An attachment system for a helmet, the system having a buckle and a stud. The stud has an engaging portion and the buckle extends along a longitudinal axis and has first and second slots for receiving an adjustable strap and a rim defining a housing having an opening for receiving the engaging portion, the housing opening extending in a direction that is transversal to the longitudinal axis of the buckle. The rim is configured to allow sliding engagement with the engaging portion in a direction that is transversal to the longitudinal axis of the buckle between a first position wherein a section of the rim retains the engaging portion in the rim housing for locking the buckle into the stud and a second position wherein the engaging portion is no longer retained in the rim housing for releasing the buckle from the stud.

A fastener having two strap ends connected by an elastomeric member is described. The elastomeric member has sufficient elasticity to allow a user to increase the distance of separation between the two strap ends by applying a separation force, while providing enough tension to return the two strap ends to close proximity when the user releases the separation force. The elastomeric member may also have an adjustable elasticity to accommodate different applications with different load forces. The two strap ends may each be attached to two connectors.

A buckle includes a female part having a housing and an engaging portion provided at an inner surface of the housing, and a male part including a base and an inserted portion to be inserted into the housing of the female part. The inserted portion includes a base end coupled to the base, a free end opposite to the base end, and an engaged portion to be engaged with the engaging portion. When a force is applied to the male part for pulling the male part out of the housing, the engaged portion has a contact surface that is in contact with the engaging portion. Relative to a first center point at the center of the base end in the thickness direction of the inserted portion, a second center point at the center of the contact surface in said thickness direction is positioned downward.

A wireless quick release buckle. The release buckle includes a male plug fastened into a female socket creating a locked buckle assembly. A wireless signal from a remote control is used to quickly release the male plug from the female socket. The male plug further includes springs, a lock rod and riveted hinges attached to plug arms; the hinges are secured to allow the plug arms to simultaneously move inward. The male plug further includes an actuation mechanism which includes a small motor and a receiver to receive a signal from the remote control which activates the actuation mechanism to thereby quickly release the buckle.

Two-stage clasp mechanisms, and related systems and methods, are disclosed herein. In some embodiments, the clasp mechanism includes a first housing portion, a second housing portion configured to connect to the first housing portion, and a locking mechanism configured to secure the first and second housing portions together. The locking mechanism can include a first striker carried by the second housing portion, a second striker movably carried by the first housing portion, and a blocking component movably carried by the second housing portion. The second striker is moveable along a first direction between an engaged position and a disengaged position with the first striker. The blocking component is movable along a second direction at an angle with respect to the first direction between a first position that prevents the first striker from moving and a second position that allows the second striker to move.

A buckle assembly includes a buckle member that is configured to removably connect to a reciprocal buckle member. A retaining guard couples to the buckle member. The retaining guard is configured to reduce a potential of pinching as the buckle member connects to and disconnects from the reciprocal buckle member by providing a barrier where the buckle member and reciprocal buckle member connect.

A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component, a second magnetic component and a clearance structure. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component. The clearance structure allows the second locking portion to slide an offsetting position for preventing the separation of the male buckling component and the female buckling component after engagement of the first locking portion and the second locking portion.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.
