A flexible bolster for installation between two load-carrying members in a vehicle suspension. The bolster comprises a block of rubber or rubber-like elastomer sandwiched between two end plates. The block of rubber preferably has molded thereon a plurality of metal washers or plates oriented parallel to each other and the end plates. A bore extends axially through the end plates and block of rubber. A rebound control restraint is disposed in the bore. The restraint comprise a length of cable having retainers swaged to its opposite ends. Each retainer has an enlarged part or assembly which bears against the outer side of one of the end plates. The restraint acts to limit the extent to which the end plates separate when the bolster is under tension and thereby controls rebound. The restraint is free so as not to absorb compression or shear forces applied to the bolster.

A flexible bolster for transmitting forces in substantially all directions when installed between load-carrying members in a vehicle suspension, comprising two opposing end plates each for connection to one of said load-carrying members and which are substantially parallel to each other when said bolster is in its unloaded condition, a cylindrical block of rubber or resilient elastomer sandwiched between said end plates and attached thereto by curing in contact therewith so as to resist being separated therefrom, a continuous bore extending axially through said end plates and said block, and a rebound control restraint extending through said bore and comprising a length of cable within said bore having secured to one end a first retainer means having a generally spherical convex surface seated in a mating concave surface formed in the outer side of one of said end plates at one end of said bore and having secured to the other end of said length of cable a second retainer means in engagement with the outer side of the other end plate at the opposite end of said bore, said rebound control restraint being under tension when controlling rebound but not subject to absorbing compression forces applied to said bolster and allowing said end plates to shift laterally with respect to each other and wherein said second retainer means comprises a cylindrical screw which projects from said other end plate and has an integrally formed socket on its distal end within the adjacent end of said bore into which an end of said length of cable is swaged, a nut screwed down on said cylindrical screw into engagement either with said outer side of the adjacent end plate or a washer disposed between said nut and said adjacent end plate.
