专利汇可以提供Windshield wiper assembly专利检索，专利查询，专利分析的服务。并且A windshield wiper arm assembly oscillatably supported from a marginal edge portion of a windshield for angular displacement of approximately 90* between a retracted position closely adjacent and generally paralleling the windshield marginal edge portion and an extended position projecting inwardly of the marginal edge portion with the arm overlying the windshield glass. A first motor assembly is provided for selectively swinging the support arm between its retracted and extended operative position and a rotary blade equipped wiper head is journaled from the free end of the support arm. A second motor assembly is provided and drivingly coupled to the rotary head through a drive shaft journaled through the support arm and is operative to rotate the blade equipped head when the support arm is in its extended operative position. Also, the rotary head is provided with at least one generally radially extending blade which may be positioned in closely adjacent parallel relation to the support arm when the latter is being swung toward and is disposed in its retracted position generally paralleling and closely adjacent the aforementioned marginal edge portion of the associated windshield assembly.，下面是Windshield wiper assembly专利的具体信息内容。

权利要求

1. A windshield wiper assembly comprising a wiper arm having base and free ends, a rotary head journaled from said free end and including generally radially outwardly extending elongated wiper blade portions, a rotary drive shaft journaled from and extending longitudinally of said arm and having its end adjacent said head drivingly coupled thereto, a first drive wheel carried by the other end of said drive shaft, a support, means mounting the base end of said arm from said support for oscillation about an axis extending transversely of said arm, a driven shaft journaled from said support and having a driven wheel mounted thereon, said arm being oscillatable about said axis between a first retracted position and a second extended operational position, said drive wheel, upon movement of said arm from said first position to said second position, being swung from an inoperative position out of drive connection with said driven wheel to an operative position with said driven wheel engaged with and drivingly coupled to said drive wheel.

2. The combination of claim 1 wherein said head and the radial innermost ends of said blade portions include means swingably supporting said block portions from said head for swinging movement toward inoperative positions generally paralleling and disposed alongside the free end of said arm.

3. The combination of claim 1 wherein said support is adapted for securement to a vehicle body portion adjacent one marginal edge portion of a window of said vehicle, the first mentioned means including means swivelly mounting said base end from said support and bias means yieldingly biasing said base end toward a predetermined rest position of swivel adjustment independent of displacement of said base end about its axis of oscillation relative to said support.

4. The combination of claim 3 wherein said arm and support include means operative to cam said arm in a predetermined lateral direction against the action of said bias means as said arm completes its movement toward said second position.

5. The combination of claim 1 wherein said support is adapted for securement to a vehicle body portion adjacent one marginal edge portion of a window of said vehicle, the first mentioned means including means swivelly mounting said base end from said support and bias means yieldingly biasing said base end toward a predetermined rest position of swivel adjustment independent of displacement of said base end about its axis of oscillation relaTive to said support, motor means drivingly connected between said support and said arm for swinging the latter between said first and second positions.

6. A windshield wiper assembly comprising a wiper arm having base and free ends, a rotary head journaled from said free end and including generally radially outwardly extending elongated wiper blade portions spaced thereabout, a support, means mounting the base end of said arm on said support for oscillation about an axis extending transversely of said arm, the inner ends of said blade portions including short elongated articulated segments pivotally secured at one set of corresponding ends to said head and to said blade portions at the other set of corresponding ends, said articulated segments being sufficient in length to allow all of said blade portions to swing toward positions closely adjacent and in side-by-side relation with the free end portion of said arm.

7. The combination of claim 6 wherein said support is adapted for securement to a vehicle body portion adjacent one marginal edge portion of a window of said vehicle, the first mentioned means including means swivelly mounting said base end from said support and bias means yieldingly biasing said base end toward a predetermined rest position of swivel adjustment independent of displacement of said base end about its axis of oscillation relative to said support.

8. The combination of claim 7 wherein said arm and support include means operative to cam said arm in a predetermined lateral direction against the action of said bias means as said arm completes its movement toward said second position.

9. The combination of claim 1 wherein the inner ends of said blade portions include short elongated articulated segments pivotally secured at one set of corresponding ends to said head and to said blade portions at the other set of corresponding ends, said articulated segments being sufficient in length to allow all of said blade portions to swing toward positions closely adjacent and in side-by-side relation with the free end portion of said arm.

10. A windshield wiper assembly comprising a wiper arm having base and free ends, blade means carried by said free end, a support, means mounting the base end of said arm from said support for oscillation about an axis extending transversely of said arm, said support being adapted for securement to a vehicle body portion adjacent one marginal edge portion of a window of said vehicle, the first mentioned means including means swivelly mounting said base end from said support and bias means yieldingly biasing said base end toward a predetermined rest position of swivel adjustment independent of displacement of said base end about its axis of oscillation relative to said support.

11. The combination of claim 10 wherein said arm and support include means operative to cam said arm in a predetermined lateral direction generally paralleling said axis against the action of said bias means as said arm is moved toward one limit position of oscillation.
