Definitions

• TITLE Support device for the passenger of a motorcycle
• the present invention relates to a device for holding handles for the passenger of a motorcycle, the device being placed in front of the driver.
• the motorcycles provided with a seat for the transport of a passenger but having no grab handle.
• the passenger in this case puts his arms around the driver and the belt to maintain himself or else puts his hands on the tank.
• the passenger considerably annoys the driver, who must bear his weight during braking
• the tilt of the passenger forward helps him to counter the force which pushes him back during the phases of accelerations, and he can lean on the tank during the braking phases to avoid putting his weight on the driver.
• the passenger is excessively leaning forward. He finds himself very close to the driver, which affects his comfort and the driver's freedom of movement.
• a previous invention presented in Japanese utility application 61-171678 proposes a motorcycle equipped with grab handles for the passenger fixed between the latter and the driver.
• the passenger grabbing this type of handles has his arms very folded so that his arm and forearm form, at the elbow, an angle of approximately ninety degrees. This type of position is ill-suited to allow the passenger to stay on the motorcycle without excessive effort.
• the device, placed behind the driver forces the passenger to position himself behind the motorcycle, which amplifies the phenomenon of offset from the center of gravity of the conventional handle systems mentioned above and makes it all the more dangerous. .
• Another invention patent registered in France under the number 8901412 proposes a motorcycle comprising handles for the passenger fixed to the motorcycle in front of the driver's seat.
• This system has the advantage of offering a stable, comfortable and secure position for the passenger grabbing the grab handles and of guaranteeing the driver a good balance of the motorcycle.
• the aforementioned patent has the major drawback of proposing grab handles for the passenger permanently attached to the motorcycle.
• the fasteners on the motorcycle of the handles proposed in this patent must withstand very large forces due to the leverage effect caused by the passenger to maintain itself during strong accelerations or powerful braking.
• the embodiments of this invention provide a device attached to the fuel tank or to the frame of the motorcycle by welding or bolting.
• An object of the present invention is, in particular, to provide a device which can be fitted in an easily removable manner to a large majority of motorcycles with grab handles for the passenger placed in front of the driver.
• the invention also aims to preserve the advantages of a handle system at the front of the driver by overcoming the disadvantages of existing systems.
• the invention provides a holding device for the passenger of a motorcycle comprising two holding elements each having a fixing zone which cooperates releasably with a tank mat, or any other equivalent device occupying the same position. , through at least two releasable attachment points, and a portion forming a grip and support handle for the passenger which is located in alignment with the releasable attachment points of the attachment zone.
• the device according to the invention While retaining the advantages provided by a system of handles for the passenger in front of the driver, the device according to the invention has the advantage of fitting without difficulty and a posteriori a large majority of motorcycles.
• Another advantage of the present invention lies in the great simplicity of the device which allows occasional mounting on the motorcycle with very easy installation and removal.
• the removable device thus allows the owner to find the original appearance of his motorcycle at all times and to preserve its aesthetics.
• the present invention has the advantage of allowing certain motorcycle models to be more versatile because they are better suited to the duo.
• the device in fact makes it possible to equip, for example, motorcycles not having one, a grab handle for the passenger.
• Figure 1 is a side view of a driver and his passenger in the driving position on a motorcycle equipped with the device of the present invention.
• Figure 2 shows a side view of a holding element of the device.
• Figure 3 shows a top view of the device according to a first embodiment of the present invention.
• Figures 4 and 5 show respectively a top view and a side view of the device according to a second embodiment of the present invention.
• Figure 6 is a partial view, in section, taken along the line VI-VI of Figure 7 and showing an alternative embodiment applicable to flexible tank belts.
• Figure 7 is the top view of Figure 6.
• Figure 1 shows a driver in the driving position on a motorcycle equipped with the device of the present invention. It carries a passenger who has his arms around his waist grabbing the holding elements of the device (10 and 10 ').
• the drawing illustrates that the passenger has a position similar to that of the driver and that the device allows him to stay at a sufficient distance to avoid hampering his movements: the device allows them to benefit from a comfortable and reassuring position.
• the drawing shows that the device being small and having its gripping and support parts for the passenger inclined forward is of no apparent danger to the driver in the event of a fall, in particular frontal impact, and leaves it free to move.
• Figure 2 shows a side view of a holding element (10 or 10 ') of the device with, schematically, a passenger arm gripping the grip and support part (12 or 12').
• This drawing explains why the fixing points (13 and 14 respectively 13 'and 14') of the fixing zones (11 respectively 11 ') can be reduced so that quick couplers, in particular, can be used to fix the device on the tank.
• Mass transfers during the use of a motorcycle are very important during strong acceleration and during strong braking.
• the movements of the passenger therefore take place mainly in the median plane of the motorcycle; the forces due to the latter's efforts to maintain themselves are exerted in the extension of his arms.
• the parts (12 and 12 ') of the device forming a grip and support handle for the passenger are in the same alignment as the fixing points (13 and 14 respectively 13' and 14 ') of the parts (11 and 11'); the axes (31 and 31 ') passing through the fixing points (13 and 14 respectively 13' and 14 ') of the parts (11 and 11') of the device are substantially symmetrical and parallel to the median plane (30) of the motorcycle (see FIG. 3).
• Figure 2 also shows that the angle ⁇ formed by the axis passing through the fixings (13 and 14 respectively 13 'and 14') of the parts (11 or 11 ') of the device and the axis passing through the parts (12 or 12 ') forming grip and support handles is a closed angle so as to obtain an angle ⁇ formed between the parts (12 and 12') forming grip handle and the passenger arms of substantially 90 °.
