DETROIT, Aug 4 (Reuters) - TRW Automotive Holdings Corp (TRW.N) posted a quarterly loss on Tuesday due to production cuts at automaker customers, but the results topped Wall Street forecasts, and its shares jumped as much as 19 percent to their highest level in almost a year.

The vehicle parts maker, whose products include safety equipment such as seat belts and airbags, raised its 2009 revenue forecast and said it was confident that the auto industry had hit bottom.

"We remain optimistic the first half of 2009 was the trough in global automotive production for the current downturn," Chief Executive John Plant said in a statement. "Vehicle production forecasts are indicating higher levels of production for the remainder of 2009 and into 2010."

TRW's outlook follows similar statements of confidence from auto and parts makers in the past few days that the industry found a bottom earlier in 2009.

The net loss came to $11 million, or 11 cents per share, in the second quarter, compared with a year-earlier profit of $127 million, or $1.24 per share.

Excluding restructuring and impairment charges and a gain on debt retirement, TRW reported earnings of 8 cents per share. Analysts on average expected a loss of 83 cents on that basis, according to Reuters Estimates.

"This performance serves to highlight just how much cost has been taken out of the business over the past three or four quarters," JPMorgan analyst Himanshu Patel said in a note.

Revenue fell 38.6 percent to $2.73 billion, while analysts were expecting $2.58 billion. Sales were pressured in all regions due to sharply reduced vehicle production volumes.

Auto parts suppliers have suffered from steep production cuts this year by all major automakers, with U.S. auto sales down about 35 percent through the first half of 2009 to their lowest rates since the early 1980s.

The parts sector was dealt a further blow in recent months from extensive plant shutdowns associated with the bankruptcies of General Motors [GM.UL] and Chrysler. TRW said those bankruptcies had minimum impact on the company.

Automakers posted their best U.S. sales of the year in July, supported by the government "Cash for Clunkers" program that started in the last week of the month.
