UPDATE 1-Ferrari's son to buy stake in Pininfarina

(Adds Marsiaj family name, background)

MILAN, April 29 (Reuters) - Pininfarina PNNI.MI said on Tuesday the son of the founder of sports car maker Ferrari FIA.MI will be among key figures buying shares in the car designer and contract manufacturer as it seeks to raise capital.

Piero Ferrari will be one of three prominent figures of the Italian automotive industry who will be taking stakes, a spokesman said.

The others are Alberto Bombassei, chairman of braking systems maker Brembo BRBI.MI and the Marsiaj family, founders of seatbelt maker Sabelt, he said.

Bombassei had hinted at his participation in the capital increase when speaking to reporters at a corporate event on Monday.

Pininfarina wants to raise 100 million euros through a capital increase by the middle of the year to finance a restructuring plan to revive its struggling business.

Chief Executive Andrea Pininfarina disclosed the names of those planning to take part at the company’s annual shareholders meeting at its offices near the industrial city of Turin in northern Italy, the spokesman said.

The three Italian names were the last ones that had been awaited by the market after French financier Vincent Bollore and Indian industrialist Ratan Tata confirmed their participation.

Pininfarina will use part of the proceeds to pay for an electric car that it is developing with Bollore. The car is a pivotal part of Pininfarina’s restructuring.

Pininfarina’s founding family of the same name has a 55 percent stake, but it is prepared to reduce it to allow these investors to enter the company. It will still keep a controlling stake of more than 30 percent. (Reporting by Gilles Castonguay; editing by Elaine Hardcastle)
