A wiper system wiper system for wiping a window is provided. The wiper system has an arm head and an arm retainer connected to the arm head via a pivot. The wiper system includes a latch for controlling pivoting of the arm retainer with respect to the arm head. The latch is configured to restrict pivoting of the arm retainer with respect to the arm head to an operating range close to the window when the latch is in a latched state. The latch is further configured to allow pivoting of the arm retainer with respect to the arm head from the operating range to a servicing position away from the window when the latch is in an unlatched state.

A windscreen wiper arm, particularly for automobiles, includes comprising a mounting head mountable on a drive shaft and an arm member pivotally connected to the mounting head by means of a pivot pin, and wherein the arm member can be pivoted between a wiping position, wherein the arm member extends parallel to a windscreen to be wiped, and an elevated position, wherein the arm member and/or a windscreen wiper blade to be attached thereto can be repaired or replaced, characterized in that the windscreen wiper arm is provided with locking means arranged to lock the arm member onto the pivot pin in order to prevent the arm member from disengaging from the pivot pin in the elevated position of the arm member.

An arm head includes a head-side engagement part with which a tension spring is engaged. An arm shank includes: a pair of sidewall parts disposed opposed to each other in a wiping direction; a top wall part provided on a side opposite to the wiping surface side of the pair of sidewall parts and connecting the sidewall parts to each other; a shank-side engagement part provided between the sidewall parts and with which the tension spring is engaged; and a spring accommodating recess provided at the top wall part and capable of accommodating a part of the tension spring. When the arm shank is raised, a part of the tension spring is accommodated in the spring accommodating recess, and when the arm shank is raised and viewed from a direction in which the sidewall parts are opposed to each other, the tension spring is hidden by the sidewall parts.

A wiper device includes: lock grooves provided at an arm head and recessed toward both sides in a wiping direction of a wiper blade; and lock claws provided at an arm shank and protruding toward both sides in the wiping direction of the wiper blade. By concave-convex mating of the lock grooves and the lock claws with each other, the arm shank is restricted from rotating by degrees (about 22 degrees) or more with respect to the arm head, and a state in which the arm shank stands up by degrees (about 20 degrees), which is smaller than degrees, with respect to the arm head is maintained.

The present disclosure provides a rear wiper and a vehicle. The rear wiper includes an arm support, having a first end portion and a second end portion, wherein the arm support is driven to pivot at the first end portion thereof, such that the rear wiper wipes a rear windshield, and a wiper arm, having a first connecting end, wherein the first connecting end is connected to the second end portion of the arm support, and the wiper arm is rotatable relative to the arm support between a first position close to the rear windshield and a second position away from the rear windshield. The wiper arm includes a stop part, which is located at the first connecting end and is capable of abutting against the arm support, and when the stop part abuts against the arm support, the wiper arm is in the second position.
