Abstract: This protective helmet comprises a rigid or semi-rigid external shell comprising a plurality of rigid or semi-rigid flaps joined together and a compressively deformable internal liner acting as a shock absorber, the latter also comprising several elements associated with said flaps. At least some of the flaps that constitute the external shell are capable of moving relative to each other at their respective means of connection and the elements that constitute the internal liner associated with the flaps in question are designed so that they retract inside the volume defined by the helmet during relative displacement of the corresponding flaps.

Abstract: Outer protective shell is made from a sheet or plate of rigid polymer. It has a plurality of partial incisions suitable for defining substantially jointed motifs, for imparting to the said shell a degree of overall flexibility, and local rigidity, and also breathability.

Abstract: This is a system of one or more handles for an item of kitchen equipment for cooking on a cooker or a hob. A number of items can be stacked together. Each handle has at least one stud (125) and/or at least one housing (131) for keeping the superposed items in the form of a stack, the housing and/or the stud therefore being designed, respectively, to receive another stud and/or to be received in another, complementary housing. Each handle further comprises a locking projection (162) and a receiving zone (162) designed, respectively, to be engaged with another receiving zone provided on another handle and to receive the engagement of another locking projection provided on this handle intended for the other item.
