  • a helmet for use with riding a motorcycle, a snowmobile or the like receives a high wind pressure during running. For this reason, a helmet fittable user's head has been preferred in that a reduced weight is sensed by the user.
  • a pad or the like is inserted into an inner member to adjust the thickness of the inner member in accordance with the shape of user's head.
  • an inner member is provided with a belt, a string or the like so as to make it possible to adjust the position of the inner member in accordance with the shape of user's head by the belt, or the string.
  • a helmet has a shell which is made of plastic and is shaped into a fixed form.
  • the adjustable range is limited to a small extent.
  • human heads have different shapes. Accordingly, it is very difficult to fully fit the helmet on different shapes.
  • the present invention has overcome the above drawbacks and has an object of providing a helmet which can be adjusted so as to fit heads of different shapes, and assuredly give the user optimum sensation of fitting at all times.
  • the pump means is provided with an actuator portion on an underside of a lower edge portion of the shell so that the pump means is actuated from the lower side of the shell.
  • the thickness adjusting member is provided in portions corresponding to cheeks and a back of a head so that the inner cushion can come into contact with the cheeks and the back of the head.
  • the air is supplied and discharged to and from the thickness adjusting member so that the inward projection of the inner cushion is adjusted. Consequently, the helmet can surely be fitted on heads having different shapes.
  • the actuator member of the pump means is provided on the underside of the lower edge portion of the shell, the actuator member can be actuated with the helmet being put on.
  • the inward projection of the inner cushion can easily be adjusted.
  • the actuator portion of the pump means includes an air bag.
  • the pump means has a tube communicated with the thickness adjusting member, the tube having an opening at a forward end thereof for blowing the air in the thickness adjusting member, a plug movably attached in the opening for closing the opening.
  • the actuator portion of the pump means projects inward of the inner cushion. Then, the pump means can be grasped more easily. Also, the pump actuator can be deformed with an increased stroke. Accordingly, the pump means provides an increased pumping performance.
  • the actuator portion of the pump means is provided on a front underside portion of the lower edge portion of the shell, so that the pump actuator can stay in a space under the wearer's skin.
  • a helmet 10 includes a helmet shell 1, a shock absorber liner 2 for absorbing impact, an inner cushion 3 and an inner cover 9.
  • the helmet shell 1 is made of plastic such as fiber reinforced plastic (FRP).
  • the shock absorber liner 2 is made of foam plastic and provided on an inner surface of the helmet shell 1.
  • the inner cushion 3 is made of urethane foam and provided on an inner surface of the shock absorber liner 2.
  • the inner cover 9 covers the inner cushion 3.
  • a front opening portion 20 is covered with a shield 19.
  • the shield 19 is pivotally mounted on a pivot 19a attached on sides of the helmet shell 1, so that the shield 19 can be freely opened and closed. The position of the shield 19 can be changed from a closing state in which the shield 19 closes the opening portion 20 to an opening state in which the shield 19 is moved to an upper portion of the helmet shell 1 to open the opening portion 20 and vice versa.
  • Thickness adjusting members 4 are provided in portions facing cheeks and a back of a head 11 and between the shock absorber liner 2 and the inner cushion 3.
  • the thickness adjusting member 4 includes an air bag. As shown in Fig. 1, the thickness adjusting members 4 provided in the portions facing the cheeks have such width and height as to cover parts near the chin and ears. Also, the thickness adjusting member 4 provided in the portion facing the back of the head has the form of a narrow band.
  • the thickness adjusting members 4 are connected to one another by connecting members 41 so that the air can be supplied and discharged to and from all the thickness adjusting members 4 at the same time.
  • Pump means 90 are disposed on the underside of a lower edge portion of a shell 1.
  • the embodiment has three thickness adjusting members 4, specifically, one member to come into contact with head back, and two members to come into contact with head sides.
  • the three members are connected to one another by means of connecting members 41 and connectors 44 for joining the connecting members 41.
  • One connecting member 41 which is positioned at a forward end is provided with a breather 30 at an intermediate portion thereof.
  • the breather 30 functions as a connector.
  • One end of the pump means 90 is connected to the connecting member 41 having the breather 30 by way of a connector 44.
  • the pump means 90 has a nonreturn valve 98 at the other end.
  • the pump means 90 is provided on lower edge portions of the shell 1 and a shock absorber liner 3 in a front portion of a helmet 10.
  • the pump means 90 includes an inner skin 92, an outer skin 91 made of flexible material, and an air bag 93 provided inside of the inner and outer skins 92 and 91.
  • the outer skin 91 is fixedly attached to the shell 1 by adhesive.
  • the breather 30 has a pair of cylinders 31 and a cylinder 39.
  • the connecting members 41 are fitted on the cylinders 31.
  • the cylinder 39 is projected in perpendicular to an axis of the cylinders 31.
  • a valve rod 36 is axially movably inserted in the cylinder 39.
  • a sleeve 32 is provided between the cylinder 39 and the valve rod 36.
  • a flange 34 of the valve rod 36 is pressed against a gland packing 35 attached on an end of the sleeve 32 by a spring 33 provided inside the breather 30, so that the cylinder 39 is sealed.
  • a trim member 49 is attached to a lower end portion of the shell 1.
  • a through hole 15 is formed in the trim member 49 and the shell 1.
  • a recess 30a is formed in the shock absorber liner 2.
  • the recess 30a is formed in a portion corresponding to the through hole 15.
  • a breather casing 47 is placed in the through hole 15.
  • a pusher 46 (actuator member) is movably provided in the breather casing 47. A forward end of the pusher 46 comes into contact with a forward end of the valve rod 36 of the breather 30. All the outer surfaces of the trim member 49, the breather casing 47 and the pusher 46 are arranged so as to be substantially flush with an outer surface of the shell 1.
  • the pusher 46 constituting an air discharge portion can be provided in the vicinity of the lower end portion of the shell 1. Therefore, the pusher 46 gives a smaller influence to the appearance of the shell 1.
  • the air is supplied into the thickness adjusting members 4 through the breather 30 from the air bag 94 by pressing the outer skin 91 of the pump means 90 in a direction of an arrow shown in Fig. 7 so as to deform inward. Releasing the pressure to the outer skin 91 causes the outer skin 91 to return to its original shape due to its resilient force. At this time, the air is supplied from the nonreturn valve 93 into the air bag 93.
  • the valve rod 36 made in contact with the forward end of the pusher 46 is pushed in against the biasing force of the spring 33, so that spaces occur between the flange 34 and the gland packing 35, and between the sleeve 32 and the valve rod 36. Then, the air is discharged through the spaces from she cylinder 31, and the thickness adjusting members 4.
  • Fig. 6 shows a pump means 95.
  • the pump means 95 is provided on the underside of lower edge portions of the shell 1 and the shock absorber liner 3 in a front or side of the helmet 1.
  • the pump means 95 includes an inner skin 97 made of fabric, an outer skin 96 made of flexible material such as soft vinyl chloride, and an air bag 94. An inner end of the pump means 95 is projected inward from the inner cover 9.
  • the outer skin 96 is fixedly attached to the shell 1 by adhesive. Further, the outer skin 96 and the inner skin 97 are seamed together.
  • the pump means 95 is projected inward. Accordingly, the pump means 95 can be grasped more easily. Also, an increased deformation can be given to the pump means 95, in other words, the pump means can be deformed with an increased stroke. Accordingly, the pump means 95 provides an increased pumping performance. Further, as shown in phantom lines in Fig. 7, the pump means 95 can be deformed by taking hold of a lower surface portion of the outer skin 96 and an inner end portion of the inner skin 97. In this case, the air bag 94 can be deformed more easily.
  • the air is discharged out of the thickness adjusting members 4.
  • the outer skin 91 shown in Fig. 3, or the outer skin 96 shown in Fig. 6 and 7 is repeatedly pressed so that the air is supplied to the thickness adjusting members 4.
  • the inner cushion 3 is pressed inward as shown in phantom lines in Figs. 2 and 3 so as to come into pressing contact with the cheeks and the back of the head 11.
  • the helmet 10 can be made to fit head of any shape.
  • pump means is not necessary to expose to the outside. Pump means may be exposed to the inside of a helmet. Also, it is allowable that a plug is attached to an forward opening of a tube which is communicated with thickness adjusting members so that the air can be blown into the thickness adjusting members with the mouth. Thickness adjusting members may disposed in other portions of a helmet.
  • a thickness adjusting member is provided between a shock absorber liner and an inner cushion.
