Description

OBJECT OF THE INVENTION

[0001] The present invention, a system for controlling a sun visor for a helmet, relates to a system that is incorporated into a safety helmet for motorised vehicles, in particular motorbike or motor racing helmets, said system comprising an extraction mechanism with a control device, integrated into the mechanism, which permits said visor to be positioned at different heights in a lower stowed position in order to adjust the use position according to the preferences of the user and so that it is better suited to their physiognomy.

[0002] The field of application of the present invention falls within the industrial sector dedicated to the manufacture of motorbike helmets and the like, particularly focusing on the area of extraction mechanisms of sun visors.

BACKGROUND OF THE INVENTION

[0003] As is known, the incorporation of extractable sun visors into motorbike helmets and the like is widely known. A problem is that most mechanisms which permit said visor to be placed from an upper stowed position superior, located in the upper portion of the helmet above the front opening thereof, to a lower stowed position, with other intermediate use positions, where the visor is positioned so as to cover most of the opening such that it is placed in front of the face of the user, coinciding with the user's eyes in order to protect them from the incident sun rays or harsh weather conditions. Said lower stowed position is fixed, whereby said position may not always be the ideal position for each user, given that there are a number of different physiognomies which mean that the position of the eyes with respect to the front opening of the helmet may vary substantially from one user to the next.

[0004] It would therefore be desirable for each user to be able to adapt the use position of the visor according to physiognomy, and also according to the user's preferences or needs.

[0005] Therefore, the objective of the present invention is a system for controlling a sun visor which resolves said drawbacks by means of the development of an extraction mechanism which includes means for being able to vary the use position in a quick and easy manner, offering at least several alternatives for the user to be able to choose the one that is the most suited in each case.

[0006] Moreover, and as a reference to the current state of the art, it should be pointed out that the applicant at least is unaware of the existence of a system for controlling the sun visor for a helmet such as the one of the present invention.

DESCRIPTION OF THE INVENTION

[0007] The object of the present invention is a system for controlling a sun visor for a helmet according to claim 1. Said system is, specifically, a system in which the visor is attached at both sides to a helmet through an extraction mechanism which permits the visor to be moved between two stowed positions, a lower stowed position and an upper stowed position, covering the front opening of the helmet, comprising a control device on at least one of both sides of said extraction mechanism with a rotary knob in order to vary the lower height of the visor when it is in the lower stowed position.

[0008] More specifically, the system for controlling a sun visor for a helmet, preferably a motorbike helmet, a motor racing helmet or the like, has an extraction mechanism which permits the visor to be moved from a stowed position, in which it is concealed in the upper portion of the helmet above the front opening thereof, to a use position, in which it moves downwards to a position covering the upper portion of said opening in front of the user's face, coinciding with the user's eyes; it is distinguished by having, integrated into said extraction mechanism of the visor, a control device for positioning said visor in the use position at different heights, permitting the user to choose the preferred position which best suits their physiognomy.

[0009] To that end, and more specifically, said device is essentially configured from a rotary knob which, linked to a support having radial lugs having a different length, is incorporated into the cover in which there rests the latch securing the visor in the lower use position, intercalated between the lower stop of said cover and the mentioned latch, such that, according to the position in which said support is placed upon making the knob rotate, the length of the lug which is positioned in the upper portion acts as a stop for the latch in a more or less elevated position, causing the lower use position of the visor to be, in turn, more or less elevated.

[0010] Preferably, the support having lugs has three lugs of three different lengths arranged radially, whereby the visor can preferably be controlled in three use positions in the lower stowed position.

[0011] Preferably, the rotary knob in which the support having radial lugs is coupled externally has, that is, on the face that is visible, marks indicative, for example by means of numbering, of the different lengths of each of the lugs of the support, in order to indicate the different use position heights of the visor to be chosen, according to the position in which the knob is rotated.

PREFERRED EMBODIMENT OF THE INVENTION

[0013] An embodiment of the invention object of the present application is described below in view of the mentioned figures.

[0014] Thus, as can be observed in said figures, the system for controlling a sun visor (1) is of the type coupled to the helmet (2) through an extraction mechanism (3) which attaches it, on both sides, to same with the possibility of movement from an upper stowed position, in which it is concealed above the front opening of the helmet (2), to a lower use position, as shown in Figure 1, in which it covers the upper portion of said opening, with the particular feature of having, integrated into at least one of both sides of said extraction mechanism (3), a control device (4) which permits the user to position the visor (1) in the lower use position at different heights, without needing to use tools or remove the visor (1) or the extraction mechanism (3), but rather by simply moving a rotary knob (40).

[0015] Thus, in the preferred embodiment, said control device (4) is coupled to both sides of the extraction mechanism (3) and essentially comprises a rotary knob (40) which, linked to a support (41) provided with several radial lugs (42) having a different length such that upon making the knob (40) rotate, it also rotates said support (41), is incorporated into the extraction mechanism (3) in the lower portion, such that the lug (42) of the support (41) which is located in the upper portion acts as a stop, limiting the downward movement of the visor (1) to the lower use position in said mechanism (3).

[0016] For that purpose, the extraction mechanism (3), as seen in Figure 2, comprises a cover (30) having an approximately triangular configuration which is fixed integrally to the helmet (2), and a latch (31) which is attached at one end to the visor (1) and at the opposite end rotates coupled to the cover (30) in an enclosure (32) thereof, between the upper and lower positions limited by a respective upper partition (33) and a respective lower partition (34) of said cover (30); it preferably has in the lower portion, next to an opening of the aforesaid lower partition (34), a circular coupling (35) suitable for the fixing of the support (41) having radial lugs (42) of the control device (4).

[0017] Preferably, the latch (31) has in the lower portion a slot (36) in which there fits the lug (42) of the support (41) which is positioned in the upper portion when said latch (31) is in the lower use position. According to the length of said lug (42), the latch (31) will be more or less elevated, and accordingly, the visor (1) will adopt a lower use position more or less elevated. Preferably, the support (41) has three radial lugs (42) having a different length.

[0018] Likewise, the rotary knob (40) is coupled to the support (41) having radial lugs (42) through a rod (43) provided therein, being pressed into the central gap (44) of said support (41), fitting such that both elements rotate integrally with one another as a result of projections (45) provided for that purpose. The rotary knob (40) externally has marks (46) indicative of the different lengths of each of the lugs (42) of the support (41). Preferably, said marks (46) are in relief, serving at the same time to secure the knob and achieve its rotation.

[0019] Lastly, it should be pointed out that the control device (4) further comprises a frame (47) formed by a part fitting into a complementary recess of the helmet (2) into which the rotary knob (40) in turn fits, such that it does not represent an element protruding from the surface of the helmet.
