An airbag compartment enclosure assembly is disclosed, including a compartment containing an uninflated airbag and a closure device fixed proximate an opening of the compartment. The closure device has an open position allowing expansion of the airbag through the opening and a closed position retaining the uninflated airbag. The closure device includes a first flap extending from a first edge of the opening and a second flap extending from a second, opposing edge of the opening. The first and second flaps are folded over one another in the closed position.

Embodiments of wood-type club heads comprising one or more components are described herein. The wood-type club head comprises a first, metallic component, and a second, non-metallic component. The first component comprises the load bearing structure that forms the striking face, and portions of the crown, the heel, the toe, and the sole. The second component comprises a lightweight structure that wraps around the first component to form portions of the crown, the heel, the toe, and the sole. The first component comprises mass pads and receives removable weights to adjust the weight properties of the club head. The two-component design allows for additional discretionary mass redistribution to improve center of gravity location and moment of inertia.

Training apparatus comprises exercise equipment mounted to a side surface or a roof of a land vehicle or for mounting to a surface such as a wall of a building or ship. The exercise equipment comprises a support structure which is attached to the surface or roof. In some embodiments the support structure is maneuverable by pivoting with respect to the surface or roof, whilst remaining attached thereto, between a stowed condition and an exercising condition.

An adjustment tool for adjusting a height of an upper bar of a gymnastics uneven bars apparatus. The adjustment tool is comprised of a shaft having a handle at one end and a horizontally-facing hook at an opposed end. In another embodiment, the hook faces upwards. The hook is sized and shaped to receive the upper bar, and is formed with a pair of outwardly flaring lips to allow the hook to be guided onto the bar without causing damage thereto. The handle is typically formed into a hook resembling that of a cane. A shaft length in an adjustable embodiment is comprised of two or more telescoping members mating with one another to establish and maintain desired shaft length.

A mouthguard according to an embodiment of the present disclosure includes a pair of spaced lateral bite wings, a conduit defining an air channel extending between forward portions of the lateral bite wings, and a lip shield member and/or a flange disposed around and extending radially outward with respect to a forward end of the conduit. The conduit is tapered inward from its forward end toward its rearward end, and defines an incisor engaging surface proximate the rearward end of the conduit, and a lip engaging surface between the incisor engaging surface and the forward end of the conduit.
