Mounting bracket for a covering for architectural openings

1. A mounting bracket for mounting a head rail of a covering for architectural openings onto a surface, comprising:

a first substantially rigid L-shaped body defining an inner surface and an outer surface and including a horizontal leg and a vertical leg projecting downwardly from said horizontal leg, said horizontal leg defining a forward lip and a rearward shoulder for releasably securing the head rail to said body portion, said L-shaped body portion also defining an upwardly-directed shoulder; and

a clip which is substantially more flexible than said L-shaped body, said clip having a horizontal portion supported on said upwardly-directed shoulder; and an angled portion having an “at rest” position in which it extends at an angle that is forward and downward relative to said vertical leg and having a “flexed” position in which it extends at an angle that is downward and rearward relative to its “at rest” position; said angled portion including a lower end having at least one forwardly-directed projection for receiving the bottom of the head rail.

2. A mounting bracket for mounting a head rail onto a surface as recited in claim 1 , wherein the body portion is a plastic part and the clip portion is a metal part.

3. A mounting bracket for mounting a head rail onto a surface as recited in claim 2 , wherein said clip also includes a vertical portion that lies adjacent to the inner surface of said vertical leg.

4. A mounting bracket for mounting a head rail onto a surface as recited in claim 3 , wherein said vertical portion of said clip includes first and second vertical tines in the upper portion of said clip; and wherein said housing defines vertical slots which receive said tines.

5. A mounting bracket for mounting a head rail onto a surface as recited in claim 3 , wherein said clip includes a hook which wraps around said upwardly directed shoulder, and wherein a portion of said hook is vertical.

6. A mounting bracket for mounting a head rail onto a surface, comprising:

a first substantially rigid L-shaped body defining an inner surface and an outer surface and including a horizontal leg and a vertical leg projecting downwardly from said horizontal leg, said horizontal leg defining a forward lip and a rearward shoulder for releasably securing the head rail to said body portion, said L-shaped body portion also defining an upwardly-directed shoulder; and

a clip which is substantially more flexible than said L-shaped body, said clip having a horizontal portion supported on said upwardly-directed shoulder; an angled portion extending at a forward angle to said vertical leg; and a lower end having at least one forwardly-directed projection for receiving the bottom of the head rail, wherein the body portion is a plastic part and the clip portion is a metal part, and further comprising a beam-strengthening insert secured to the horizontal leg of said L-shaped body, said insert including at least one flat portion and one linear flange portion connected to said flat portion via a web.

7. A mounting bracket for mounting a head rail onto a surface as recited in claim 6 , wherein said web lies along a plane which is substantially perpendicular to the plane defined by said flat portion of said insert.
