Does a search at the scene of a robbery occur when the car is searched later at the police station?

In Chambers v. Maroney, supra, police stopped a vehicle based on eyewitness descriptions of robbers and their getaway car. The occupants were arrested, but the car was not searched at the scene. Instead, it was driven to the police station where a later search revealed weapons and incriminating evidence hidden under the dashboard. Affirming a denial of federal habeas corpus after convictions of robbery, the high court held that a search--reasonable at the time and place the car was stopped--does not become unreasonable because conducted later at the police station.
