Publication number: 20230404199Abstract: A helmet has an outer shell, an impact absorbing liner inside the outer shell to receive loads from the outer shell and an inner liner disposed inside the impact absorbing liner, with the inner liner configured to slide relative to the impact absorbing liner. The inner liner defines a number of apertures and a deflector inside each aperture. Each deflector has a body that is connectable to the impact absorbing liner; a peripheral border that is connectable to the aperture in which it is received; and a number of deformable spokes extending between the body and the border.Type: ApplicationFiled: September 6, 2023Publication date: December 21, 2023Inventors: Pieter André KEEVY, Jörn Peter STEFFENS

Patent number: 11234483Abstract: An item of footwear such as a boot (10) includes a stiff lower part (12) that extends around part of a wearer's foot, a stiff upper part (16) that extends around the wearer's lower leg, and one or more limit elements (66,72,80,88) that extend between the lower part (12) and the upper part (16). The lower part (12) and upper part (16) are movable relative to each other when the ankle moves and the relative movement is inhibited selectively by the limit elements (66,72,80,88). The limit elements (66,72,80,88) are displaceable between a free condition in which the lower part (12) and the upper part (16) are movable relative to each other, and lock condition in which the relative movement between the lower part (12) and the upper part (16) is inhibited.Type: GrantFiled: December 21, 2016Date of Patent: February 1, 2022Assignee: LEATT CORPORATIONInventors: Christopher James Leatt, Carel Sias Meyer, Cornelis Uys De Jongh, Jörn Peter Steffens

Publication number: 20160128860Abstract: A knee brace (10) according to the invention includes an upper leg formation (12), a lower leg formation (14) and a hinge mechanism (16) that is disposed entirely on the lateral side of the knee. The knee brace (10) has pressure formations (20, 24,62, 28) pressing on three pressure points: on the lateral aspect of the wearer's upper leg, on the lateral aspect of the wearer's lower leg, and against the knee complex on the medial aspect of the distal extremity of the femur. The three pressure formations are connected to one another by a stiff structure (18, 16) which includes the hinge mechanism (16).Type: ApplicationFiled: May 26, 2014Publication date: May 12, 2016Inventors: Christopher James LEATT, Cornelis Uys DE JONGH, Pieter Andre KEEVY, Jörn Peter STEFFENS
