Abstract

A power window actuator including an electric motor, a reduction gear train for reducing rotational speed of the motor and a linkage mechanism connected to the gear train opens and closes a pivotable quarter window or a rear side vent. The rotation of the motor is mechanically stopped by structural members totally enclosed in a housing containing the motor and the gear train when the pivotable window comes to a fully opened or a fully closed position. An electric current supply to the motor is automatically discontinued by operation of a controller. An output shaft connected to a final stage gear of the speed reduction mechanism is extended outwardly from both sides of the housing. The linkage mechanism is composed of a pair of first links connected to the extended output shaft and a second link pivotably connected to the first links, so that the first links do not drop off from the output shaft without being fastened by a fastening member. Thus, the assembling process of the linkage mechanism is simplified.

Claims

1. An actuator for opening and closing a pivotable window comprising:

an electric motor;

a housing containing the electric motor therein;

an output shaft for transmitting rotational torque of the electric motor, the output shaft being rotatably held in the housing and extending outwardly from two sides of the housing; and

a linkage mechanism connected to the output shaft for pivotally opening and closing the pivotable window, wherein;

the linkage mechanism includes a pair of first links and a second link, the pair of the first links being connected to the extended ends of the output shaft, the second link being pivotally connected to the pair of first links; and

a pair of slits for slidably receiving the pair of first links therein are formed on the second link, so that movement of the pair of first links in an axial direction of the output shaft is restricted.

2. An actuator for opening and closing a pivotable window comprising:

a housing;

an electric motor contained in the housing;

a rotational speed reduction mechanism contained in the housing, for reducing rotational speed of the electric motor, the rotational speed reduction mechanism having a train of a plurality of gears which include a first stage gear engaging with the electric motor and a final stage gear;

an output shaft rotatably held in the housing and connected to the final stage gear of the rotational speed reduction mechanism;

the output shaft being extended outwardly from two sides of the housing; and

a linkage mechanism connected to the output shaft for pivotally opening and closing the pivotable window, wherein;

the linkage mechanism includes a pair of first links, each connected to one of the ends of the extended output shaft, and a second link pivotably connected to the first links; and

the second link includes a pair of slits slidably receiving the first links therein, and restricting movement of the pair of first links in an axial direction of the output shaft.
