Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
A wheel rim having a base and two seats for tiRe beads, each seat being extended by a flange, and provided with a mounting well adjacent one flange and a removable annular device filling the well, characterized by the fact that: a. the mounting well is contiguous one of the flanges and forms an extension thereof, b. the annular filling device is a stretchable flexible lining having a radial profile such that the lining applies itself against the walls of the mounting well and forms the seat for a tire bead and an extension of this seat to the rim base, and that at least the bead seat and its extension which are formed by the lining are compressible without variation in the total volume of the lining.
Claim 2
Dependent Claim
128 words
A wheel rim having a base and two seats for tiRe beads, each seat being extended by a flange, and provided with a mounting well adjacent one flange and a removable annular device filling the well, characterized by the fact that: a. the mounting well is contiguous one of the flanges and forms an extension thereof, b. the annular filling device is a stretchable flexible lining having a radial profile such that the lining applies itself against the walls of the mounting well and forms the seat for a tire bead and an extension of this seat to the rim base, and that at least the bead seat and its extension which are formed by the lining are compressible without variation in the total volume of the lining.
Claim 3
Dependent Claim
34 words
The wheel rim according to claim 1, characterized by the fact that the mounting well has a radial profile with an axial width increasing from the bottom of the well towards the bead seat.
Claim 4
Dependent Claim
25 words
The wheel rim according to claim 1, characterized by the fact that the mounting well has means for preventing the lining from turning on itself.
Claim 5
Dependent Claim
31 words
The wheel rim according to claim 3, characterized by the fact that the said means are formed of circumferential striations on the wall of the well in contact with the lining.
Claim 6
Dependent Claim
43 words
The wheel rim according to claim 1, characterized by the fact that the lining has a cross section in the shape of an L lying on its side, and that the well has an additional rib near the rim flange adjacent the well.
Claim 7
Dependent Claim
35 words
The wheel rim according to claim 1, characterized by the fact that the lining has a cross section such that its center of gravity is located radially and axially below the bead of the tire.
Claim 8
Dependent Claim
62 words
The wheel rim according to claim 1, characterized by the fact that the lining has a larger developed circumferential length than the developed length of the base of the bead of the tire and, after mounting and inflation of the tire, forms a circumferential protuberance in the zone located between the bead of the tire and the opposite wall of the well.
Claim 9
Dependent Claim
24 words
The wheel rim according to claim 1, characterized by the fact that the lining forms a sealing joint between the tire and the rim.
Claim 10
Dependent Claim
21 words
The wheel rim according to claim 1, characterized by the fact that the lining consists of a single piece of rubber.
