Abstract
In accord with the present invention, a vehicle seat suspension apparatus is provided comprising: a seat suspension base; an isolator plate disposes above the base and adapted to support a vehicle seat; means for allowing reciprocating horizontal movement of the isolator plate relative to the base; an elongated guide mounted to one of either the base or the isolator and oriented along the travel path of the isolator; and a guide engaging member mounted to the other of the base or the isolator and engaging the guide to stabilize the isolator as it moves along its travel path.

A vehicle seat suspension apparatus comprising:
- a base;
- an isolator disposed above the base and adapted to support a vehicle seat;
- means for allowing reciprocating horizontal movement of the isolator relative to the base, including at least one pair of isolator rollers disposed along a horizontal axis and received within cooperating horizontally extending tracks;
- an elongated guide mounted to one of either the base or the isolator and oriented along the travel path of the isolator;
- and
- at least two spaced guide longitudinally aligned engaging members mounted to the other of the base or the isolator and engaging the guide at longitudinally spaced locations to stabilize the at least one pair of isolator rollers from horizontal movement perpendicular to the isolator travel path.
A vehicle seat suspension apparatus comprising:
- a base;
- an isolator disposed above the base and adapted to support a vehicle seat;
- means for allowing reciprocating horizontal movement of the isolator relative to the base, including at least one pair of isolator rollers disposed along a horizontal axis and received within cooperating horizontally extending tracks;
- an elongated guide mounted to one of either the base or the isolator and oriented along the travel path of the isolator, said guide comprising two spaced and longitudinally aligned channels, one disposed adjacent one end of the base or isolator and the other disposed adjacent the other end of the base or isolator ;
- and
- two spaced guide engaging members mounted to the other of the base or the isolator and engaging the guide at spaced locations to stabilize the at least one pair of isolator rollers from horizontal movement perpendicular to the isolator travel path, said two guide engaging members each comprising a guide roller with one guide roller disposed in each of said channels.
A vehicle seat suspension apparatus comprising:
- a base;
- an isolator disposed above the base and adapted to support a vehicle seat;
- means for allowing reciprocating horizontal movement of the isolator relative to the base, including at least one pair of isolator rollers disposed along a horizontal axis and received within cooperating horizontally extending tracks;
- an elongated guide rail mounted to one of either the base or the isolator and oriented along the travel path of the isolator;
- and
- at least two spaced guide engaging members mounted to the other of the base or the isolator and engaging the guide at spaced locations to stabilize the at least one pair of isolator rollers from horizontal movement perpendicular to the isolator travel path, said at least two guide engaging members comprising two pairs of guide rollers, and wherein one guide roller of each pair is disposed on each side of the rail.
