Protective helmet, in particular motorcycle helmet, having a swivelable and removable chin part

Abstract

A protective helmet has a jet helmet part and a chin part which are releasably connected to each other by a coupling part. The chin part and the jet helmet part can be swiveled relative to each other by a swiveling mechanism between an integral helmet position and a jet helmet position. The coupling part includes a coupling element on the chin part and a second coupling element on the jet helmet part, which coupling elements engage to form a mutually releasable form-fit coupling. The swiveling mechanism actuates a locking mechanism where the locking mechanism includes a blocking slider and is designed such that, in the integral helmet position, the blocking slider blocks the first coupling element such that a decoupling of the coupling elements is prevented, and in the jet helmet position, the blocking of the first coupling element is released thereby enabling the coupling elements to be decoupled.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a schematic perspective illustration of a protective helmet having a jet helmet part and a chin part according to an exemplary embodiment;

(2) FIG. 2 shows a schematic perspective illustration of a chin part removed from the jet helmet part according to an exemplary embodiment; and

(3) FIGS. 3 to 8 show various schematic illustrations of a coupling part of a protective helmet described here according to a further exemplary embodiment.

DETAILED DESCRIPTION OF THE DRAWINGS

(4) In the exemplary embodiments and Figures, identical or identically acting components can each be provided with the same designations. The elements illustrated and their size relationships relative to one another are in principle not to be viewed as to scale. Instead, individual elements can be illustrated as exaggeratedly thick or over-dimensioned for better visualization and/or for better understanding.

(5) FIG. 1 shows a protective helmet 100 for a motorcyclist, comprising a jet helmet part 1 and a strap-shaped chin part 2. The chin part 2 is removably held via a coupling part 3 each fitted at the sides, approximately in an ear area of the jet helmet part 1, and can be swiveled upward and downward in arrow directions 4 instead of around a pivot as in a conventional rotary joint. The chin part 2 is shown in a lower, flipped-down integral helmet position and can be swiveled upward through about 90° into a jet helmet position.

(6) The protective helmet has a visor 5 made of transparent plastic, which is fitted to the jet helmet part 1 such that it can be swiveled in arrow directions 6 independently of the chin part 2. The visor 5 and the chin part 2 are illustrated as sectioned and with dashed outlines in the area of the coupling part 3, in order to illustrate their position on the protective helmet. The two coupling parts 3 of the helmet permit repeated removal and assembly of the chin part 2 with the jet helmet part 1. For the purpose of removal, a user pulls the chin part 2 off the jet helmet part 1 in an uncoupling direction 8. For assembly, the chin part 2 is pushed onto the jet helmet part 1 in a coupling direction 9.

(7) The state of the chin part 2 removed from the jet helmet part 1 is shown in FIG. 2, wherein the chin part 2 has been pulled off in the uncoupling direction 8 by the user following the opening of the coupling part 3.

(8) FIGS. 3 to 8 show various schematic illustrations of a coupling part 3 according to an exemplary embodiment. FIGS. 3, 4, 7 and 8 show a state of the coupling part 3 which in particular can occur in the jet helmet position. FIGS. 5 and 6, on the other hand, show a state of the coupling part 3 as occurs in particular in the integral helmet position.

(9) The coupling part 3 has a first coupling element 10, which is fixed to the chin part 2, and a second coupling element 11, which is fixed to the jet helmet part 1. The first coupling element 10 is formed as a one-piece plastic part and has a latching lug 16 which, for a releasable form-fitting coupling, can latch with a latching recess 17 in the second coupling element 11 which, in the exemplary embodiment shown, is likewise formed as a one-piece plastic part.

(10) The coupling part 3 is formed in such a way that, by means of the swiveling mechanism by means of which the chin part 2 is swiveled relative to the jet helmet part 1, a locking mechanism is activated. When the protective helmet 100 is changed from the jet helmet position to the integral helmet position, a blocking slider 7 is displaced by a locking cam 13 of a swivel arm 12, which is connected to the chin part 2 via a first joint 14 and to the first coupling element 10 via a second joint 15, in such a way that uncoupling of the coupling elements 10, 11 is blocked. In particular, the blocking slider 7 is displaced in such a way that an unhooking movement for releasing the latching of latching lug 16 and latching recess 17 is blocked by the arrangement of the blocking slider 7, since the blocking slider 7 is arranged behind the latching lug 16 in the direction of the unhooking movement. The blocking of the unhooking movement by the blocking slider 7 is illustrated in FIGS. 5 and 6.

(11) When the protective helmet 100 is changed from the integral helmet position to the jet helmet position, as illustrated in FIGS. 3 and 4, the swivel arm 12 is rotated in such a way that the blocking of the unhooking movement is released, since the locking cam 13 of the swivel arm 12 no longer displaces the blocking slider 7 behind the latching lug 16.

(12) The first coupling element 10 has a plurality of guide elements 19, which are formed as plastic hooks and by means of which the blocking slider 7 is displaceably supported. The blocking slider 7 is preferably formed as a one-piece plastic component.

(13) Furthermore, the first coupling element 10 has a slotted guide 18, in which a guide pin (not shown), which is fixed to the chin part 2, is guided. The guide pin is connected to the first coupling element 10 via a spring (not shown).

(14) FIGS. 7 and 8 show further perspective views of the coupling part 3 in the jet helmet position, wherein the first coupling element 10 is uncoupled from the second coupling element 11 in FIG. 8 following pressure on the latching lug 16, so that the chin part 2 is detached from the jet helmet part 1.

(15) The features described in the exemplary embodiments shown can also be combined with one another in accordance with the further exemplary embodiments. Alternatively or additionally, the exemplary embodiment shown in the Figures can have further features according to the embodiments of the general description.
