- the three types of chin ventilator constituent members 53 to 55 can be built in the head protecting body 2 .
- the chin ventilator mechanism 51 has the chin air supply path 121 and the pair of left and right chin exhaust paths 122 a and 122 b (to be described later).
- the chin air supply path 121 is sequentially comprised of
- the notches 84 of the shutter member 54 and the notches 75 of the air supply port forming member 55 from its start point (i.e., the air inlet port to the chin air supply path 121 ) to its end point (i.e., the air outlet port from the chin air supply path 121 ).
- the start point of the chin air supply path 121 is formed by the outer surfaces of those halves of the pair of left and right air supply/exhaust holes 111 a and 111 b , which are on the central longitudinal section line 40 side, of the outer shell 11 . These outer surfaces form the air inlet port to the chin air supply path 121 .
- outer air i.e., external air
- those halves of the air supply/exhaust holes 111 a and 111 b which are on the central longitudinal section line 40 side, serve as the air supply hole portions of the chin air supply path 121 .
- the external air flows from the notches 84 and 75 described in the item 4) to near the lower end of the inner surface of the shield plate 4 through the two gaps described in the item 2) and one gap described in the item 3), as shown in FIGS. 2 and 3.
- the external air can be introduced into the head protecting body 2 through the chin air supply path 121 .
- the external air is straightened by the straightening air supply paths 65 a to 67 a and 65 b to 67 b while it flows upward in the three gaps described in the items 2) and 3).
- the external air flowing to near the lower end of the inner surface of the shield plate 4 i.e., above the substantially central portion of the impact-on-the-chin-and-cheek absorbing liner 23 and above the breath guard 114 ) shifts upward along the inner surface of the shield plate 4 to reach near the upper end of the inner surface of the shield plate 4 .
- the external air flow can effectively prevent the shield plate 4 from being fogged by the breath exhaled by the wearer.
- the chin air supply path 121 can be blocked by operating the shutter member 54 . More specifically, when the engaged projection 87 of the shutter member 54 engages with the central one of the three engaging recesses of the waved spring 79 , the projections (i.e., the blocking portions) 85 of the shutter member 54 block the notches (i.e., air outlet ports) 75 of the air supply port forming member 55 .
- the wearer When the wearer holds the tap 89 of the shutter member 54 and moves the shutter member 54 to the left or right so the engaged projection 87 of the shutter member 54 engages with another engaging recess, other than the central one, of the waved spring 79 , the projections 85 of the shutter member 54 are displaced from the notches 75 of the air supply port forming member 55 to substantially overlie on the projections 76 . Hence, the air outlet ports 75 of the air supply port forming member 55 are opened. Therefore, when the wearer operates the shutter member 54 to engage the engaged projection 87 with the central engaging recess of the waved spring 79 , the chin air supply path 121 can be blocked so air supply through it can be stopped.
- the pair of left and right chin exhaust paths 122 a and 122 b are symmetrical (i.e., axi-symmetrical) about the central longitudinal section line 40 shown in FIGS. 5A and 5B as the axis of symmetry.
- the left chin exhaust path 122 a will be described in detail with reference to FIGS. 3, 4, 5 A and 5 B, and a detailed description on the right chin exhaust path 122 b will be omitted.
- the start point of the left chin exhaust path 122 a is formed by the inner surface of the exhaust port 46 of the left half of the impact absorbing liner 23 . This inner surface forms the air inlet port to the left chin exhaust path 122 a .
- the end point of the left chin exhaust path 122 a is formed of the outer surface of that half of the air supply/exhaust hole 111 a , which is opposite to the central longitudinal section line 40 side, of the outer shell 11 . This outer surface forms the air outlet port from the left exhaust path 122 a .
- the space described in the item 2) forms an exhaust gap.
- the external air flows relatively from the substantially front surface into the other half of the air supply/exhaust hole 111 a described in the item 3). Simultaneously, the external air abutting against near the central portion of the chin region of the outer surface of the outer shell 11 is deflected horizontally outward (i.e., from the central longitudinal section line 40 side to the left opposite to it) along the outer surface of the outer shell 11 , and flows backward.
- the external air flowing relatively from the substantially front surface into the other half of the air supply/exhaust hole 111 a described in the item 3) is blocked by the front surface 103 of the exhaust path recess 93 a in the left half of the impact-on-the-chin-and-cheek absorbing liner 23 (in this case, the slant angle ⁇ 1 of this front surface 103 functions or a negative pressure is produced as will be described later), and is deflected horizontally outward.
- Air in the impact-on-the-chin-and-cheek absorbing liner 23 , below the breath guard 114 and near the exhaust hole 46 described in the item 1) (i.e., internal air including breath exhaled by the wearer and near the intermediate position in the vertical direction of the chin region of the impact absorbing liner 23 ) flows into this exhaust hole 46 , reaches the other half of the air supply/exhaust hole 111 a described in the item 3) through the space described in the item 2), and flows out of the outer shell 11 from this other half.
- that half of the air supply/exhaust hole 111 a which is opposite to the central longitudinal section line 40 side, serves as the exhaust hole portion of the chin exhaust path 122 a . Since air in the head protecting body 2 can be exhausted to the outside through the chin exhaust path 122 a , the shield plate 4 can be prevented further effectively from being fogged by the breath exhaled by the wearer or the like.
- the head ventilator mechanism 52 has one or a plurality of (in the embodiment shown in FIGS. 2 and 6, a pair of left and right) ventilation grooves 131 extending substantially semicircularly from the front end to the rear end (in other words, from the front head region to the nape region through the top head region and back head region) through the substantially central portion, in the right-to-left direction, of the inner surface (i.e., inner circumferential surface) of the impact-on-the-head absorbing liner 21 .
- the ventilation grooves 131 serve as head air paths, and are wide from their start points to near the front head region and narrow from there to the top head region.

Abstract
A helmet with an air supply/exhaust hole serving as a hole to be shared by an air supply hole portion for an air supply path for introducing air outside an outer shell into a head protecting body, and an exhaust hole portion for an exhaust path for exhausting air in the head protecting body to an outside of the outer shell. According to this helmet, a predetermined region in the head protecting body can be ventilated well. The air supply hole portion for the air supply path and the exhaust hole portion for the exhaust path can be formed in the outer shell easily. An outer shell with a high strength can be obtained easily. Design limitations on the outer shell can be reduced.
Description
- The present invention relates to a helmet having a head protecting body with an outer shell, in which an air supply path for introducing air outside the outer shell into the head protecting body is formed in the head protecting body, and an exhaust path for exhausting air in the head protecting body outside the outer shell is formed in the head protecting body apart from the air supply path.
- Conventionally, as a helmet to be worn by the head of a helmet wearer (to be referred to as a “wearer” hereinafter) such as the rider of a motor cycle, a full-face-type helmet is known. Usually, the cap-shaped head protecting body of such a full-face-type helmet has a chin ventilator mechanism under a window opening formed to oppose the face of the wearer. The chin ventilator mechanism has a chin air supply path extending from an air supply port or air supply notch formed in the chin region (i.e., a region opposing the chin of the wearer) of the outer shell. In addition to the chin air supply path, a breath guard is attached to the head protecting body between the mouth of the wearer and a shield plate in order to prevent the shield plate from being fogged by the breath exhaled by the wearer.
- In such a conventional helmet, outer air is introduced, near the lower end of the inner surface of the shield plate, into the head protecting body through the chin air supply path. The introduced outer air is let to flow upward along the inner surface of the shield plate, and the breath guard prevents the breath exhaled by the wearer from being directly directed toward the shield plate, thereby preventing fogging of the shield plate.
- In this conventional helmet, when the humidity is very high due to a rainfall, the shield plate is inevitably fogged due to the breath exhaled by the wearer, and anti-fogging of the shield plate cannot be performed well. Therefore, as a countermeasure, in the conventional helmet, a pair of right and left exhaust holes may be formed in the chin region of an impact absorbing liner. A pair of right and left exhaust holes may be formed in a corresponding chin region of an outer liner, and a pair of right and left chin exhaust paths may be formed to extend from the liner-side exhaust holes to the outer-shell-side exhaust holes.
- In the conventional helmet with the above arrangement, the air supply hole for the chin air supply path must be formed at substantially the central portion of the chin region of the outer shell, and the pair of right and left air supply holes for the pair of right and left chin air supply paths must be formed on the right and left sides of the chin region of the outer shell. This requires a complicated process of forming the air supply hole and exhaust holes in the outer shell, and it is cumbersome and time-consuming to obtain an outer shell with a high strength. Also, the outer shell has a large design limitation.
- The present invention is directed to correcting the drawbacks described above of the conventional helmet effectively with a comparatively simple arrangement.
- It is, therefore, the main object of the present invention to provide a helmet in which an air supply path for introducing air outside an outer shell into a head protecting body and an exhaust path for exhausting air in the head protecting body outside the outer shell are formed in the head protecting body apart from and adjacent to each other, so that air is supplied to and exhausted from a predetermined region in the head protecting body simultaneously, thereby ventilating the predetermined area well.
- It is another object of the present invention to provide a helmet in which since an air supply hole for an air supply path and an exhaust hole for an exhaust path need not be separately formed in an outer shell independently of each other, the process of forming both an air supply hole portion for an air supply path and an exhaust hole portion for an exhaust path in the outer shell can be comparatively simple, an outer shell with a high strength can be obtained comparatively easily, and design limitation on the outer shell can be made comparatively small.
- It is still another object of the present invention to provide a helmet in which an air supply path can have a comparatively simple structure and outer air can flow in the air supply path in a good state.
- It is still another object of the present invention to provide a helmet in which an air exhaust path can have a comparatively simple structure.
- It is still another object of the present invention to provide a helmet in which since air is supplied to and exhausted from the chin region in the head protecting body simultaneously, the chin region can be ventilated well, so that even when the humidity is very high due to a rainfall, the shield plate can be effectively prevented from being fogged by the breath exhaled by the wearer.

The central portion of the front surface of the membermain body 71 projects outward (i.e., toward the front surface), thus forming a projectingsurface 73. The inner surface (i.e., the rear surface) of the projectingsurface 73 forms a recess. The upper half of the front surface of the membermain body 71 is thinner than the lower half thereof and thus forms a thin-walled portion 71 a. The screw insertion holes 72 a and 72 b are formed near the left and right ends of the lower half of the front surface of the membermain body 71. - As shown in FIGS. 3 and 4, an inner air supply
port forming portion 74 is formed at the upper end of the thin-walled portions 71 a of the membermain body 71 of the air supplyport forming member 55 to extend substantially horizontally along the upper end of the thin-walled portions 71 a, such that it protrudes almost backward to be flexed slightly obliquely upward in the backward direction. The inner air supplyport forming portion 74 extends forward to form a projectingridge 74 a. As the inner air supplyport forming portion 74 has a comb-like shape with a large number ofnotches 75 formed in its rear end side, a large number ofprojections 76 are formed between thenotches 75. Thenotches 75 form a plurality of (e.g., three) inner air supply ports on each of the right and left sides. Of the large number ofprojections 76, a pair of left and rightleft projections central projection 76 a has engaging holes (not shown), formed in their rear surfaces, to fit on the pair of left and rightengaged studs path forming member 53. - As shown in FIG. 4, a substantially U-shaped hanging
portion 77 is integrally formed at the central portion of the membermain body 71 of the air supplyport forming member 55, and accordingly anopening 78 is formed between the membermain body 71 and hangingportion 77. Also, a wavedspring 79 is integrally formed on the rear surface of the hangingportion 77 across theopening 78 substantially horizontally, and accordingly theopening 78 is halved into an upper andlower openings ridge 80 is formed on the periphery of theupper opening 78 a along its upper side and left and right sides. A projectingridge 81 with a groove (not shown) substantially at its center is integrally formed along the lower end of the hangingportion 77 such that it protrudes backward. Thespring 79 has a substantially L-shaped longitudinal section and forms astep 79 a on its outer surface (i.e., front surface). - As shown in FIGS. 3 and 4, the
shutter member 54 has a membermain body 82 extending to be curved (a curve protruding outward) substantially arcuately in the horizontal direction substantially along the membermain body 71 of the air supplyport forming member 55. An opening/closing shutter portion 83 is provided to the upper end of membermain body 82 of theshutter member 54 to extend substantially horizontally along the upper end of the membermain body 82, such that it protrudes almost backward to be flexed slightly obliquely upward in the backward direction. As the opening/closing shutter portion 83 has a comb-like shape and a large number ofnotches 84 are formed near its rear end to correspond to thenotches 75 of the air supplyport forming member 55, a large number ofprojections 85 are formed between thenotches 84. Thenotches 84 form a plurality of (e.g., five) air supply ports, and theprojections 85 form a plurality of (e.g., six) blocking portions. - As shown in FIG. 4, a substantially square hanging
portion 86, which extends downward, is integrally formed at the substantially central portion of the lower end of the membermain body 82 of theshutter member 54. An engagedstud 87 is integrally formed at the substantially central portion of the lower end of the hangingportion 86. A connectingportion 88 with a substantially L-shaped longitudinal section is integrally formed on the hangingportion 86 near the lower end of its front surface. The connectingportion 88 extends substantially horizontally from the hangingportion 86 such that it protrudes almost forward to be flexed slightly obliquely downward in the forward direction, and then substantially vertically such that it protrudes almost downward to be flexed slightly obliquely forward in the downward direction. - A
tap 89 is integrally formed on the lower end of the connectingportion 88 of theshutter member 54, as shown in FIG. 4, to extend obliquely forward and downward from this lower end. Thetap 89 has anotch 90 at its distal end so the wearer can hold thetap 89 with his fingers easily. Astud 91 is integrally formed on the lower surface of thetap 89, when necessary, so thetap 89 of theshutter member 54 can be slid easily along the outer surface of theouter shell 11. - The three types of chin ventilator
constituent members 53 to 55 with the above arrangements are built into thehead protecting body 2 on the front surface of the impact-on-the-chin-and-cheek absorbing liner 23, as shown in FIG. 3. For this purpose, as shown in FIGS. 3, 5A and 5B, the front surface of theimpact absorbing liner 23 has the inverted U-shapedfront recess 45 substantially corresponding to the shape of the air supplypath forming member 53. That region of theimpact absorbing liner 23 which is surrounded by thefront recess 45 forms afitting projection 92 with the original thickness of theimpact absorbing liner 23. - As shown in FIGS. 3, 5A and5B, the impact-on-the-chin-and-
cheek absorbing liner 23 has a comparatively shallow (i.e., shallower than the front recess 45)recess 94 extending substantially horizontally under thefront recess 45 andprojection 92. Therecess 94 is symmetrical (i.e., axi-symmetrical) about the centrallongitudinal section line 40 shown in FIGS. 5A and 5B as the axis of symmetry, has a substantial T-shape, and reaches the lower end of theimpact absorbing liner 23. The left and right portions of the upper end of therecess 94 are continuous to thefront recess 45. Hence, rainwater or the like which is to stay in thefront recess 45 or at its vicinity is discharged from the lower end of theimpact absorbing liner 23 to the outside through the T-shapedrecess 94. - As shown in FIGS. 3, 5A and5B, the impact-on-the-chin-and-
cheek absorbing liner 23 has a pair of left and right side recesses or exhaust path recesses 93 a and 93 b respectively adjacent to lower left andright portions front recess 45. The exhaust path recesses 93 a and 93 b are continuous to thefront recess 45 on the left and right sides of thefront recess 45 which are opposite to the centrallongitudinal section line 40 side (i.e., the lower left andright portions - The pair of left and right exhaust path recesses93 a and 93 b are symmetrical (i.e., axi-symmetrical) about the central
longitudinal section line 40 of FIGS. 5A and 5B as the axis of symmetry. Thus, the leftexhaust path recess 93 a formed in the left half of the impact-on-the-chin-and-cheek absorbing liner 23 will be described in detail with reference to FIGS. 3, 5A and 5B, and a detailed description of the rightexhaust path recess 93 b will be omitted. - The
exhaust path recess 93 a has theexhaust hole 46 serving as its start point (i.e., an air inlet port to theexhaust path recess 93 a), as shown in FIGS. 5A and 5B. Theexhaust path recess 93 a extends from theexhaust hole 46 to the left (i.e., opposite to the centrallongitudinal section line 40 side, in other words, horizontally outward or outward to the left and right). Anupper surface 101,lower surface 102 andrear surface 103 of theexhaust path recess 93 a are used to form thechin exhaust path 122 a (to be described later). The front-side surface (i.e., the front surface) which opposes therear surface 103 of theexhaust path recess 93 a is formed by the rear surface of the defecting/partitioning plate 95 a of the air supplypath forming member 53, as will be described later. Accordingly, theexhaust path recess 93 a andpartitioning plate 95 a form the chin exhaust path main body that occupies most of thechin exhaust path 122 a (to be described later). Thechin exhaust path 122 a is comprised of the chin exhaust path main body and that half of the left air supply/exhaust hole 111 a of theouter shell 11 which is opposite to the centrallongitudinal section line 40 side (i.e., horizontally outer side). - As shown in FIGS. 5A and 5B, the rear surface (i.e., the bottom surface)103 of the
exhaust path recess 93 a forms a slant surface slightly slanting backward from theexhaust port 46 to the left (i.e., to the side opposite to the centrallongitudinal section line 40 side). A slant angle θ1 of this slant is about 2° in the embodiment shown in FIG. 5B but is generally preferably in the range of 0.5° to 5° from the viewpoint of practicality and is more preferably in the range of 1° to 3°. The front surface (i.e., the outer surface) of thepartitioning plate 95 a which forms a front surface opposing therear surface 103 of theexhaust path recess 93 a forms a slant surface, at least near its left end, slanting slightly forward from theexhaust port 46 to the left (i.e., to the side opposite to the centrallongitudinal section line 40 side). A slant angle θ2 (not shown) of this slant is about 2° in the embodiment shown in FIGS. 3 and 5B but is generally preferably in the range of 0.5° to 5° in practice and is more preferably in the range of 1° to 3°. - The chin region of the outer shell11 (i.e., a region opposing the chin of the wearer) has a pair of left and right air supply/
exhaust holes exhaust holes longitudinal section line 40 side to the opposite side (i.e., to the left and right outward). The air supply/exhaust holes exhaust holes longitudinal section line 40 side respectively oppose the left and rightlower portions path forming member 53. The halves (i.e., the other half) of the air supply/exhaust holes longitudinal section line 40 side oppose the exhaust path recesses 93 a and 93 b. Theouter shell 11 has anotch 112 at its substantially central portion, which is notched from the upper end downward, as shown in FIG. 5A. Thenotch 112 has a size substantially equal to the sum of the sizes of the projectingsurface 73 of the air supplyport forming member 55, the inverted U-shaped projectingridge 80 andupper opening 78 a. - To build the three types of chin ventilator constituent members (i.e., the air supply
path forming member 53, theshutter member 54 and the air supply port forming member 55) into thehead protecting body 2, the steps described in the following items (i) to (iv) may be sequentially performed. - (i) First, the
shutter member 54 is attached to the air supplyport forming member 55. - To perform this attaching operation, the
tap 89 of theshutter member 54 is inserted in theupper opening 78 a of the air supplyport forming member 55 from the inside toward the outside. After the wavedspring 79 rides over the engagedprojection 87 of theshutter member 54 from the inner side to the outer side by utilizing the elasticity of theprojections 85 of theshutter member 54 and the wavedspring 79 of the air supplyport forming member 55, the engagedprojection 87 is abutted against thestep 79 a of the wavedspring 79. In this state, when theshutter member 54 is moved substantially horizontally with respect to the air supplyport forming member 55, its engagedprojection 87 is fitted in the recess of the wavedspring 79 and held in position at three positions, i.e., the central position and the left and right positions. The substantially horizontal movement of theshutter member 54 is regulated as the connectingportion 88 abuts against the left and right surfaces of theupper opening 78 a of the air supplypath forming member 53. - (ii) The air supply
port forming member 55 attached with theshutter member 54 is temporarily attached to the air supplypath forming member 53. - To perform this attaching operation, the engaged
projections path forming member 53 are fitted in the engaging holes formed in the rear surfaces of theprojections port forming member 55. In this case, when necessary, theprojections projections ridge 60 c of the air supplypath forming member 53 is relatively fitted in the groove of thebend 81 of the air supplyport forming member 55. - (iii) The air supply
path forming member 53 attached with theshutter member 54 is attached to the inner surface of the chin region of theouter shell 11. - To perform this attaching operation, as shown in FIG. 5A, attaching screws (not shown) may be inserted in a pair of left and right screw insertion holes113, formed on the
outer shell 11, from the outer surface to the inner surface, then in the pair of left and right screw insertion holes 72 a and 72 b of the air supplyport forming member 55, and may be screwed into the pair of left and right attachingbosses path forming member 53. In this case, the projectingsurface 73 and invertedU-shaped projecting ridge 80 of the air supplyport forming member 55 are inserted in thenotch 112 of theouter shell 11, and the lower portion and tap 89 of the connectingportion 88 of theshutter member 54 project forward from thenotch 112. The member main body 71 (excluding the thin-walled portions 71 a), the projectingridge 74 a and the hangingportion 77 of the air supplyport forming member 55, and the invertedU-shaped bend 60, those sides of the pair of left and right bends 61 a and 61 b, which are opposite to the centrallongitudinal section line 40 side, and lower ends of the left and rightlower portions guide plates 62 a to 64 a and 62 b to 64 b depending on the case) of the air supplypath forming member 53 abut against the inner surface of theouter shell 11. As shown in FIG. 3, the left and rightlower portions main body 56 of the air supplypath forming member 53 respectively oppose those halves of the pair of left and right air supply/exhaust holes longitudinal section line 40 side, of theouter shell 11. - (iv) The outer surface of the impact-on-the-chin-and-
cheek absorbing liner 23 is abutted against the inner surface of theouter shell 11 and attached to it with an adhesive or the like. - This attaching operation is performed such that the
fitting projection 92 of the impact-on-the-chin-and-cheek absorbing liner 23 is fitted in thefitting opening 57 of the air supplypath forming member 53, as shown in FIG. 3, and such that the almost or substantially entire air supplypath forming member 53 is relatively fitted in thefront recess 45 of theimpact absorbing liner 23. As a result, as shown in FIG. 3, the pair of left and right exhaust path recesses 93 a and 93 b of theimpact absorbing liner 23 respectively oppose those halves of the pair of left and right air supply/exhaust holes longitudinal section line 40 side, of theouter shell 11. In this case, as shown in FIGS. 1 and 2, a conventionally knownbreath guard 114 may be interposed between the outer surface (i.e., the front surface) of the impact-on-the-chin-and-cheek absorbing liner 23, and the inner surfaces (i.e., rear surfaces) of theouter shell 11 and air supplypath forming member 53, thereby attaching thebreath guard 114 to thehead protecting body 2. - Through the steps described in the above items (i) to (iv), the three types of chin ventilator
constituent members 53 to 55 can be built in thehead protecting body 2. In the built-in state, thechin ventilator mechanism 51 has the chinair supply path 121 and the pair of left and rightchin exhaust paths - The chin
air supply path 121 is sequentially comprised of - 1) those halves of the pair of left and right air supply/
exhaust holes longitudinal section line 40 side, of theouter shell 11, - 2) a pair of left and right (i.e., two) gaps defined by the outer surfaces of the left and right
lower portions path forming member 53 and the inner surface of theouter shell 11 and including the lower portions of the straighteningair supply paths 65 a to 67 a and 65 b to 67 b, - 3) one gap defined by the outer surface of the air supply
path forming member 53, the inner surface of the air supplyport forming member 55 and the inner surface of theshutter member 54, and including the upper portions of the straighteningair supply paths 65 a to 67 a and 65 b to 67 b, and - 4) the
notches 84 of theshutter member 54 and thenotches 75 of the air supplyport forming member 55 from its start point (i.e., the air inlet port to the chin air supply path 121) to its end point (i.e., the air outlet port from the chin air supply path 121). The start point of the chinair supply path 121 is formed by the outer surfaces of those halves of the pair of left and right air supply/exhaust holes longitudinal section line 40 side, of theouter shell 11. These outer surfaces form the air inlet port to the chinair supply path 121. The end point of the chinair supply path 121 is formed by the upper ends of thenotches 75 of the air supplyport forming member 55. These upper ends form the air outlet port from the chinair supply path 121. Hence, the chinair supply path 121 branches into two branches from the end point toward the start point. The three gaps described in the above items 2) and 3) respectively form air supply gaps. Accordingly, the three types of chin ventilatorconstituent members 53 to 55 and the chin region of theouter shell 11 make up the chin air supply path main body that occupies most of the chinair supply path 121. The chinair supply path 121 is comprised of the chin air supply path main body and one halve of the air supply/exhaust hole 111 a described in the item 1). - When the wearer wearing the full-face-
type helmet 1 drives a motor cycle, outer air (i.e., external air) flows relatively from the substantially front surface into the air supply/exhaust holes exhaust holes longitudinal section line 40 side, serve as the air supply hole portions of the chinair supply path 121. The external air flows from thenotches shield plate 4 through the two gaps described in the item 2) and one gap described in the item 3), as shown in FIGS. 2 and 3. Therefore, the external air can be introduced into thehead protecting body 2 through the chinair supply path 121. The external air is straightened by the straighteningair supply paths 65 a to 67 a and 65 b to 67 b while it flows upward in the three gaps described in the items 2) and 3). The external air flowing to near the lower end of the inner surface of the shield plate 4 (i.e., above the substantially central portion of the impact-on-the-chin-and-cheek absorbing liner 23 and above the breath guard 114) shifts upward along the inner surface of theshield plate 4 to reach near the upper end of the inner surface of theshield plate 4. As a result, the external air flow can effectively prevent theshield plate 4 from being fogged by the breath exhaled by the wearer. - The chin
air supply path 121 can be blocked by operating theshutter member 54. More specifically, when the engagedprojection 87 of theshutter member 54 engages with the central one of the three engaging recesses of the wavedspring 79, the projections (i.e., the blocking portions) 85 of theshutter member 54 block the notches (i.e., air outlet ports) 75 of the air supplyport forming member 55. When the wearer holds thetap 89 of theshutter member 54 and moves theshutter member 54 to the left or right so the engagedprojection 87 of theshutter member 54 engages with another engaging recess, other than the central one, of the wavedspring 79, theprojections 85 of theshutter member 54 are displaced from thenotches 75 of the air supplyport forming member 55 to substantially overlie on theprojections 76. Hence, theair outlet ports 75 of the air supplyport forming member 55 are opened. Therefore, when the wearer operates theshutter member 54 to engage the engagedprojection 87 with the central engaging recess of the wavedspring 79, the chinair supply path 121 can be blocked so air supply through it can be stopped. - The pair of left and right
chin exhaust paths longitudinal section line 40 shown in FIGS. 5A and 5B as the axis of symmetry. Hence, the leftchin exhaust path 122 a will be described in detail with reference to FIGS. 3, 4, 5A and 5B, and a detailed description on the rightchin exhaust path 122 b will be omitted. - The left
chin exhaust path 122 a is sequentially comprised of - 1) the
exhaust port 46 of the left half of the impact-on-the-chin-and-cheek absorbing liner 23, - 2) the space surrounded by the upper, lower and
rear surfaces exhaust path recess 93 a of the left half of the impact-on-the-chin-and-cheek absorbing liner 23 and the defecting/partitioning plate 95 a of the left half of the air supplypath forming member 53, and - 3) that half (i.e., the other half) of the air supply/
exhaust hole 111 a, which is opposite to the centrallongitudinal section line 40 side, of theouter shell 11 - from its start point (i.e., the air inlet port to the
chin exhaust path 122 a) to its end point (i.e., the air outlet port from thechin exhaust path 122 a). The start point of the leftchin exhaust path 122 a is formed by the inner surface of theexhaust port 46 of the left half of theimpact absorbing liner 23. This inner surface forms the air inlet port to the leftchin exhaust path 122 a. The end point of the leftchin exhaust path 122 a is formed of the outer surface of that half of the air supply/exhaust hole 111 a, which is opposite to the centrallongitudinal section line 40 side, of theouter shell 11. This outer surface forms the air outlet port from theleft exhaust path 122 a. The space described in the item 2) forms an exhaust gap. - When the wearer wearing the full-face-
type helmet 1 drives a motor cycle, as described above, the external air flows relatively from the substantially front surface into the other half of the air supply/exhaust hole 111 a described in the item 3). Simultaneously, the external air abutting against near the central portion of the chin region of the outer surface of theouter shell 11 is deflected horizontally outward (i.e., from the centrallongitudinal section line 40 side to the left opposite to it) along the outer surface of theouter shell 11, and flows backward. In this case, the external air flowing relatively from the substantially front surface into the other half of the air supply/exhaust hole 111 a described in the item 3) is blocked by thefront surface 103 of theexhaust path recess 93 a in the left half of the impact-on-the-chin-and-cheek absorbing liner 23 (in this case, the slant angle θ1 of thisfront surface 103 functions or a negative pressure is produced as will be described later), and is deflected horizontally outward. Also, of the external air deflected horizontally outward along the outer surface of theouter shell 11, external air flowing to that half of the air supply/exhaust hole 111 a described in item 3), which is on the centrallongitudinal section line 40 side, is deflected horizontally outward by the defectingplate 95 a described in the item 2), as shown in FIG. 3. Hence, this external air flows out from that half of the air supply/exhaust hole 111 a described in the item 3), which is on the centrallongitudinal section line 40 side, and flows away horizontally outward in front of the other half of the air supply/exhaust hole 111 a along the outer surface of theouter shell 11. This produces the negative pressure near the outer end of theexhaust path recess 93 a and near the other half of the air supply/exhaust hole 111 a described in the item 3). - Air in the impact-on-the-chin-and-
cheek absorbing liner 23, below thebreath guard 114 and near theexhaust hole 46 described in the item 1) (i.e., internal air including breath exhaled by the wearer and near the intermediate position in the vertical direction of the chin region of the impact absorbing liner 23) flows into thisexhaust hole 46, reaches the other half of the air supply/exhaust hole 111 a described in the item 3) through the space described in the item 2), and flows out of theouter shell 11 from this other half. Hence, that half of the air supply/exhaust hole 111 a, which is opposite to the centrallongitudinal section line 40 side, serves as the exhaust hole portion of thechin exhaust path 122 a. Since air in thehead protecting body 2 can be exhausted to the outside through thechin exhaust path 122 a, theshield plate 4 can be prevented further effectively from being fogged by the breath exhaled by the wearer or the like. - As shown in FIGS. 2 and 6, the
head ventilator mechanism 52 has one or a plurality of (in the embodiment shown in FIGS. 2 and 6, a pair of left and right)ventilation grooves 131 extending substantially semicircularly from the front end to the rear end (in other words, from the front head region to the nape region through the top head region and back head region) through the substantially central portion, in the right-to-left direction, of the inner surface (i.e., inner circumferential surface) of the impact-on-the-head absorbing liner 21. Theventilation grooves 131 serve as head air paths, and are wide from their start points to near the front head region and narrow from there to the top head region. Thehead ventilator mechanism 52 has thebacking cover 22 covering almost or substantially the entire inner surface of the impact-on-the-head absorbing liner 21, as described above. Thebacking cover 22 has a large number ofventilation openings 141. Theventilation openings 141 serve as air supply openings or exhaust openings depending on their positions or how the helmet is used (i.e., the open/closed states ofshutter members head ventilator mechanism 52 is comprised of aforehead ventilator portion 132, fronthead ventilator portion 133, backhead ventilator portion 134 andnape ventilator portion 135 respectively formed along theventilation grooves 131. Hence, in the following description, theforehead ventilator portion 132, fronthead ventilator portion 133, backhead ventilator portion 134 andnape ventilator portion 135 will be described in separate items with reference to FIGS. 2 and 6. - As described above, the
forehead ventilator portion 132 has theventilation openings 31 formed in the front-side engagedmember 25 of thebacking cover 22 and theventilation openings 32 formed in the front-side engagedmember 27 of the impact-on-the-head absorbing liner 21. Theventilation openings 31 are continuous to theventilation grooves 131 through theventilation openings 32. - Hence, as described above, the external air introduced into the
head protecting body 2 through the chinair supply path 121 and reaching near the upper end of the inner surface of theshield plate 4 flows into theventilation grooves 131 through theventilation openings head ventilator portion 133 through theventilation grooves 131. - The front
head ventilator portion 133 has a pair of left and right air supplyhole forming members 142 attached to theouter shell 11, and theshutter members 143 respectively attached to the air supplyhole forming members 142. Thus, the pairs of left and right air supplyhole forming members 142 andshutter members 143 correspond to the pair of left and right air supply/exhaust holes outer shell 11 and the impact-on-the-head absorbing liner 21 respectively have air supply holes. The air supply holes formed in theouter shell 11 fit on cylindrical airsupply hole portions 142 a of the air supplyhole forming members 142. The air supply holes formed in the front head region of the impact-on-the-head absorbing liner 21 are continuous to theventilation grooves 131, and oppose theventilation openings 141 formed in thebacking cover 22 through theventilation grooves 131. Also, theshutter members 143 are slidably attached to the air supplyhole forming members 142 such that they can selectively open and close the outer ends of the airsupply hole portions 142 a of the air supplyhole forming members 142. - When the
shutter members 143 are open, the first air flow flowing through theventilation grooves 131 from the forehead region toward the front head region of thehead protecting body 2 merges with the second air flow flowing from the outside into theventilation grooves 131 through the airsupply hole portions 142 a. When theshutter members 143 are closed, the first air flow further flows as a single flow toward the back head region through theventilation grooves 131. When the first and second air flows merge, part of the merged air (mainly the second air flow portion) flows into the interior of thehead protecting body 2 near the front head region through theventilation openings 141 of thebacking cover 22. - The back
head ventilator portion 134 has a pair of left and right exhausthole forming members 144 attached to theouter shell 11, and theshutter members 145 respectively attached to the exhausthole forming members 144. Thus, the pairs of left and right exhausthole forming members 144 andshutter members 145 correspond to the pairs of left and right air supplyhole forming members 142 andshutter members 143, and air supply/exhaust holes outer shell 11 look simple. The back head regions of theouter shell 11 and impact-on-the-head absorbing liner 21 respectively have exhaust holes. The exhaust holes formed in theouter shell 11 fit on cylindrical exhaust holes 144 a of the exhausthole forming members 144. The exhaust holes formed in the back head region of the impact-on-the-head absorbing liner 21 are continuous to theventilation grooves 131, and oppose theventilation openings 141 formed in thebacking cover 22 through theventilation grooves 131. Also, theshutter members 145 are slidably attached to the exhausthole forming members 144 such that they can selectively open and close the outer ends of the exhaust holes 144 a of the exhausthole forming members 144. - When the
shutter members 145 are open, the first air flow flowing through theventilation grooves 131 from the front head region toward the back head region of thehead protecting body 2 slightly merges with the second air flow flowing out from the inside of thebacking cover 22 through theventilation grooves 131 andexhaust holes 144 a. When theshutter members 145 are closed, the first air flow further flows substantially entirely toward the back head region through theventilation ridge grooves 131. - The
nape ventilator portion 135 is shown in enlargement in FIG. 6. Referring to FIG. 6, the main body portion of thebacking cover 22 is formed of porousnonwoven fabric 147 to which appropriate-shapedelastic blocks 146 made of a flexible elastic material such as urethane foam or another synthetic resin are attached with an adhesive or the like. The rear-side engagedmember 26 is attached to the main body portion, which is on theelastic blocks 146 side, as described above. Theventilation openings 33 of the rear-side engagedmember 26 are continuous to theventilation grooves 131 through theventilation openings 34 of the rear-side engaging member 28 of the impact-on-the-head absorbing liner 21. - An exhaust
port forming member 151 is attached to the lower end face of the rear portion of the impact-on-the-head absorbing liner 21 with a tape, adhesive, or the like. The exhaustport forming member 151 is comprised of abase plate portion 151 a which forms the lower end face of the rear portion of thehead protecting body 2, and a pair of left andright exhaust ports 151 b formed by expanding part of a pair of left and right portions of thebase plate portion 151 a like bags such that their longitudinal sections form almost triangular shapes. Eachexhaust port 151 b has a large number of slit-like inner exhaust holes 152 formed in a wall portion in front of theexhaust port 151 b, and anouter exhaust hole 153 formed by boring the lower end of theexhaust port 151 b entirely. Theouter exhaust holes 153 are continuous to theventilation grooves 131 through the inner exhaust holes 152. Hence, the outer ends of theouter exhaust holes 153 form the end points (i.e., air outlet ports) of the ventilation grooves (i.e., head air paths) 131. - The
outer shell 11 has a narrow orconstricted portion 11 a in the outer surface of the nape region at its rear portion to extend substantially horizontally. In the embodiment shown in FIG. 6, theconstricted portion 11 a is narrowed or constricted forward by about 9 mm (about 10 mm from the lower end of the rear portion of the lower rim member 12), from the lower end of the rear portion of theouter shell 11, on the center line in the right-to-left direction of theouter shell 11. The radius of curvature of theconstricted portion 11 a on this center line is about 15 mm. For this reason, that portion of the outer shell 11 (and accordingly the lower rim member 12) which is near the lower end of its rear portion slants downward from above in the backward direction on the center line, as shown in FIG. 6. A slant angle θ3 of this slant is about 30°. Theconstricted portion 11 a is constricted the most on the center line of the rear portion of theouter shell 11, and is constricted less forward along the left or right side. Theconstricted portion 11 a has a length in the back-and-forth direction of as large as about 50 mm, and a length in the right-to-left direction of as large as about 16 cm. The impact-on-the-head absorbing liner 21 also has a narrow orconstricted portion 21 a in the same manner as theouter shell 11. Theconstricted portion 21 a is substantially in tight contact with theconstricted portion 11 a of theouter shell 11. - Hence, the air flow flowing relatively along the rear portion of the outer surface of the
outer shell 11 is deflected by theconstricted portion 11 a sharply backward, so a portion near under theouter exhaust holes 153 of the exhaustport forming member 151 becomes a negative pressure. Thus, the first air flow flowing through theventilation grooves 131 toward the nape region, and the second air flow flowing from the interior of thehead protecting body 2 into theventilation grooves 131 through the large number of clearances of the porousnonwoven fabric 147, theventilation openings 33 of the rear-side engagedmember 26, and theventilation openings 34 of the rear-side engaging member 28 flow out from theouter exhaust holes 153 effectively through the inner exhaust holes 152 of the exhaustport forming member 151. Thus, the air flow in theventilation grooves 131 can be improved by thenape ventilator portion 135. - The constricted
portion 11 a generally preferably satisfies one or more of the conditions described in the following items 1) to 5) in practice: - 1) the constricted
portion 11 a should be constricted forward by 4 mm to 16 mm (more preferably by 6 mm to 12 mm) from the lower end of the rear portion of theouter shell 11, or by 5 mm to 17 mm (more preferably by 7 mm to 13 mm) from the lower end of the rear portion of thelower rim member 12, on the center line in the right-to-left direction of theouter shell 11; - 2) the radius of curvature on this center line should be in the range of 6 mm to 25 mm (more preferably 10 mm to 20 mm);
- 3) that portion of the
outer shell 11 orlower rim member 12 which is near the lower end of its rear portion should slant downward from above in the backward direction on the center line in the range of 20° to 40° (more preferably 25° to 35°) (in other words, the slant angle θ3 should be in the range of 20° to 40° (more preferably 25° to 35°)); - 4) the length in the back-and-forth direction should be in the range of 25 mm to 100 mm (more preferably 35 mm to 75 mm); and
- 5) the length in the right-to-left direction should be in the range of 8 cm to 32 cm (more preferably 12 cm to 24 cm).
- Having described a specific preferred embodiment of this invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to that precise embodiment, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.

air supply path 121 of thechin ventilator mechanism 51 is comprised of the air supply/exhaust holes outer shell 11 and three types of chin ventilatorconstituent members 53 to 55, and thechin exhaust paths chin ventilator mechanism 51 are comprised of the air supply/exhaust holes outer shell 11, the exhaust holes 46 and exhaust path recesses 93 a and 93 b of the impact-on-the-chin-and-cheek absorbing liner 23, and the defecting/partitioning plates path forming member 53. Alternatively, thechin exhaust paths exhaust holes outer shell 11. - In the above embodiment, the pair of left and right air supply/
exhaust holes outer shell 11, and the center-side halves of the air supply/exhaust holes outer shell 11, the substantially central portion of this air supply/exhaust hole may be used as an air supply hole portion, and those portions of this supply/exhaust hole which correspond to the left and right sides of the air supply hole portion may be used as a pair of left and right exhaust hole portions. - In the above embodiment, the opening/
closing shutter portion 83 of theshutter member 54 slides along the lower surface of the inner air supplyport forming portion 74 of the air supplyport forming member 55. Alternatively, the opening/closing shutter portion 83 may slide along the upper surface of the inner air supplyport forming portion 74. - In the above embodiment, the
ventilation grooves 131 with open loop-like longitudinal sections are formed in the inner surface of thehead protecting body 2 in order to form head air paths. Alternatively, in place of theventilation grooves 131 with the open loop-like longitudinal sections, closed loop-like elongated holes with circular longitudinal sections may be formed. In this case, the impact-on-the-head absorbing liner 21 may be halved into an outer liner portion on theouter shell 11 side and an inner liner portion opposite to theouter shell 11 side, and opposing grooves with open loop-like longitudinal sections may be formed in the inner surface of the outer liner portion and the outer surface of the inner liner portion. This pair of grooves can form elongated ventilation holes with closed loop-like longitudinal sections. - In the above embodiment, the present invention is applied to the
chin ventilator mechanism 51. The present invention can also be applied to other mechanisms or portions such as the fronthead ventilator portion 133 of thehead ventilator mechanism 52. - In the above embodiment, the present invention is applied to the full-face-
type helmet 1. Alternatively, the present invention can also be applied to helmets of other types, i.e., a jet- or semijet-type helmet, or a full-face-type helmet serving also as a jet-type helmet, the chin portion of which can be raised.
