Abstract
Abstract A one-piece elastic support having an outer loop-like main body portion secured to the vehicle body with a tether or strap projecting in a cantilever manner from the loop into the central opening for supporting a portion of the exhaust system from the lower end of the strap, the lower end of the strap having a tab or cam that projects beyond the lower end of the loop for contact with it to prevent undue deflection of the strap, the engagement of the tab effecting a stiffer or more rigid suspension thereafter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A suspension device for an exhaust pipe of a motor vehicle comprising a one-piece flexible mounting support member having a loop type body portion with a central opening, an elastic tether portion depending in a cantilever manner from the body portion into the central opening for a swinging movement with respect to the body portion, the body portion having a hole therein at one end adapted to receive a vehicle support member therethrough, and the tether portion having a hole therein adapted to receive therethrough a portion of the exhaust pipe to provide an elastically soft suspension of the exhaust pipe from the vehicle, the tether portion being freely swingible through the central opening in either direction, and including a protuberance extending from one end a distance sufficient to overlap the body portion during swinging movement of the tether portion in one direction to thereby engage the tether portion against the body portion to resist further swinging movement of the tether portion in the one direction.
Claim 2
Dependent Claim
166 words
A suspension device for an exhaust pipe of a motor vehicle comprising a one-piece flexible mounting support member having a loop type body portion with a central opening, an elastic tether portion depending in a cantilever manner from the body portion into the central opening for a swinging movement with respect to the body portion, the body portion having a hole therein at one end adapted to receive a vehicle support member therethrough, and the tether portion having a hole therein adapted to receive therethrough a portion of the exhaust pipe to provide an elastically soft suspension of the exhaust pipe from the vehicle, the tether portion being freely swingible through the central opening in either direction, and including a protuberance extending from one end a distance sufficient to overlap the body portion during swinging movement of the tether portion in one direction to thereby engage the tether portion against the body portion to resist further swinging movement of the tether portion in the one direction.
Claim 3
Dependent Claim
55 words
A device as in claim 1, wherein the body portion is less elastic than the tether portion providing a first soft linear rate of suspension of the exhaust pipe from the free-standing tether and a second harder linear rate of suspension upon engagement of the protruding portion of the tether portion with the body portion.
Claim 4
Dependent Claim
29 words
A device as in claim 1, the body portion and tether portion being one continuous homogeneous member of a rubber-like consistency providing elasticity to all portions of the member.
Claim 5
Dependent Claim
75 words
A device as in claim 1, the flexible member depending from the vehicle support in an essentially vertical manner, the tether portion constituting a tongue-like strap depending freely downwardly from the body portion towards but spaced from the lower end of the loop-like body portion, the protuberance constituting an abutment-like tab engaging the lower end of the body portion and preventing swinging movement of the strap past the body portion and through the central opening.
Claim 6
Dependent Claim
26 words
A device as in claim 2, the body portion being constructed with reinforcement means therein providing less elasticity to the body portion than the tether portion.
