

A method for cancelling seat vibration includes receiving, from an accelerometer, a plurality of accelerometer measurements and applying a first filter to the plurality of accelerometer measurements to remove accelerometer measurements of the plurality of accelerometer measurements having a frequency above a first threshold frequency. The method also includes applying a second filter to an output of the first filter to remove accelerometer measurements of the output of the first filter having a frequency above a second threshold frequency and applying a third filter to an output of the second filter to generate an accelerometer measurement output having a center frequency corresponding to a resonant frequency of the vibration of the at least one component of the seat. The method also includes determining an absolute magnitude value of the accelerometer measurement output and selectively controlling a motor based on the absolute magnitude value of the accelerometer measurement output.

A vehicle seat to be mounted on a vehicle includes a seat cushion and a seat surface lowering mechanism. The seat cushion includes a seat surface on which a waist of an occupant of the vehicle is to be placed. The seat surface lowering mechanism is configured to lower the seat surface in response to either one of an occurrence of a rear-end collision of the vehicle or a sign of the occurrence of the rear-end collision.

A seat support structure for a working vehicle comprises a fixed plate, a parallel link mechanism, a supporting plate, a rotation shaft, a rotation plate, a seat, a rear upper shaft, and a rotation lock unit. The fixed plate is fixed on a vehicle body of the vehicle. The parallel link mechanism includes a front link and a rear link. The supporting plate is connected to the fixed plate via the parallel link mechanism. The rotation shaft is fixed on a center portion of the supporting plate. The rotation plate is rotatably supported on the rotation shaft. The seat is attached to the rotation plate. The rear upper shaft connects the rear link to the supporting plate. The rotation lock unit is provided on the rear upper shaft.

A vehicle seating assembly includes a seatback and a seat base. The seat base is operably coupled to the seatback. The seat base includes a first suspension assembly and a second suspension assembly. The first suspension assembly includes a seat pan assembly and a seat cushion assembly. The seat cushion assembly is positioned above the seat pan assembly. The second suspension assembly includes a plurality of independent thigh supports operably coupled to a forward portion of the seat pan.

The invention relates to a device for damping an upper suspension part in at least one spatial direction (X, Y, Z) with respect to a lower suspension part movable relative thereto, wherein a spring apparatus which acts between the upper suspension part and the lower suspension part is provided for damping, wherein an actuating element is provided by way of which a force can be introduced into the device bidirectionally in the operating direction of the spring apparatus, wherein the actuating element is actuable via a control apparatus.

The invention relates to a vehicle seat or a vehicle cab with a suspension system comprising an upper closing part and a lower closing part which is deflectable in relation to the upper closing part, which closing parts are operatively connected to each other in a resilient manner by means of a suspension element, and with a damping system for damping vibrations acting on at least one of the two closing parts, wherein an electromagnetically acting damping and height-levelling unit is provided which is arranged between the two closing parts in such a manner that said damping and height-levelling unit acts on the upper of the two closing parts in the vertical direction of the vehicle both in a vibration-insulating and also height-levelling manner.

An auxiliary tractor seat for providing additional seating in a tractor cabin is provided herein. The auxiliary tractor seat includes a mounting plate defining one or more mounting holes, configured to receive an auxiliary tractor seat bolt, so as to couple the auxiliary tractor seat to tractor seat. A base plate is coupled to the mounting plate so as to provide a substantially flat seating surface. A lower seat back coupled to at least one of the mounting plate and the base plate, an upper seat back at least partially disposed above the lower seat back, and a hinge coupled to the lower seat back and the upper seat back so as to permit the upper seat back to transition from an upright position to a horizontal position. The auxiliary tractor seat is coupled to the tractor seat such that suspension supports the auxiliary seat and provides shock absorption.

The operation in a closing direction and the operation in an opening direction of a storage rack are performed efficiently with small force. Fixed frames and a storage rack are connected by link mechanisms, and the link mechanism includes fixed-side links linked to the fixed frame and movable-side links linked to the storage rack. When a position of one ends of the movable-side links is located closer to one ends of the fixed-side links than a balanced point, the elastic member biases the storage rack in an open-position direction. In the open position, since the elastic member biases the storage rack in the opening direction, an open state is maintained as long as the position of the one ends of the movable-side links does not return to the change point position. Accordingly, the open position can be held by a simple structure without using electric power.
