Seat suspension system

Claim 2

A seat suspension system comprising: a. a base member and a mounting member positioned in spaced apart relation; b. a vehicle seat mounted on said mounting member; c. an inflatable resilient member between and engaging said base member and said mounting member thereby separating same; d. a plurality of spaced generally parallel elongate guides fixed on and extending from one of said base member and mounting member; e. a like plurality of cooperating members extending from the other of said base member and mounting member and engageable with said respective guides for linear movement therealong whereby said base member and mounting member are arranged for guided movement toward and away from each other; f. said guides and the respective posts received therein being arranged in a generally triangular pattern with a guide and post on each side of the inflatable resilient member and a guide and post positioned adjacent the center of a rear portion of the seat suspension system; g. said inflatable resilient member being positioned forward of the side guides and posts; and h. means associated with said inflatable resilient member for controlling the inflation thereof whereby relative movement between said base member and mounting member is pneumatically cushioned.

Claim 3

A seat suspension system as set forth in claim 1 wherein: a. said guides are each tubular members; b. said cooperating members are posts and are received within respective guides; c. said guides each have a bearing therein engageable by said respective post received therein; and d. said bearings and said respective post received therein have a minimum clearance between whereby relative lateral movement between said base member and mounting member is substantially restrained.

Claim 4

A seat suspension system as set forth in claim 2 wherein said inflatable resilient member has one end fixed relative to said base member and the other end fixed relative to the mounting member whereby said base and mounting members are substantially restrained.

Claim 5

A seat suspension system as set forth in claim 3 wherein said inflation controlling means include: a. a source of air under pressure; b. conduit means communicating said inflatable resilient member with said source of air under pressure; and c. adjustable valve means in said conduit means for selectively adjusting the amount of inflation of said inflatable resilient member.

Claim 6

A seat suspension system as set forth in claim 4 including a skirt member depending from the mounting member having the seat mounted thereon to at least partially enclose said inflatable resilient member.

Claim 7

A seat suspension system comprising: a. a base member and a mounting member positioned in spaced apart relation, said base member being adapted to be fixedly mounted in a mobile vehicle; b. a plurality of spaced tubular guides extending from one of the fixedly mounted base member and mounting member toward the other; c. a like plurality of generally parallel posts extending from the other of the mounting member and base member and arranged for each post to be received within a respective guide; d. an inflatable resilient member between and secured to said base member and mounting member thereby separating same; e. means communicating with said inflatable resilient member for controlling the inflation thereof whereby relative movement between said base member and a seat mounted on the mounting member is pneumatically cushioned; f. a source of air under pressure adapted to be mounted on the mobile vehicle; g. conduit means communicating said source of air under pressure with said inflatable resilient member; h. adjustable valve means in said conduit means for selectively adjusting the amount of pressure within said inflatable resilient member, said adjustable vale means being positioned within reach of a person on the seat; i. a bearing within each of said guides and engageable by said respective post received therein, each Of said bearings and said respective post received therein having a minimum clearance therebetween whereby relative lateral movement between said base member and mounting member is substantially restrained; j. a skirt member depending from the base member having the seat mounted thereon to at least partially enclose said inflatable resilient member; k. said guides and the respective posts received therein being arranged in a generally triangular pattern with a guide and post on each side of the inflatable resilient member and a guide and post positioned adjacent the center of a rear portion of the seat suspension system; l. said inflatable resilient member being positioned forward of the side guides and posts; and m. said adjustable valve means of said inflation controlling means including an adjustable supply valve for inflating said inflatable resilient member and an adjustable relief valve for allowing escape of excess pressure from said inflatable resilient member thereby adjusting the amount of inflation therein.

Claim 8

A seat suspension system comprising: a. a base member and a mounting member positioned in spaced apart relation, said base member being adapted to be fixedly mounted in a mobile vehicle; b. a plurality of spaced tubular guides extending from one of the fixedly mounted base member and mounting member toward the other; c. a like plurality of generally parallel posts extending from the other of the mounting member and base member and arranged for each post to be received within a respective guide; d. an inflatable resilient member between and secured to said base member and mounting member thereby separating same; e. means communicating with said inflatable resilient member for controlling the inflation thereof whereby relative movement between said base member and a seat mounted on the mounting member is pneumatically cushioned; f. a source of air under pressure adapted to be mounted on the mobile vehicle; g. conduit means communicating said source of air under pressure with said inflatable resilient member; h. adjustable valve means in said conduit means for selectively adjusting the amount of pressure within said inflatable resilient member, said adjustable vale means being positioned within reach of a person on the seat; i. a bearing within each of said guides and engageable by said respective post received therein, each Of said bearings and said respective post received therein having a minimum clearance therebetween whereby relative lateral movement between said base member and mounting member is substantially restrained; j. a skirt member depending from the base member having the seat mounted thereon to at least partially enclose said inflatable resilient member; k. said guides and the respective posts received therein being arranged in a generally triangular pattern with a guide and post on each side of the inflatable resilient member and a guide and post positioned adjacent the center of a rear portion of the seat suspension system; l. said inflatable resilient member being positioned forward of the side guides and posts; and m. said adjustable valve means of said inflation controlling means including an adjustable supply valve for inflating said inflatable resilient member and an adjustable relief valve for allowing escape of excess pressure from said inflatable resilient member thereby adjusting the amount of inflation therein.
