Abstract
Abstract A resilient boot assembly (10) of the type for containing a steering shaft (22) therein includes a tubular body portion (12) having a passageway (14) extending therethrough and first and second end portions (16,18). One end of the boot is adapted to attach to a steering gear housing (20). The assembly (10) is a unitary tubular member and includes at least one end having a resilient portion (24) and stiffened portions (26,28) at each end of the resilient portion for providing the flexible resilient portion (24) to roll up upon the body portion (12) to a retracted position to expose the connection between the steering shaft (22) and steering gear assembly and rolling down to an extended position to contain and perfect a seal with the steering gear housing (20).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A resilient boot assembly (10) of the type for containing a steering shaft (22) therein, said assembly (10) comprising; a tubular body portion (12) including a passageway (14) extending therethrough and first and second end portions (16,18), and attachment means for attaching at least one of said end portion (16) of said body portion (12) to a support structure (20), characterized by a said assembly (10) being a unitary tubular member and including roll-up means for rolling up and maintaining at least one of said end portions (16) upon said body portion (12) from an extended position defining a first axial length of said assembly (10) to a retracted seated position defining a second shorter axial length of said assembly (10) and rolling down said one end portion (16) to said extended position.
Claim 2
Dependent Claim
133 words
A resilient boot assembly (10) of the type for containing a steering shaft (22) therein, said assembly (10) comprising; a tubular body portion (12) including a passageway (14) extending therethrough and first and second end portions (16,18), and attachment means for attaching at least one of said end portion (16) of said body portion (12) to a support structure (20), characterized by a said assembly (10) being a unitary tubular member and including roll-up means for rolling up and maintaining at least one of said end portions (16) upon said body portion (12) from an extended position defining a first axial length of said assembly (10) to a retracted seated position defining a second shorter axial length of said assembly (10) and rolling down said one end portion (16) to said extended position.
Claim 3
Dependent Claim
82 words
An assembly as set forth in claim 1 further characterized by said rolling up means including an annular flexible portion (24) adjacent one of said end portions (16) and a stiffened portion (26,28) adjacent each end of said flexible portion (24), one of either .Iadd.of .Iaddend.said flexible portions (24) and said body portion (12) having a predetermined outer diameter and the other of said flexible portion (24) and body portion (12) having a predetermined inner diameter greater than said predetermined outer diameter.
Claim 4
Dependent Claim
