Abstract
The wiper device includes a wiper blade which extends in a longitudinal direction and at least one longitudinal strip that is pre-curved to have a curved shape when in a relaxed condition. The wiper device supports the wiper blade and biases the wiper blade into a curved shape. A connecting device is attached with the at least one longitudinal strip. The connecting device includes a two-piece base and a joint part which is pivotably connected with the two-piece base. The two-piece base includes a first piece, which is directly secured with the at least one longitudinal strip, and a second piece with laterally spaced apart side walls that are each J-shaped.
Claims16
A windscreen wiper device, comprising:
- a wiper blade extending in a longitudinal direction;
- at least one longitudinal strip that is pre-curved to have a curved shape when in a relaxed condition and supporting said wiper blade and biasing said wiper blade into a curved shape;
- a connecting device attached with said at least one longitudinal strip, said connecting device including a two-piece base and said connecting device including a joint part that is pivotably connected with said base;
- said two-piece base including a first piece which is directly secured with said at least one longitudinal strip and a second piece with laterally spaced apart side walls that are each J-shaped;
- each of said J-shaped side walls having a short leg and a long leg which are partially spaced from one another by an open space;
- each of said short legs having a circular projection;
- and
- said circular projections of said side walls extending in opposite lateral directions and being coaxially aligned with one another for receiving openings in a joint part to pivotably connect the joint part with said second piece.
A method of making a windscreen wiper device, comprising the steps of:
- operably connecting at least one longitudinal strip with an elastomeric wiper strip to bias the wiper strip into a pre-curved condition;
- permanently attaching a first and second pieces together to form a base;
- operably connecting the first piece of the base with the at least one longitudinal strip;
- wherein the second piece of the base has a pair of laterally spaced apart side walls that are each J-shaped;
- and
- operably connecting a joint part with the second piece of the base such that the joint part is pivotable relative to the base.
