Abstract
Abstract In preferred form a blower assembly for an automobile ventilation system including a blower motor, a blower fan connected to the motor for rotation, a resilient plastic member having a tubular end portion encircling and supporting the fan and a bellows portion connected at one end to the tubular end portion and attached at the other end to a wall of the automobile. Expansion and contraction of the bellows portion dampens axial and lateral vibrational movement of the blower motor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A blower assembly for an automobile ventilation system comprising an electric motor; a fan operably connected to said motor for rotation; a one piece motor mount of resilient plastic material for supporting said motor; said mount including a tubular end portion adapted to encircle said motor; an accordionwalled bellows portion of said mount integrally connected at one end to said tubular end portion; means connected to the other end of said bellows portion for attaching said mount to the automobile; said bellows portion including a plurality of surfaces which are serially integrally connected at adjacent edges and which alternately extend radially outwardly and radially inwardly with respect to the axis of the mount to form an expandable and contractable link between said tubular end portion and said attachment means and whereby vibrations of said motor are dampened by relative movement between said surfaces and the resultant bending of said connections between said surfaces.
Claim 2
Dependent Claim
153 words
A blower assembly for an automobile ventilation system comprising an electric motor; a fan operably connected to said motor for rotation; a one piece motor mount of resilient plastic material for supporting said motor; said mount including a tubular end portion adapted to encircle said motor; an accordionwalled bellows portion of said mount integrally connected at one end to said tubular end portion; means connected to the other end of said bellows portion for attaching said mount to the automobile; said bellows portion including a plurality of surfaces which are serially integrally connected at adjacent edges and which alternately extend radially outwardly and radially inwardly with respect to the axis of the mount to form an expandable and contractable link between said tubular end portion and said attachment means and whereby vibrations of said motor are dampened by relative movement between said surfaces and the resultant bending of said connections between said surfaces.
Claim 3
Dependent Claim
34 words
A blower assembly as set forth in claim 1 wherein outwardly projecting tabs on said motor coact with holes in said tubular end portion to axially position said motor in said tubular end portion.
Claim 4
Dependent Claim
53 words
The blower assembly as set forth in claim 1 wherein annular recesses in said connections between surfaces of said bellows portion reduce the thickness of said connection with respect to the thickness of adjacent surfaces and whereby said connections function as relatively flexible hinges to dampen movement between surfaces of such bellows portions.
Claim 5
Dependent Claim
148 words
A vibration dampening mount for the attachment of an electric motor to a structure comprising: a one-piece mounting member of resilient plastic material for supporting the motor in relation to the structure; said member having a tubular end portion adapted to encircle the motor; an accordion-walled bellows portion integrally connected at one end to said tubular end portion; means connected to the other end of said bellows portion for attaching said member to the automobile; said bellows portion including a plurality of surfaces which are serially integrally connected at adjacent edges and which alternately extend radially outward and radially inward with respect to the axis of said member to form an expandable and contractable link between said tubular end portion and said attachment means and whereby vibrations of the motor are dampened by relative movement between said surfaces and the resultant bending of said connections between said surfaces.
Claim 6
Dependent Claim
