The invention relates to a motor vehicle seat () having an upholstered component () which is covered by flexible covering (), and a safety device which is arranged in the upholstered component () and has an airbag () which is coupled to a gas generator (). The gas generator () is activated when sensor data relating to an accident or an imminent accident are present to inflate the airbag () with gas and unfold the airbag. An activator () is provided by means of which the airbag () or separate gas cushion () can be additionally repeatedly inflated with gas in a reversible fashion. The covering () is of an inelastic design, at least in certain areas, and has an elastic section () which is arranged in the covering ().

Motor vehicle seat

A safety arrangement () is located beneath the hood or bonnet () of a motor vehicle and includes an inflatable element () which is formed of a plastically deformable material. A gas generator () supplies gas to inflate the element () in response to a signal from a sensor () which is responsive to impact with a pedestrian. The gas generator () passes gas to a chamber (), and thus through a relatively small aperture () to inflate the element () with a gradual inflation. If a pedestrian strikes the bonnet, the pedestrian will not deform the bonnet and then be arrested by impact with an engine block or the like, and also the plastically deformable element () will deform to absorb energy.
