A passenger seating installation for a vehicle comprises a front seat located adjacent a bulkhead and facing in a direction that is oblique to the direction of travel of the vehicle. The bulkhead includes a recess for receiving the head of a passenger in the front seat in the event of an accident. The recess is spaced apart from the front seat in the direction of travel and in a direction that is obliquely disposed with respect to the direction in which the seated passenger faces. The recess allows the front seat to be located closer to the bulkhead than would be the case in the absence of the recess, which can increase seat density in a seating area.
