[ More specifically, male-type reinforcing rib 1217M and female-type reinforcing rib 1217F extend from lateral fitting edge 1274 of the fitting edge of adapter sheet 1270. The male reinforcement rib 1217M and the male reinforcement rib 1217F are bent inward and are engaged through the shape engaging of the dovetail projections 1217DP and the dovetail recesses 1217DR. Thus, the center lever 1210 is reinforced against the force applied to the side wall 1211 in the transverse direction D2.

As described above, the center lever 1210 is formed by pressing a metal plate. The spoiler 1215 and the reinforcing rib 1217 described above are also formed in the center lever 1210 through such pressing. With regard to the reinforcing ribs 1217, the male reinforcing ribs 1217M and the female reinforcing ribs 1217F are bent and mutually coupled through the press working to form the reinforcing ribs 1217. [

The adapter seat 1270 includes a seat opening 1271 that is open to the center lever 1210. The seat opening 1271 enters a predetermined depth from the front and rear upper walls 1212F and 1212R to the side wall 1211 and has an elongated U shape when viewed from the front of the center lever 1210. [ The adapter sheet 1270 has fitting edges 1272, 1273 and 1274 extending along the edges of the adapter sheet 1270 because the adapter sheet 1270 is pierced in the center lever 1210. The fitting edges 1272,1273 and 1274 fit into the bracket 2100 of the adapter assembly 2000 and the bracket 2100 seats on the adapter seat 1270.

A wiper blade adapter 2200 is rotatably coupled to the rotary shaft 2130. The rotary shaft 2130 extends in the transverse direction D2 and protrudes outside the support wall 2132. [ The rotary shaft 2130 has a slope 2131 at both ends thereof. A boss 2133 is formed on each side surface of the support wall 2132. The support wall 2132 can contact the inner surface of the wiper blade adapter 2200 through the boss 2133.

The bracket 2100 includes a fitting groove into which a portion of one lever (e.g., the center levers 1210 and 1210A) of the lever assembly 1200 (e.g., the aforementioned fitting edge of the adapter sheet 1270) And a bracket latch that elastically couples to a part of the lever. The bracket 2100 is attached to the adapter sheet 1270 of the center lever 1210 at the front end 2161 (one end in the longitudinal direction D1) and the rear end 2162 (the other end in the longitudinal direction D1) Lt; / RTI > Specifically, the front end 2161 of the bracket 2100 is engaged with the front fitting edge 1272 of the adapter sheet 1270, and the bracket 2100 is rotated about the front end 2161 as a fulcrum and center, ) With the rear fitting edge 1273 of the adapter sheet 1270. [ The fitting edges (e.g., the front fitting edge 1272, the rear fitting edge 1273, and the lateral fitting edge 1274) of the adapter sheet 1270 are fitted in the fitting groove of the bracket 2100 , The bracket latch of the bracket 2100 is resiliently coupled to the fitting edge of the adapter sheet 1270 by snap engagement.

The fitting groove of the bracket 2100 extends along the edge of the bracket 2100 (e.g., the edge of the front end and the rear end of the upper wall 2111 and the edge of the side wall 2112). The fitting groove has a front fitting edge 2141 formed between the front edge of the upper wall 2111 formed with the cutout 2116 and the lateral rib 2121A and the hook 2125, A rear fitting groove 2142 formed between the rear end edge of the upper wall 2111 and the rear ends of the longitudinal ribs 2122A and 2122B and a rear fitting groove 2142 formed between the rear ends of the vertical ribs 2122A and 2122B and the side wall 2112 And a side fitting groove 2143 formed therein. The front fitting edge 1272 fits into the front fitting groove 2141 and the rear fitting edge 1273 fits into the rear fitting groove 2142 and the lateral fitting edge 1274 is fitted to the side fitting groove 2141. [ (2143).

In this embodiment, the bracket latch 2133 is located at the rear end 2162 of the bracket 2100. The bracket latch 2150 is located within the recess 2117 formed in the trailing edge of the top wall 2111 and resiliently engages the front fitting edge 1272 or the rear fitting edge 1273 by snap engagement. The bracket latch 2150 extends outward in the longitudinal direction D1 from the lower end of the transverse rib 2121B. When the bracket 2100 is viewed from the front, the bracket latch 2150 has a J-shape. As another example, the bracket latch 2150 may have an I or C shape. Thus, the bracket latch 2150 can be resiliently deformed in the longitudinal direction D1.

The bracket latch 2150 includes a latch bar 2151 integrally formed at the lower end of the transverse rib 2121B at one end and having a free end and a latch bar 2151 located at the rear surface of the latch bar 2151 and below the free end of the latch bar 2151 And a wedge-shaped latching protrusion 2153 below the latching groove 2152. The engaging protrusion 2153 is formed of a metal plate. The latching groove 2152 of the bracket latch 2150 becomes a part of the fitting groove of the bracket 2150. That is, in this embodiment, the latching groove 2152 is a part of the rear fitting groove 2142, and is positioned inside the rear edge of the upper wall 2111. The bracket latch 2150 is configured to engage a portion of one of the levers (e.g., the center levers 1210 and 1210A) of the lever assemblies 1200 and 1200A (e.g., the front fitting edge 1272 of the adapter seat 1270 or the rear fitting (The edge 1273). The bracket latch 2150 engages the lower surface of the front fitting edge 1272 or the rear fitting edge 1273 on the upper surface of the latching protrusion 2153. The bracket latch 2150 is provided above the latching groove 2152 with a blocking portion 2154 covering a part of one of the levers 1200 and 1200A. In this embodiment, the blocking portion 2154 has a substantially semicircular shape and protrudes from the free end of the latch bar 2151. When the bracket latch 2150 elastically couples to the fitting edge of the adapter sheet 1270, the blocking portion 2154 covers one of the indicators 1214L and 1214R of the center levers 1210 and 120A. That is, when the bracket latch 2150 is snap-engaged with one of the front and rear fitting edges 1272 and 1273, one of the front and rear fitting edges 1272 and 1273 is caught in the catching groove 2152, The indicator character (1214L or 1214R) adjacent to one of the front and rear fitting edges (1272, 1273) is covered by the portion (2154). The bracket latch 2150 has a pair of stoppers 2155 protruding forward from the front surface of the latch bar 2151. When the latch bar 2151 is elastically deformed forward, the stopper 2155 comes into contact with the lateral rib 2121B, so that excessive deformation of the latch bar 2151 is prevented.

For example, when the bracket 2100 is coupled to the adapter sheet 1270, the front fitting edge 2141 located at the front end 2161 of the bracket 2100 is fitted with the front fitting edge 1272 are fitted. The engaging hook 2125 is inserted under the front fitting edge 1272 and at the same time the front fitting edge 1272 is fitted in the front fitting groove 2141 and the end of the lateral fitting edge 1274 The front end 2161 of the bracket 2100 engages with the front fitting edge 1272 in such a manner that the region is fitted in the side fitting groove 2143. [ With the front end 2161 of the bracket 2100 engaged with the front fitting edge 1272, the bracket 2100 is rotated toward the adapter seat 1270 about the front fitting edge 1272, The edge 1274 is fitted in the side fitting groove 2143 and the rear fitting edge 1273 in which the instruction character 1214R is positioned comes into contact with the lower surface of the latching protrusion 2153. [ As the bracket 2100 is further rotated, the rear fitting edge 1273 is engaged with the latching groove 2152 of the bracket latch 2150 by snap engagement together with the elastic deformation of the latch bar 2151, 2100 are fully engaged with the adapter sheet 1270. When the bracket 2100 is completely engaged with the adapter sheet 1270, the indicator character 1214L is exposed through the cutout 2116 of the bracket 2100, . Therefore, it is possible to visually confirm to which of the left driving vehicle and the right driving vehicle the wiper blade 1000 is applied. Further, in contrast to the above-described coupling method, the bracket 2100 can be coupled to the adapter sheet 1270. That is, the rear fitting edge 1273 can be fitted to the front fitting groove 2141 in which the latching hook 2125 is located, and the bracket latch 2150 can be engaged with the front fitting edge 1272. In this case, the indicating character 1214R is exposed through the cutout 2116 of the bracket 2100, and almost all of the indicating character 1214L is covered by the covering portion 2154.

11, 12 and 18 to 21, the wiper blade adapter 2200 will be described. The wiper blade adapter 2200 includes a pair of side walls 2211 extending in the longitudinal direction D1 and a front bridge portion 2212F extending between the side walls 2211 and interconnecting the side walls 2211, And a portion 2212R.

The wiper blade adapter 2200 is rotatably coupled to the bracket 2100 by a side wall 2211 to which the rotation shaft 2130 is coupled. A shaft hole 2213 through which the both ends of the rotating shaft 2130 of the bracket 2100 are fitted is passed through the side wall 2211 at approximately the middle of the side wall 2211 in each side wall 2211. As another example, the shaft hole 2213 may be formed in the side wall 2211 to a depth not penetrating the side wall 2211. A guide surface 2214 inclined between the lower end of each side wall 2211 and the shaft hole 2213 is formed on the inner surface of each side wall 2211. When the wiper blade adapter 2200 is mounted on the bracket 2100, the rotary shaft 2130 comes into contact with the guide surface 2214 of the side wall 2211 at the slope 2131 at both ends thereof. As the wiper blade adapter 2200 is subsequently pressed against the bracket 2100, both ends of the rotary shaft 2130 are fitted to the shaft hole 2213 along the guide surface 2214 with slight deformation of the side wall 2211 .

The front bridge portion 2212F and the rear bridge portion 2212R are spaced apart with a shaft hole 2213 therebetween. The upper surfaces of the front and rear bridge portions 2212F and 2212R are flat and lower than the upper edge of the side wall 2211. [ The wiper blade adapter 2200 has stepped portions 2215L and 2215R extending in the longitudinal direction D1 between the upper edges of the respective side walls 2211 and the upper surfaces of the front and rear bridge portions 2212F and 2212R.

The upper contact groove 2231 extends in the longitudinal direction D1 between the side walls 2211 and has a width equal to or slightly larger than the width of the bar 311. [ At the outer end of the rear bridge portion 2212R in the longitudinal direction D1, a fitting protrusion 2232 protrudes into the upper contact groove 2231. [ The fitting protrusion 2232 has a shape fit into the opening 312 of the third wiper arm adapter 310. A concave surface 2212CS is formed in the upper surface (upper contact groove 2231) of the rear bridge portion 2212R in front of the fitting protrusion 2232. [ When the wiper blade adapter 2200 and the second wiper arm adapter 210 are engaged, the rear tongue 216R of the second wiper arm adapter 210 is positioned on the concave surface 2212CS.

A front rib 2216 extends from the front bridge portion 2212F. The front ribs 2216 are positioned lower than the front bridge portion 2212F. The wiper blade adapter 2200 includes a tongue 116 of the first wiper arm adapter 110 and a front tongue 216F of the second wiper arm adapter 210 between the side walls 2211 and above the front rib 2216. [ And the offset portion 313 of the third wiper arm adapter 310. A wedge-shaped stopper projection 2217 protrudes from the inner surface of the upper end of each side wall 2211 above the front rib 2216. The stopper projection 2217 can contact the upper surface of the offset portion 313 of the third wiper arm adapter 310. [ That is, when the wiper blade adapter 2200 and the third wiper arm adapter 310 are connected, the offset portion 313 is received between the side walls 2211 through the stopper protrusion 2217. The upper surface of the offset portion 313 can come into contact with the stopper projection 2217 so that the wiper blade adapter 2200 and the third wiper arm adapter 310 are connected by the stopper projection 2217 during the connection between the wiper blade adapter 2200 and the third wiper arm adapter 310. [ And the third wiper arm adapter 310 can be temporarily fixed.

The lower lug 2242 also has a vertical tab 2244 vertically protruding from the upper surface 2243 and substantially parallel to the outer surface of the side wall 2211. That is, the vertical tab 2244 is spaced apart from the outer surface of the side wall 2211. The tab 2244 has a slope 2245 that contacts a slope 2322 (see Figs. 21 and 22) of the adapter cover 2300 on the side facing the side wall 2211. Fig. The first and second wiper arm adapters 110 and 120 are coupled between the outer surface of each side wall 2211 and the vertical tab 2244 when the adapter assembly 2000 and the first and second wiper arm adapters 110 and 120 are engaged. The lower ends 115 and 215 of the side plates 112 and 212 and the lower end 2314 of the adapter cover 2300 are interposed. That is, when the side wall 2211 of the wiper blade adapter 2200 is inserted between the side plates 112, 212 of the first and second wiper arm adapters and the adapter cover 2300 is closed to the wiper blade adapter 2200, A pressure or a force is applied to the side plates 112 and 212 of the first and second wiper arm adapters toward the side wall 2211 by the adapter cover 2244 and the adapter cover 2300. [ Thus, the restraint in the transverse direction D2 between the wiper blade adapter 2200 and the first and second wiper arm adapters 110, 210 is reinforced.

The adapter cover 2300 will be described with reference to Figs. 10, 11, 22, and 23. Fig. The adapter cover 2300 is rotatably coupled to the axial protrusion 2219 of the wiper blade adapter 2200 at a front end 2331 (one end in the longitudinal direction D1) and has a free end 2332 To the rear contact portion 2222 of the wiper blade adapter 2200 by snap engagement. The adapter cover 2300 has a pair of side walls 2311 each corresponding to a pair of side walls 2211 of the wiper blade adapter 2200 and a top wall 2312 extending between the side walls 2311. The length of the side wall 2311 and the upper wall 2312 in the longitudinal direction D1 is longer than the length of the side plate 112 of the first wiper arm adapter and the length of the side plate 212 of the second wiper arm adapter. The length between the front end 2331 and the free end 2332 of the adapter cover 2300 in the longitudinal direction D1 is determined by the distance between the front contact portion 2221 (or the front lug 2223) and the rear contact portion 2222 Rear lug 2225). The height of the side wall 2311 in the vertical direction D3 is greater than the height of the side wall 2211 of the wiper blade adapter 2200 in the vertical direction D3. Thus, the adapter cover 2300 has a size and dimensions to accommodate the first wiper arm adapter 110 or the second wiper arm adapter 210 therein.

The adapter cover 2300 has a shaft hole 2313 formed in each side wall 2311 at a front end 2331 thereof. The shaft projection 2219 of the wiper blade adapter 2200 is fitted to the shaft hole 2313 so that the adapter cover 2300 is rotatably coupled to the wiper blade adapter 2200 at the front end 2331.
