Abstract
A motor bracket is attached at one end of a vehicle body so as to be able to slide, and is fixed at the other end to the vehicle body. And weak points are provided in the vicinity of a motor bracket fixing section. Weak points are also provided in the vicinity of a first fixing section of a first pivot holder. On the other hand, weak points are also provided in the vicinity of a second fixing section of a second pivot holder. Since the motor bracket slides and becomes detachable if the weak points are ruptured, it is possible to absorb an impact at the wiper motor. Since the first and second pivot holders are also detached if the weak points and weak points are ruptured, it is possible to improve the overall impact absorbing performance of the vehicle wiper assembly.

A vehicle wiper assembly having a swingable wiper arm provided in the vicinity of a windshield and a wiper blade attached to a tip end of said wiper arm for wiping said windshield, comprising:
- a wiper motor for driving said wiper arm, said wiper motor being attached to a vehicle body via a first fixing section so as to move inside the vehicle body by an external force;
- and
- a support member for supporting said wiper motor, having a first end and an opposite second end, the support member swingably attached to the vehicle body at the first end and fixed to the vehicle body at the second end, the first fixing section being located at the second end, and
- a first weak section having low rupture strength provided between said wiper motor and said first fixing section.
A vehicle wiper assembly having a first swingable wiper arm and a second swingable wiper arm provided in the vicinity of a windshield and a wiper blade attached to a tip end of each wiper arm for wiping said windshield comprising:
- a wiper motor for driving said first and second wiper arms, said wiper motor being attached to a vehicle body via a first fixing section so as to move inside the vehicle body by an external force;
- a support member for supporting said wiper motor, having a first end and an opposing second end, the support member being swingably attached to the vehicle body at the first end and fixed to the vehicle body at the second end, the first fixing section being located at the second end, and
- a first weak section having low rupture strength provided between said wiper motor and said first fixing section.
A vehicle wiper assembly having a first swingable wiper arm and a second swingable wiper arm provided in the vicinity of a windshield and a wiper blade attached to a tip end of each wiper arm for wiping said windshield comprising:
- a wiper motor for driving said first and second wiper arms, said wiper motor being attached to a vehicle body via a first fixing section so as to move inside the vehicle body by an external force;
- a first weak section having low rupture strength provided between said wiper motor and said first fixing section;
- a first support member for supporting said first wiper arm, having a first end and an opposing second end, the first support member fixed to the vehicle body at the first end via a second fixing section, said first wiper arm being attached to the first support member at the second end;
- a second weak section having low rupture strength provided between said second fixing section and said second end;
- a second support member for supporting said second wiper arm, having a third end and an opposing fourth end, the second support member fixed to the vehicle body at the third end via a third fixing section, said second wiper arm being attached to the second support member at the fourth end;
- and
- a third weak section having low rupture strength provided between said third fixing section and said fourth end.
A vehicle wiper assembly, comprising:
- a wiper motor;
- a bracket device supporting said wiper motor at a motor support section of said bracket device, said bracket device further including a vehicle body fixing section spaced from said motor support section along a length of said bracket device, said bracket device further including a first weak section having a low rupture strength and said first weak section being positioned between said vehicle body fixing section and said motor support section relative to a length of said bracket device such that said wiper motor is free to move further inside the vehicle upon an external force rupturing said first weak section;
- a first pivot shaft for supporting a first wiper blade and a second pivot shaft for supporting a second wiper blade;
- a first pivot holder and a second pivot holder each having a vehicle attachment section and each having a pivot shaft holder section for respective holding of said first and second pivot shafts;
- and
- a pipe secured at a first end to said first pivot holder and at a second end to said second pivot holder, and said bracket device having a pipe connection section which is connected to said pipe.
