Claim 6

A shock absorbing mount as set forth in claim 1 in which said elastomeric sleeve has a plurality of radially extending slits formed in its said one end.

Claim 7

A shock absorbing mount as set forth in claim 1 in which a seal is disposed around said piston between said head and said one end of said cylinder.

Claim 8

A shock absorbing mount as set forth in claim 1 in which an end cap is mounted on said cylinder opposite said one end thereof, and said end cap and piston have mounting means mounted thereon.

Claim 9

A shock absorbing mount for an automotive vehicle, comprising a cylinder having an opening at one of its ends and closEd at its opposite end by an end cap, a piston carried in said cylinder and projecting outwardly through said opening, said piston having a head slidably carried against the inner walls of said cylinder, a bag carried within said cylinder, said bag having an end wall generally normal to the axis of said cylinder and connected to the bag side walls, means retaining said bag side walls in sealing engagement with the inner walls of said cylinder, an air valve in said end cap in open communication with said bag, and elastomeric sleeve slidably carried in said cylinder with one of its ends engaging said piston head, a slide interposed between and engaging said bag and member, and means on said slide engageable with the opposite end of said sleeve whereby said sleeve is moved outwardly and scrubs against the inner wall of said cylinder when said piston is forced inwardly into said cylinder.

Claim 10

A shock absorbing mount for an automotive vehicle, comprising a cylinder having an opening at one of its ends and closEd at its opposite end by an end cap, a piston carried in said cylinder and projecting outwardly through said opening, said piston having a head slidably carried against the inner walls of said cylinder, a bag carried within said cylinder, said bag having an end wall generally normal to the axis of said cylinder and connected to the bag side walls, means retaining said bag side walls in sealing engagement with the inner walls of said cylinder, an air valve in said end cap in open communication with said bag, and elastomeric sleeve slidably carried in said cylinder with one of its ends engaging said piston head, a slide interposed between and engaging said bag and member, and means on said slide engageable with the opposite end of said sleeve whereby said sleeve is moved outwardly and scrubs against the inner wall of said cylinder when said piston is forced inwardly into said cylinder.

Claim 11

A shock absorbing mount for an automotive vehicle comprising a cylinder, a piston carried in said cylinder and projecting outwardly from one end thereof, said piston having a head slidably engaging the inner walls of said cylinder, an inflatable bag carried within said cylinder, an elastomeric sleeve slidably carried in said cylinder with one of its ends in engagement with said piston head, a slide interposed between and in engagement with said bag and the opposite end of said sleeve, said slide having a generally cylindrical base section slidably carried against the inner walls of said cylinder and disposed in abutting engagement with said bag and a generally conical section projecting outwardly from said base section, the apex of said conical section being received in an opening in said sleeve to cause said sleeve to move outwardly and scrub against the inner walls of said cylinder when said piston is forced inwardly into said cylinder.

Claim 12

A shock absorbing mount for an automotive vehicle comprising a cylinder, a piston carried in said cylinder and projecting outwardly from one end thereof, said piston having a head slidably engaging the inner walls of said cylinder, an inflatable bag carried within said cylinder, an elastomeric sleeve slidably carried in said cylinder with one of its ends in engagement with said piston head, a slide interposed between and in engagement with said bag and the opposite end of said sleeve, said slide having a generally cylindrical base section slidably carried against the inner walls of said cylinder and disposed in abutting engagement with said bag and a generally conical section projecting outwardly from said base section, the apex of said conical section being received in an opening in said sleeve to cause said sleeve to move outwardly and scrub against the inner walls of said cylinder when said piston is forced inwardly into said cylinder.

Claim 13

A shock absorbing mount as set forth in claim 9 in which said opening in said sleeve extends axially therethrough.

Claim 14

A shock absorbing mount for an automotive vehicle, comprising a cylinder having an opening at one of its ends and closed at its opposite end by an end cap, a piston carried in said cylinder and projecting outwardly through said opening, said piston having a head slidably carried against the inner walls of said cylinder, a bag carried within said cylinder, said bag having an end wall generally normal to the axis of said cylinder and connected to the bag side walls, means retaining said bag side walls in sealing engagement with the inner walls of said cylinder, an air valve in said end cap in open communication with said bag, an elastomeric sleeve slidably carried in said cylinder with one of its ends in engagement with said piston head, a slide having a generally cylindrical base section slidably carried against the inner walls of said cylinder and disposed in abutting engagement with said bag end wall and a generally conical section projecting outwardly from said base section, the apex of said conical section being received in the opposite end of said sleeve to cause said sleeve to move outwardly and scrub against the inner walls of said cylinder when said piston is forced inwardly into said cylinder, a shaft projecting outwardly from the apex of said conical section and slidably carried in said sleeve and piston, a retaining member mounted on said shaft in said piston, and a spring carried on said shaft and bearing against said piston and retaining member to urge said slide into engagement with said sleeve.

Claim 15

A shock absorbing mount for an automotive vehicle, comprising a cylinder having an opening at one of its ends and closed at its opposite end by an end cap, a piston carried in said cylinder and projecting outwardly through said opening, said piston having a head slidably carried against the inner walls of said cylinder, a bag carried within said cylinder, said bag having an end wall generally normal to the axis of said cylinder and connected to the bag side walls, means retaining said bag side walls in sealing engagement with the inner walls of said cylinder, an air valve in said end cap in open communication with said bag, an elastomeric sleeve slidably carried in said cylinder with one of its ends in engagement with said piston head, a slide having a generally cylindrical base section slidably carried against the inner walls of said cylinder and disposed in abutting engagement with said bag end wall and a generally conical section projecting outwardly from said base section, the apex of said conical section being received in the opposite end of said sleeve to cause said sleeve to move outwardly and scrub against the inner walls of said cylinder when said piston is forced inwardly into said cylinder, a shaft projecting outwardly from the apex of said conical section and slidably carried in said sleeve and piston, a retaining member mounted on said shaft in said piston, and a spring carried on said shaft and bearing against said piston and retaining member to urge said slide into engagement with said sleeve.
