Definitions

  • the present invention refers to a system for adjusting and closing the visor of a crash helmet.
  • visors pivotally attached to the side walls of the helmet. These visors can assume a closed position in which they are lowered over the user's eyes and an open position in which they are raised above the helmet.
  • visors are difficult to combine with openable chin guards, that is to say chin guards that in turn can be lowered into a closed position and raised into an open position. For this reason precise adjustment of the visor proves complex.
  • some visors do not have sufficiently safe and reliable closing systems. In fact some closing systems fail to lock the visor perfectly in position when it is subject to the force of the airflow when the user of the helmet is on a moving vehicle.
  • the object of the present invention is to provide a system for adjusting and closing the visor of a crash helmet that is safe, practical, versatile and simple to make.
  • the system for adjusting and closing the visor of a crash helmet comprises two visor adjusting and closing devices disposed in the side walls of the outer shell of the helmet.
  • Each adjusting and closing device comprises a connecting rod hinged in the side part of the visor beneath the pin around which the visor turns.
  • the connecting rod is provided with a slot in which is located a pin fixed in the outer shell of the crash helmet.
  • the connecting rod can thus slide and be guided by the fixed pin of the outer shell.
  • Said slot provides seats in which the fixed pin of the outer shell can be received in snap engagement. In this manner the visor can assume different positions in accordance with the seat of the connecting rod in which the fixed pin is received.
  • the user can snap adjust the opening of the visor in the position most congenial to him/her.
  • the connecting rod acts as a lock for the chin guard, avoiding accidental lowering of the chin guard which could be dangerous.
  • a crash helmet indicated as a whole with reference numeral 1, comprises an outer shell 2 made, for example, of injection moulded ABS. Situated beneath the outer shell, in a substantially per se known manner, is an inner shell formed of foam polystyrene which is lined with a padding of polyurethane foam and fabric suited to come into contact with the user's head.
  • a chin guard 3 is pivotally attached to the outer shell 2, by means of pins 4 fixed to the two opposite sides of the outer shell 2, substantially level with the ears of the user wearing the crash helmet 1. In this manner, by pushing upward on the bottom part of the chin guard 3, the chin guard 3 is raised, turning around the axis of the pins 4.
  • An opening is defined between the bottom front edge of the outer shell 2 and the top front edge of the chin guard 3 to allow visibility for the user wearing the helmet.
  • the profile 5 of said opening is covered by a seal and the opening is covered by a visor 6 of transparent material, such as injection-moulded polycarbonate for example.
  • the visor 6 is pivotally attached to the chin guard 3 by means of two pins 7, disposed laterally, substantially level with the user's temples.
  • two protruding lunettes 8 are provided which face two flared parts 9 provided in the chin guard 3, so as to facilitate raising of the visor 6 by the user who can exert pressure on the protruding lunettes 8, positioning his fingers in the flared parts 9. In this manner, with an upward pressure exerted on the protruding lunettes 8, the visor 6 is raised, rotating around the axis of the pins 7.
  • a device 50 for adjusting and closing the visor 6 is provided in the gap between each side wall of the outer shell 2 of the crash helmet 1 and the respective inner side wallof the chin guard 3.
  • the adjusting and closing device 50 comprises a connecting rod 51 consisting of a substantially rectangular plate with rounded ends, made, for example, of acetal resin.
  • the connecting rod 51 is shown in view, also if it is arranged between the shell 2 and the chin guard 3, therefore it is covered by chin guard 3.
  • the connecting rod 51 is pivotally attached to the visor 6, by means of a pin 52 disposed beneath the pin 7 for raising/lowering the visor 6.
  • the pin 52 is short enough, so that it does not interfere with the chin guard 3.
  • the connecting rod 51 has a longitudinal slot 53 which receives a pin 60 fixed to the outer shell 2.
  • the pin 60 is short enough not to interfere with the chin guard 3.
  • the longitudinal slot 53 of the connecting rod 51 comprises three adjustment seats, 54, 55, 56 and a locking seat 57.
  • the pin 60 is locked in the locking seat 57, thus allowing a mechanical safety restraint which prevents accidental lowering of the chin guard.
  • the visor 6 When the chin guard 3 is lowered, the visor 6 remains locked in the closed position on the chin guard, thanks to locking due to the fact that the fixed pin 60 is received in the seat 54 of the connecting rod 51 and thanks to a further mechanical restraint conferred by hooking of the inner lip of the lunette 8 of the visor with the seal profile 5 of the chin guard 3.
