Takata Corp. is considering bankruptcy protection for its U.S. unit, among other options, a person with knowledge of the matter said.

The Tokyo-based firm's defective air bag inflators have led to the biggest recall in auto industry history.

The company hired Weil Gotshal & Manges LLP to help weigh options that could include bankruptcy or a sale, according to people with knowledge of the matter. The air bag maker said no decision has been made.
