Abstract: A pole handle comprising a wrist strap formed of a strap connected to an insert, a body oriented along a longitudinal axis, the body comprising an insert housing adapted to receive the insert, the insert housing being arranged in the upper portion of the body, such that the insert can be inserted into the housing along a direction substantially parallel to the longitudinal axis of the body, and a latching mechanism for retaining the insert in the insert housing, the unlatching of the latching mechanism being capable of being actuated directly by a displacement of the insert along the direction opposite that of insertion of the insert. The latching mechanism comprises a latch movable in relation to the body.

Abstract: A shock-absorbing helmet for sporting activities, e.g., including at least one damping layer covering a portion of the user's skull and an inner cap adapted to be inserted, at least partially, between the protective layer and the skull, the inner cap comprising at least one bladder. The inner volume of the bladder of the helmet defines an initial inner cap thickness, at least locally, in an initial customization configuration, and the helmet includes a mechanism for adjusting the inner volume of the bladder enabling, upon compression of the bladder, the discharge of a portion of the fluid contained in the bladder, the decrease in the inner volume of the bladder providing a localized reduction in the initial inner cap thickness in order to conform the inner cap to the morphology of the user's skull.
