Abstract
Abstract An emergency ring of elastic material for a vehicle wheel having a one-piece deep bed rim comprises a one-piece annular support body, which via support rings are supported exclusively on the rim bed of the wheel and is spaced apart from at least one side wall region or of a pneumatic tire. Reinforcement inlays are disposed radially such that there is only relatively little compressible elastic material within the reinforcement inlays. High security against rotation of the emergency ring relative to the rim is thereby assured. Moreover, the emergency ring is easily mounted and provides great security against a tire being thrown off, even when cornering with tires with low air pressure.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
126 words
An emergency ring for a vehicle wheel which is composed of a one-piece rim with a rim bed and a pneumatic tire, comprising a one-piece annular elastic body having annular reinforcement inlays and a radially outside portion on which, in an emergency, a radially inside portion of the pneumatic tire remote from tire tread comes to rest, an axially outer side face, axially an inner side face, and a radially inside portion oriented toward the rim bed, wherein the radially inside portion of the emergency ring is supported by at least a part of a surface thereof on the rim bed, and at least one of the axially outer and inner side faces is spaced apart from an adjacent side wall region of the pneumatic tire.
Claim 2
Dependent Claim
126 words
An emergency ring for a vehicle wheel which is composed of a one-piece rim with a rim bed and a pneumatic tire, comprising a one-piece annular elastic body having annular reinforcement inlays and a radially outside portion on which, in an emergency, a radially inside portion of the pneumatic tire remote from tire tread comes to rest, an axially outer side face, axially an inner side face, and a radially inside portion oriented toward the rim bed, wherein the radially inside portion of the emergency ring is supported by at least a part of a surface thereof on the rim bed, and at least one of the axially outer and inner side faces is spaced apart from an adjacent side wall region of the pneumatic tire.
Claim 3
Dependent Claim
41 words
The emergency ring of claim 1, in which the rim is a one-piece deep bed rim, and the radially inside of the emergency ring is supported by at least a portion of a surface thereof in the bed of the rim.
Claim 4
Dependent Claim
28 words
The emergency ring of claim 1, wherein the radially inside portion of the emergency ring has two annular bearing regions for supporting the ring on the rim bed.
Claim 5
Dependent Claim
42 words
The emergency ring of claim 1, wherein the axially outer and inner side faces are curved, and the at least one of the axially inner and outer side faces has a contour similar to a contour of the adjacent side wall region.
Claim 6
Dependent Claim
38 words
The emergency ring of claim 1, wherein a spacing of the radially outer side face from an outer hump region of the rim is no greater than a width of an outer tire bead of the pneumatic tire.
Claim 7
Dependent Claim
37 words
The emergency ring of claim 1, wherein a width of the emergency ring in a mounted, unloaded condition is substantially equal to a rim opening width reduced by from 0.5 to 2 times the tire bead thickness.
Claim 8
Dependent Claim
38 words
The emergency ring of claim 6, wherein a spacing of the radially outer side face from an outer hump region of the rim is no greater than a width of an outer tire bead of the pneumatic tire.
Claim 9
Dependent Claim
26 words
The emergency ring of claim 1, wherein a height of the mounted, unloaded emergency ring in a mounted, unloaded condition is about half a tire height.
Claim 10
Dependent Claim
38 words
The emergency ring of claim 8, wherein a spacing of the radially outer side face from an outer hump region of the rim is no greater than a width of an outer tire bead of the pneumatic tire.
Claim 11
Dependent Claim
37 words
The emergency ring of claim 9, wherein a width of the emergency ring in a mounted, unloaded condition is substantially equal to a rim opening width reduced by from 0.5 to 2 times the tire bead thickness.
Claim 12
Dependent Claim
22 words
The emergency ring of claim 1, wherein a diameter of the reinforcement inlays is only slightly greater than a wheel flange diameter.
Claim 13
Dependent Claim
38 words
The emergency ring of claim 11, wherein a spacing of the radially outer side face from an outer hump region of the rim is no greater than a width of an outer tire bead of the pneumatic tire.
Claim 14
Dependent Claim
37 words
The emergency ring of claim 12, wherein a width of the emergency ring in a mounted, unloaded condition is substantially equal to a rim opening width reduced by from 0.5 to 2 times the tire bead thickness.
Claim 15
Dependent Claim
26 words
The emergency ring of claim 13, wherein a height of the mounted, unloaded emergency ring in a mounted, unloaded condition is about half a tire height.
Claim 16
Dependent Claim
33 words
The emergency ring of claim 1, wherein the center of gravity of the emergency ring in a mounted, unloaded condition is located in an axial direction near a center plane of the rim.
Claim 17
Dependent Claim
31 words
The emergency ring of claim 1, wherein at least one of the emergency ring on an inside thereof and the bed are configured to generate positive engagement in the circumferential direction.
Claim 18
Dependent Claim
33 words
The emergency ring of claim 1, wherein the bed of the rim is configured, at least intermittently in the circumferential direction, to generate positive engagement in an axial direction with the emergency ring.
Claim 19
Dependent Claim
27 words
The emergency ring of claim 1, wherein the emergency ring on an outside thereof has a plurality of circumferentially distributed recesses extending transversely to a circumferential direction.
