Patent number: 11957623Abstract: Protective eyewear such as goggles (12) are provided with a frame (14) lens (20) and a pair of tabs (30) protruding from a front (32) of the lens (20) at lateral positions, to receive tear off sheets. The frame (14) includes lateral attachment formations (28) that can engage complemental attachment formations (46) on removable roll holders (34,36). Each roll holder (34,36) includes an anchor formation (50) with a recess (54) in which one of the tabs (30) is receivable. The roll holders (34,36) can be fitted on the attachment formations (28) and tabs (30) to use a roll-off system, or can be removed to use a tear off system. The frame (14) preferably has pivoting outriggers (22) which include the attachment formations (28), so that the roll holders (34,36) are attached to the outriggers (22) and can pivot off the lens (20) with the outriggers (22).Type: GrantFiled: December 18, 2019Date of Patent: April 16, 2024Assignee: LEATT CORPORATIONInventors: Christopher James Leatt, Pieter André Keevy, Dominic Hamel

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: 20140038744Abstract: A golf club (10) is configured to dissipate kinetic energy during the impact when striking the golf ball, thereby to reduce the quantum of kinetic energy transferred from the golf club (10) to the ball and reducing the distance that the ball travels. The reduction in ball travel encourages the player to use more concentric muscle action at the moment of impact and thus to have better control over the impact. The golf club (10) includes a shaft (18) and a head (14) and the head (14) comprises a support structure (22) that is connected to the shaft (18), and an impact absorbent structure (16) that defines a face (46) of the golf club (10). The impact absorbent structure (16) includes a cushion (48), disposed between the face (46) and the support structure (22) and the cushion (48) is made of a shear thickening material.Type: ApplicationFiled: October 2, 2013Publication date: February 6, 2014Applicant: Leatt CorporationInventors: Christopher James Leatt, Willem Van Der Merwe, Robert Pilz

Patent number: 8562551Abstract: A neck brace (10) is disclosed which comprises two sections (12, 14) which are releasably connected to one another along a split line (18). The ring has upwardly facing surfaces (30, 76.1, 20.2) which limit tilting movement of a helmeted head in all directions. The brace further has a column (68, 70) which extends downwardly from the ring for transferring loads to the wearer's back on each side of the spine.Type: GrantFiled: August 9, 2011Date of Patent: October 22, 2013Assignee: Xceed Holdings CCInventor: Christopher James Leatt

Patent number: 8439042Abstract: A neck brace has two legs with a gap between them and the legs extend on either side of the wearer's neck and along the front of his torso. Shoulder protuberances, and chest protuberances extending laterally from each leg, are received underneath the shoulder straps of a harness, in the region of the wearer's shoulders and chest, respectively. A recess is defined on an underside of each leg between the shoulder protuberance and the chest protuberance to form a beam that is elevated above the wearer's chest. Each leg and its associated chest protuberance, define a channel in which one of the shoulder straps of the harness is receivable to be held captive.Type: GrantFiled: November 26, 2009Date of Patent: May 14, 2013Inventors: Christopher James Leatt, Mark Eric Hopkins

Publication number: 20110004980Abstract: A helmet (10) is provided, that has a first resilient shell (12), a support structure (16,18) inside the first shell to support the first shell on the wearer's head (14), a chin strap (20), to hold the helmet in position, a deformable layer (24) on the outside of the first shell and a tough outer shell (26) on the outside of the deformable layer. The deformable layer is of a material that absorbs energy when it is deformed and returns slowly to its original shape afterwards. The helmet includes a chin bar (34) with two opposing ends (36) that are displaceable relative to the outer shell, immediately inwardly of the outer shell. The outer profile of the helmet has a plurality of generally planar surfaces (28) and the helmet has a rear strap (38) that is attachable to the chin strap and that is configured to extend around the back of the wearer's head.Type: ApplicationFiled: October 13, 2006Publication date: January 13, 2011Applicant: LEATT BRACE HOLDINGS (PTY) LIMITEDInventors: Christopher James Leatt, Grant Leigh Nelson, Mark Eric Hopkins

Patent number: 7846117Abstract: Neck brace that inhibits excessive neck movement during impact, yet allows for a high degree of movement of the wearer's head during normal operation of the neck brace. May include impact surface(s) that limits movement of a helmet by contacting an underside of the helmet; bearing surface(s) configured for bearing on wearer; a structure between impact surface and bearing surface, sufficiently resilient to transfer impact loads of the helmet to the impact surface, to the wearer's body; wherein the impact surface is displaceable towards an adjacent part of the bearing surface and wherein the structure is configured to permit the displacement at rates slower than a predetermined rate of displacement and to resist the displacement if the rate of displacement exceeds the predetermined rate. May include a pivotal joint between the displaceable part and remainder of neck brace and impact brake element(s).Type: GrantFiled: July 17, 2007Date of Patent: December 7, 2010Assignee: Leatt Corp., Inc.Inventors: Christopher James Leatt, Grant Leigh Nelson, Mark Eric Hopkins
