摘要:
The present invention is directed to a vehicle seat suspension apparatus that is mechanically simple, inexpensive, occupies little space, and operates effectively with force inputs from any horizontal direction. The invention comprises a base, an isolator, and a plurality of links connected to both the base and isolator so that the isolator is suspended from the base and can move or swing horizontally in all directions relative to the base. The isolator has an upper plate with two flanges that depend from the plate. The base is positioned directly below the upper plate and between the two flanges. The links are connected to the base and the flanges of the isolator by means of ball and socket connectors that permit the isolator to move in all horizontal directions relative to the base. A travel limit system is used to permit adjustment in the travel of the isolator relative to the base.

The present invention concerns a system for measuring the vibration an operator of a piece of the equipment encounters while operating the equipment. The system includes at least one motion measuring means, such as an accelerometer. The accelerometer may be affixed to the equipment or integrated into the equipment. In addition, motion data recording equipment that is in electrical communication with the accelerometer may also be provided. An alarm may be used to indicate that a preset limit has been or is about to be exceeded.

A first separable pivot is at the height of the pelvis of an occupant and has a guide for supporting a back rest while the support thereof is being transferred from the first separable pivot to a second separable pivot near the bottom of the back rest. A pin secured to the back rest is positioned in a toothed slot for different positions of tilt while the first pivot is engaged and during folding is positioned in an adjusting arcuate slot for maintaining the second pivot engaged.

The present disclosure is directed to an automatic seat height system that adjusts a seat height. The height of a seat is adjusted only when a calculated seat height is outside of the range of a desired seat height. The seat is adjusted only when a seat height change from the desired seat height is not due to external forces such as vibration or shock. The seat height apparatus comprises a sensor, a height adjustment apparatus, a controller and a controllable actuator all in operable communication. The controller comprises software that calculates a calculated seat height based on a measured raw seat height. The calculated seat height is a time history position value pattern. The controller then compares the calculated seat height to a desired seat height to determine a change factor. If the change factor is outside of a predetermined range, the controller directs the controllable actuator to change the height of the seat to bring it within the range.

An apparatus for moving a seat cushion of a seat on which the operator sits includes a seat frame and a pan supporting the seat cushion that is movably supported on the seat frame for movement relative to the seat frame, such as forward-backward or tilting movement. A control panel is mounted to the pan at a forward end of the pan and accessible by the operator while seated on the seat cushion. The control panel includes a housing defining a ledge that is configured so that the operator can grasp underneath the ledge with the operator's hand, with the thumb at an upper face of the control panel. An actuator button is supported on the housing at the upper face of the control panel for actuation by the thumb of the operator while grasping the ledge. A mechanism is connected to the actuator button and is configured and operable upon actuation of the actuator button to permit movement of the pan relative to said seat frame. In one embodiment, two push buttons are provided connected to corresponding extension and tilt mechanisms.

A pivoting seat for a vehicle comprises a seat frame mountable to the vehicle, the seat frame including a pivot mount and a plurality of roller assemblies. A seat cushion assembly includes a seat cushion and a seat pan assembly supporting the seat cushion that is pivotably mounted to the pivot mount so that the seat cushion assembly is pivotable relative to the seat frame. The seat pan assembly includes a flat perimeter plate at an outer perimeter of the seat pan assembly, wherein each of the plurality of roller assemblies is arranged to contact the flat perimeter plate to support the seat cushion assembly while permitting pivoting of the seat cushion assembly relative to the seat frame.
摘要:
A seat suspension system for a vehicle comprising a system frame, an elongated seat bracket having one end pivotably mounted to said system frame and the opposite end adapted to support a seat, and a dampening device attached between said system frame and a location on said seat bracket between said one end and said opposite end thereof.
