The handle 23 is composed of a handle base 23a, an ascending portion 23b, and a grip portion 23c. The handle base 23a is connected to the upper surface of the handle post 20b, and the handle base 23a is connected to an ascending portion 23b extending upward of the vehicle. Furthermore, a grip portion 23c extending toward the left and right of the vehicle is provided above the rising portion 23b.

把手柱20b如圖6所示，係由連接左右把手23之側構件20e、設於側構件20e之中央部之前圓弧部20d及後圓弧部20c所構成。又，前圓弧部20d自側構件20e向車輛前方突出，後圓弧部20c自側構件20e向車輛後方突出。再者，把手桿20a連接於側構件20e之中央部之下表面。 As shown in FIG. 6, the handle post 20b is composed of a side member 20e connecting the left and right handles 23, a front arc portion 20d and a rear arc portion 20c provided at the center of the side member 20e. In addition, the front arc portion 20d protrudes from the side member 20e toward the front of the vehicle, and the rear arc portion 20c protrudes from the side member 20e toward the rear of the vehicle. Furthermore, the handle bar 20a is connected to the lower surface of the central portion of the side member 20e.

於自把手桿20a之轉動軸L方向觀察之情形時，後圓弧部20c及前圓弧部20d為以轉動軸L為中心構成固定寬度之圓弧狀者。而且，於把手柱20b之側構件20e、前圓弧部20d及後圓弧部20c上配設有支座51。 When viewed from the direction of the rotation axis L of the handle lever 20a, the rear circular arc portion 20c and the front circular arc portion 20d are circular arcs having a fixed width with the rotation axis L as the center. Furthermore, a support 51 is provided on the side member 20e, the front circular arc portion 20d, and the rear circular arc portion 20c of the handle post 20b.

如圖6所示，支座51於把手柱20b上，配設於把手 23之上升部23b之間，相對於把手柱20b之轉動軸左右對稱地配置。支座51係由沿把手柱20b之上表面之基部51b、及自基部51b相對於把手柱20b之上表面垂直延伸之延伸部51a所構成。於延伸部51a安裝有保持器52a，基部51b之下表面與把手柱20b之上表面相接。基部51b構成為與把手柱20b之後圓弧部20c及前圓弧部20d之半徑大致相同之圓弧狀，於基部51b設置有導孔51c。導孔51c為設於基部51b之圓弧狀之長孔，與前圓弧部20d及後圓弧部20c同樣，位於以轉動軸L為中心之圓周上。 As shown in FIG. 6, the support 51 is disposed on the handle post 20b and is disposed on the handle Between the rising portions 23b of 23, they are arranged bilaterally symmetrically with respect to the rotation axis of the handle post 20b. The support 51 is composed of a base portion 51b along the upper surface of the handle post 20b, and an extension portion 51a extending vertically from the base portion 51b relative to the upper surface of the handle post 20b. A retainer 52a is attached to the extending portion 51a, and the lower surface of the base portion 51b is in contact with the upper surface of the handle post 20b. The base portion 51b is configured in an arc shape having substantially the same radius as the rear arc portion 20c and the front arc portion 20d of the handle post 20b, and the base portion 51b is provided with a guide hole 51c. The guide hole 51c is an arc-shaped long hole provided in the base portion 51b, and is located on the circumference centered on the rotation axis L, similar to the front arc portion 20d and the rear arc portion 20c.

於支座51之導孔51c卡合有卡止部55，支座51能夠滑動地卡止於把手柱20b。卡止部55係由銷55a與擋止件55b所構成，銷55a安裝於把手柱20b之側構件20e。銷55a被插入設於側構件20e之孔及支座51之導孔51c，於銷55a之上端部安裝有擋止件55b。藉此，側構件20e與支座51之基部51b卡止於銷55a之下端與擋止件55b之間。再者，銷55a之下端之外徑較安裝有銷55a之側構件20e之孔之外徑及導孔51c之寬度大地構成，擋止件55b之外徑較導孔51c之寬度大地構成。 A locking portion 55 is engaged with the guide hole 51c of the support 51, and the support 51 is slidably locked to the handle post 20b. The locking portion 55 is composed of a pin 55a and a stopper 55b. The pin 55a is attached to the side member 20e of the handle post 20b. The pin 55a is inserted into the hole provided in the side member 20e and the guide hole 51c of the holder 51, and a stopper 55b is attached to the upper end of the pin 55a. Thereby, the side member 20e and the base 51b of the support 51 are locked between the lower end of the pin 55a and the stopper 55b. The outer diameter of the lower end of the pin 55a is larger than the outer diameter of the hole of the side member 20e to which the pin 55a is mounted and the width of the guide hole 51c, and the outer diameter of the stopper 55b is larger than the width of the guide hole 51c.

於安裝於保持器52a之下部之充氣機53之下表面固定有纜線54之一端，纜線54無法相對轉動地安裝於充氣機53。而且，如圖3及圖4所示，纜線54自充氣機53之底部通過支座51間，並通過把手柱20b之前方朝前下方延伸。進而，纜線54沿配置於安全氣囊模組50a之下方之儀錶36之下表面36b向前下方延伸。 One end of the cable 54 is fixed to the lower surface of the inflator 53 installed at the lower portion of the retainer 52a, and the cable 54 is fixed to the inflator 53 so as not to rotate relatively. Furthermore, as shown in FIGS. 3 and 4, the cable 54 passes from the bottom of the inflator 53 through the support 51 and extends forward and downward through the front of the handle post 20 b. Furthermore, the cable 54 extends forward and downward along the lower surface 36b of the meter 36 disposed below the airbag module 50a.

於儀錶36之下表面36b，沿纜線54之延伸方向於前後設置有2個限制部37，限制纜線54相對於儀錶36之下表面36b 之位置。限制部37之前端部37a構成為鉤狀，將纜線54嵌入並保持於前端部37a之內側。又，前端部37a經由基部37b固定於儀錶36之下表面36b，限制部37與儀錶36構成為一體。藉此，相對於儀錶36，纜線54藉由限制部37而被固定。 On the lower surface 36b of the meter 36, two restricting portions 37 are provided at the front and back along the extending direction of the cable 54 to restrict the cable 54 relative to the lower surface 36b of the meter 36 The location. The front end portion 37a of the restricting portion 37 is formed into a hook shape, and the cable 54 is fitted and held inside the front end portion 37a. In addition, the front end portion 37a is fixed to the lower surface 36b of the meter 36 via the base portion 37b, and the restricting portion 37 and the meter 36 are integrally formed. With this, the cable 54 is fixed by the restricting portion 37 relative to the meter 36.

又，如圖4所示，於車輛側視下，相對於通過保持器52a之最前端並與轉動軸L平行之直線L1，儀錶36位於前方。相對於直線L1，儀錶36位於前方之區域，於後方之區域配置有保持器52a。而且，於保持器52a之最後端之配置高度上，保持器52a之最後端位於相對於直線L1相隔之位置。 In addition, as shown in FIG. 4, the meter 36 is positioned forward with respect to the straight line L1 passing through the foremost end of the retainer 52a and parallel to the rotation axis L, as viewed from the side of the vehicle. The meter 36 is located in the front area with respect to the straight line L1, and the retainer 52a is arranged in the rear area. In addition, the rearmost end of the retainer 52a is located at a position separated from the straight line L1 at the height of the rearmost end of the retainer 52a.

其次，針對具備上述構成之本發明之實施形態之作用進行說明。於轉動把手23之情形時，把手柱20b及把手桿20a與把手23一起以把手桿20a之轉動軸L為中心轉動。安全氣囊裝置50之保持器52a經由轉動機構60之支座51配置於把手柱20b上，安裝於充氣機53之纜線54由儀錶36之限制部37限制。因此，如圖6之二點鏈線所示，於保持器52a及支座51不轉動，把手柱20b轉動之情形時，僅卡止部55沿著導孔51c移動。再者，卡止部55之擋止件55b之外徑較導孔51c之寬度大地構成，故支座51於轉動軸L方向之移動被限制。 Next, the operation of the embodiment of the present invention having the above configuration will be described. When turning the handle 23, the handle post 20b and the handle lever 20a rotate together with the handle 23 about the rotation axis L of the handle lever 20a. The retainer 52a of the airbag device 50 is disposed on the handle post 20b via the support 51 of the turning mechanism 60, and the cable 54 attached to the inflator 53 is restricted by the restricting portion 37 of the meter 36. Therefore, as shown by the two-dot chain line in FIG. 6, when the retainer 52a and the holder 51 do not rotate, and the handle post 20b rotates, only the locking portion 55 moves along the guide hole 51c. Furthermore, since the outer diameter of the stopper 55b of the locking portion 55 is larger than the width of the guide hole 51c, the movement of the support 51 in the direction of the rotation axis L is restricted.

如此，於轉動把手23之情形時，安全氣囊裝置50之保持器52a不轉動，保持器52a之位置及方向相對於車輛維持於固定。即，將安全氣囊裝置50之保持器52a配置於由支座51、把手柱20b、卡止部55所構成之轉動機構60上，藉由限制部37限制連接於安全氣囊裝置50之纜線54之轉動。藉此，安全氣囊裝置50保持於固定之位置。 As such, when the handle 23 is turned, the retainer 52a of the airbag device 50 does not rotate, and the position and direction of the retainer 52a are maintained fixed relative to the vehicle. That is, the retainer 52a of the airbag device 50 is disposed on the rotating mechanism 60 composed of the support 51, the handle post 20b, and the locking portion 55, and the cable 54 connected to the airbag device 50 is restricted by the restricting portion 37 Of rotation. Thereby, the airbag device 50 is kept in a fixed position.

藉由限制安全氣囊裝置50相對於車輛轉動，於把手柱20b之上方維持其方向，使得安全氣囊52容易於乘坐者之頭部及上半身之附近向上方展開。又，於轉動把手23時，由於安全氣囊裝置50不轉動，故安全氣囊裝置50之質量不會對把手23之操作造成影響。 By restricting the rotation of the airbag device 50 relative to the vehicle and maintaining its direction above the handle post 20b, the airbag 52 can be easily deployed upward near the occupant's head and upper body. In addition, when the handle 23 is rotated, since the airbag device 50 does not rotate, the quality of the airbag device 50 does not affect the operation of the handle 23.

針對安全氣囊模組50a之動作進行說明。於二輪機車1之加速度感測器(未圖示)檢測出特定值以上之加速度之情形時，控制單元(未圖示)使充氣機53運作。藉此，充氣機53產生氣體。藉由充氣機53產生之氣體供給至保持器52a內之安全氣囊52。然後，安全氣囊52藉由流入之氣體而膨脹，安全氣囊52使保持器52a之一部分裂開，並自保持器52a向上方展開。藉此，安全氣囊52向上方展開。又，與把手23之轉動狀態無關地，維持安全氣囊裝置50相對於車輛之方向。再者，安全氣囊52展開時所產生之衝擊經由支座51、把手柱20b、把手桿20a而由頭管14接收。 The operation of the airbag module 50a will be described. When the acceleration sensor (not shown) of the two-wheeled locomotive 1 detects acceleration above a certain value, the control unit (not shown) causes the inflator 53 to operate. With this, the inflator 53 generates gas. The gas generated by the inflator 53 is supplied to the airbag 52 in the holder 52a. Then, the airbag 52 is inflated by the inflowing gas, the airbag 52 splits a part of the retainer 52a, and deploys upward from the retainer 52a. As a result, the airbag 52 is deployed upward. In addition, regardless of the turning state of the handle 23, the direction of the airbag device 50 relative to the vehicle is maintained. Furthermore, the impact generated when the airbag 52 is deployed is received by the head pipe 14 via the support 51, the handle post 20b, and the handle bar 20a.

如圖4所示，於車輛側視下，相對於通過保持器52a之最前端並與轉動軸L平行之直線L1，儀錶36於其配置之高度上位於最後端相對於直線L1相隔之位置。二輪機車1之駕駛者之頭部位於轉向軸20之軸線之附近且把手23之上方。因此，駕駛者之視線接近於直線L1之方向，設於較儀錶36之最後端更靠前方之儀錶36之顯示區域難以隱藏於保持器52a。 As shown in FIG. 4, when viewed from the side of the vehicle, with respect to the straight line L1 passing through the forefront of the retainer 52 a and parallel to the rotation axis L, the meter 36 is located at the rearmost end of the straight line L1 at the height of its arrangement. The head of the driver of the two-wheeled locomotive 1 is located near the axis of the steering shaft 20 and above the handle 23. Therefore, the driver's line of sight is close to the direction of the straight line L1, and the display area of the meter 36 provided in front of the rear end of the meter 36 is difficult to hide in the holder 52a.

如以上說明，根據應用本發明之實施形態，二輪機車1之安全氣囊裝置50具備充氣機53、藉由充氣機53釋出之氣體而膨脹之安全氣囊52、收納充氣機53與安全氣囊52之保持器52a，保持器52a設於把手桿20a之轉動軸L上，於保持器52a與把手桿 20a之間設有轉動機構60。根據該構成，即使操作把手23導致把手桿20a轉動，亦可藉由轉動機構60而使保持器52a不轉動地保持著保持器52a之方向。藉此，保持器52a相對於車輛之方向固定，無需考慮保持器52a轉動之情形，可使安全氣囊52成為有效率之形狀。而且，能夠緊密地構成安全氣囊52，使安全氣囊裝置50本身緊密地構成，即使於有限之空間亦能夠配置安全氣囊裝置50。藉由把手桿20a支撐安全氣囊裝置50之荷重，安全氣囊裝置50之荷重不會對把手23之操作造成影響。因此，能夠一面維持車輛之操作性，一面將安全氣囊裝置50設置於把手桿20a之上方。 As described above, according to the embodiment to which the present invention is applied, the airbag device 50 of the two-wheeled locomotive 1 includes the inflator 53, the airbag 52 inflated by the gas released by the inflator 53, the storage inflator 53 and the airbag 52 Holder 52a, which is provided on the rotation axis L of the handle lever 20a, between the holder 52a and the handle lever A rotating mechanism 60 is provided between 20a. According to this configuration, even if the handle lever 20 is rotated by operating the handle 23, the direction of the holder 52a can be held by the rotation mechanism 60 without rotating the holder 52a. Thereby, the retainer 52a is fixed with respect to the direction of the vehicle, and it is not necessary to consider the situation in which the retainer 52a rotates, and the airbag 52 can be made into an efficient shape. In addition, the airbag 52 can be closely configured, the airbag device 50 itself can be closely configured, and the airbag device 50 can be arranged even in a limited space. By supporting the load of the airbag device 50 by the handle bar 20a, the load of the airbag device 50 will not affect the operation of the handle 23. Therefore, the airbag device 50 can be installed above the handle bar 20a while maintaining the operability of the vehicle.

又，於車輛側視下，於儀錶36之上方配置有保持器52a，且於儀錶36設有限制保持器52a相對於儀錶36轉動之限制部37。根據該構成，於搭載於車輛之儀錶36設置限制部37，故能夠藉由儀錶之簡易之形狀之變更，構成限制保持器52a之轉動之限制部37。因此，可於有限之空間中，容易構成限制部37。又，能夠使連接於控制單元(未圖示)之安全氣囊裝置50之纜線54沿著連接於儀錶36之電氣系統之纜線配置，纜線54之佈線變得容易。 In addition, when viewed from the side of the vehicle, a retainer 52 a is arranged above the meter 36, and the meter 36 is provided with a restricting portion 37 that restricts rotation of the retainer 52 a relative to the meter 36. According to this configuration, the restricting portion 37 is provided on the instrument 36 mounted on the vehicle, so that the restricting portion 37 that restricts the rotation of the holder 52a can be configured by a simple change in the shape of the instrument. Therefore, the restricting portion 37 can be easily configured in a limited space. In addition, the cable 54 of the airbag device 50 connected to the control unit (not shown) can be arranged along the cable of the electrical system connected to the meter 36, and the wiring of the cable 54 becomes easy.

又，於充氣機53連接有纜線54，纜線54藉由限制部37而被固定。根據該構成，使用纜線54能夠將保持器52a之方向相對於車輛保持於固定位置，能夠有效活用有限之空間。又，不必於安全氣囊模組50a追加設置其他限制構件。 In addition, a cable 54 is connected to the inflator 53, and the cable 54 is fixed by the restricting portion 37. According to this configuration, the direction of the retainer 52a can be held at a fixed position with respect to the vehicle using the cable 54 and a limited space can be effectively utilized. In addition, it is not necessary to additionally provide another restricting member to the airbag module 50a.

又，於車輛側視下，儀錶36之最後端相對於通過保持器52a之最前端並與轉動軸L平行之直線L1而相隔配置。根據該構成，保持器52a於駕駛者之視野中難以與儀錶36重疊。因此，既確保儀錶36之辨視性，又能夠使儀錶36作為保持器52a之限制 部37之一部分發揮功能。 In addition, when viewed from the side of the vehicle, the rearmost end of the meter 36 is arranged at a distance from the straight line L1 passing through the forefront of the retainer 52a and parallel to the rotation axis L. According to this configuration, the holder 52a is difficult to overlap with the meter 36 in the driver's field of view. Therefore, while ensuring the visibility of the meter 36, the meter 36 can be restricted as the holder 52a Part of part 37 functions.

又，上述實施形態中，列舉二輪機車1作為跨坐型車輛之例進行說明，但本發明並不限定於此，本發明能夠應用於具備2個前輪或後輪之3輪跨坐型車輛、及具備4輪以上之跨坐型車輛。 In addition, in the above embodiment, the two-wheeled locomotive 1 is described as an example of a straddle-type vehicle. However, the present invention is not limited to this. The present invention can be applied to a 3-wheel straddle-type vehicle including two front wheels or rear wheels. And straddle type vehicles with more than 4 wheels.
