HAMBURG, West Germany (AP) _ Brigitte Horney, one of West Germany's best-known television, stage and movie actresses and the daughter of psychiatrist Karen Horney, died Wednesday at the age of 77.

Horney, star of such German films as ''Savoy Hotel 217'' who was famous for her sultry voice, died of heart failure, according to the New German Film Company.

Earlier this summer, she had portrayed a countess in the West German TV series, ''The Guldenburgs' Heir.'' In 1980, she appeared as Aunt Polly in a German version of Mark Twain's ''Tom Sawyer and Huckleberry Finn.''

The actress was born in Berlin on March 29, 1911, and landed her first film role at age 19 in the 1930 movie ''Abschied'' or ''Farewell.''

Later, she appeared in plays at the City Theater in Wuerzburg and the German Theater Berlin.

She also appeared in the British films ''Secret Life'' and ''The House of the Spaniard.''

Horney moved to Switzerland just before the end of World War II. After the war, she returned to West Germany and to the stage, appearing in plays by Max Frisch, Jean-Paul Sartre and others.

Her mother, who died in 1952, was known for her unorthodox approach to Freudian analysis.
