DETAILED DESCRIPTION

(12) The description of two forms of preferred embodiments of the invention is made below, referring to the references in the figures.

(13) The invention relates to a protective helmet which comprises three elements: an inner component (1), an intermediate component (2) and an outer base component (3). These elements are retractable by means of pressure, each one being folded inside the next one.

(14) A description of the invention based on the previously mentioned figures is made below.

(15) FIGS. 1 to 5 show a first embodiment of the present invention.

(16) FIG. 1 shows a perspective view of the helmet in its deployed position, where its three constitutive components (1, 2, 3) may be distinguished. The male (5) and female (4) guide elements are also shown. Also, as shown in FIG. 1, at least one through hole (11) is provided in the inner component.

(17) FIG. 2 shows a perspective view of the helmet in its retracted position, where its three constitutive components (1, 2, 3) may be distinguished. The male (5) and female (4) guide elements are also shown.

(18) FIG. 3 shows a plan view of the helmet in its retracted position.

(19) FIGS. 4a and 4b show cross-section views along to the cross-sectional plane A-A of the helmet in its deployed and retracted positions respectively.

(20) FIGS. 5a and 5b show cross-section views along to the cross-sectional plane B-B of the helmet in its deployed and retracted positions respectively in the zone of the guide elements, such that the operations of the guide system may be seen in detail.

(21) The material used for manufacturing the helmet in this embodiment is a polymer suitable for absorbing impacts, with the possibility of incorporating an outer layer of another material with a function which is esthetic and also distributes stress in the event of an impact.

(22) FIGS. 6 to 9 show a second embodiment of the present invention.

(23) FIG. 6 shows a perspective view of the helmet in its deployed position, where its three constitutive components (1, 2, 3) may be distinguished. As shown in FIG. 6, the inner component (1) has an elliptical shape and is provided with a plurality of through holes (11) formed along the major axis of the inner component.

(24) FIG. 7 shows a perspective view of the helmet in its retracted position, where its three constitutive components (1, 2, 3) may be distinguished.

(25) FIG. 8 shows a plan view of the helmet in its retracted position.
