They are less bulky than over-the-shoulder harnesses (which they have replaced on some Bolliger & Mabillard roller coasters) and the thinner vest reduces headbanging. However, they fit tighter than an over-the-shoulder restraint, which can feel more restrictive.
Design[edit | edit source]
The harness consists of a rigid lap-bar that closes from above, with a flexible "vest" attached that restricts the upper body, leaving arms free. A seat belt is fastened between the bottom of the restraint and the front of the seat.
History[edit | edit source]
Vest harnesses were first used as part of the restraint system on the Bolliger & Mabillard Flying Coaster product. The prototype, Air, opened at Alton Towers in 2002. The vest harness is used alongside shin restraints to hold riders in a flying position.
The first non-flying roller coaster to use vest harnesses is Raptor, which opened at Gardaland in 2011. It is also the first Wing Coaster - all Wing Coaster installations use vest harnesses. Since this time, some B&M roller coasters have used vest harnesses while others have used the older over-the-shoulder harnesses.
