Abstract
A vehicle seating system includes a top frame for mounting to a vehicle seat. The top frame has integral rails or channels with roller tracks at one end and vibration dampening systems at the other. An opposing pair of the roller tracks includes a vibratory dampening or regulation system that controls the amount of fore and aft travel of the top frame.
Claims20
A system that facilitates vibratory dampening, comprising:
- a connector block configured to fixedly connect to a cross-member, wherein the cross-member is in communication with a seat assembly, and wherein the connector block travels linearly within a channel of a seat mounting frame in synchronization with the seat assembly;
- and
- a pair of compression mechanisms, each of the compression mechanisms having an inner and an outer end, wherein the inner end of each of the compression members is attached to opposite ends of the connector block:,
- a pair of alignment mechanisms for aligning the pair of compression mechanisms and the connector block within the channel of the seat mounting frame, wherein the outer end of each compression member is attached to a respective alignment mechanism, wherein the connector block is attached to the alignment mechanisms only through the compression members, and wherein the connector block and the pair of compression mechanisms are configured to dampen linear vibration upon being installed within the channel of the seat mounting frame.

A system that dampens fore-aft vibrations, comprising:
- a seat assembly attached to a platform, wherein the platform includes at least one cross-member that traverses a width of the platform, and wherein the cross-member traverses in a linear direction within a track;
- and
- a coil assembly that dampens fore-aft vibrations transferring into the platform, wherein the coil assembly is fixedly attached to the cross-member and wherein the coil assembly includes i) a pair of spring mechanisms attached to a connector block positioned between the pair of spring mechanisms, and ii) a pair of alignment mechanisms that align the spring mechanisms within the track, wherein the connector block is attached to the alignment mechanisms only through the spring mechanisms.
A method for controlling fore-aft vibrations in a seat assembly, comprising:
- positioning a connector block in a channel of a seat mounting frame;
- positioning a pair of spring mechanisms within the channel, wherein a first end of one spring mechanism is attached to one side of the connector block and a first end of the other spring mechanism is attached to the other side of the connector block;
- aligning the pair of spring mechanisms and the connector block within the channel of the seat mounting frame, wherein a second end of one spring mechanism is attached to a first alignment mechanism and a second end of the other spring mechanism is attached to a second alignment mechanism, and wherein the connector block is attached to the alignment mechanisms only through the spring mechanisms;
- attaching the connector block to a cross-member that moves in synchronization with the seat assembly on a parallel plane with the channel;
- and
- dampening the fore-aft vibrations via compensation of the pair of spring mechanisms.
