A roller skate boot including a lower outer boot adapted to encompass a foot of a skater, an upper boot cuff adapted to encompass a lower leg and ankle area of the skater; said upper boot cuff (9), in operation, being adapted to pivot forwardly and rearwardly in relation to said lower outer boot (6), and being pivotally connected thereto; said lower outer boot and said upper boot cuff each including a pair of substantially identical asymmetric apertures (17, 18) in the ankle area; said apertures being located on either side of the lower leg; said apertures being aligned between the lower outer boot (6) and the upper boot cuff (9) when the skater's foot and leg are in a normal upright position; said apertures being adapted to matingly engage a flexing regulator of substantially identical asymmeteric configuration as said apertures; said flexing regulator being constructed of an elastomeric material (37) which is deformable under a load; wherein, in operation, when a skater flexes a lower leg forwardly, said flexing regulator resists such flexure but permits said upper boot cuff to move forwardly; and when said skater relaxes said lower leg said flexing regulator causes said upper boot cuff to return to its normal upright position.

L'invention concerne une chaussure pour patin à roulettes, comprenant une partie de chaussure inférieure extérieure, conçue pour renfermer un pied d'un patineur, et un bracelet de chaussure (9), conçu pour maintenir une partie de jambe inférieure et une partie de cheville d'un patineur, ledit bracelet étant conçu de manière à fléchir vers l'avant et vers l'arrière, en relation avec la partie de chaussure inférieure (6) extérieure et relié pivotant à celle-ci. La partie de chaussure inférieure extérieure et le bracelet (9) de chaussure comprennent chacun une paire d'ouvertures (17, 18) identiques sensiblement asymétriques au niveau de la cheville, les ouvertures étant alignées entre la partie de chaussure inférieure (6) extérieure et le bracelet (9) de chaussure lorsque le pied et la jambe du patineur sont en position verticale normale. Les ouvertures sont conçues pour coopérer de manière exacte avec un régulateur de flexion, à configuration asymétrique sensiblement identique à celle des ouvertures, le régulateur de flexion étant constitué d'un matériau (37) élastique déformable sous une charge. Lorsqu'il patine, un patineur fléchit la partie inférieure de la jambe vers l'avant, le régulateur de flexion résistant à cette flexion mais permettant au bracelet de chaussure de fléchir vers l'avant. Lorsque le patineur relâche la jambe inférieure, le régulateur de flexion ramène le bracelet de chaussure à sa position verticale normale.
