Abstract: The invention concerns a method and an apparatus for mechanical stimulation in vitro of tissue, wherein tissue patches (1) are retained in a tissue carrier (2), thereby presenting first surfaces (3) to be stimulated in a plane (X) and wherein a roller (4) having a second surface (5) arranged at its periphery is moved parallel to said plane (X), thereby imposing selected forces on said first surfaces (3) by said second surface (5) for stimulating the tissue patches (1). By presenting the surfaces (3) to be stimulated in a common plane (X) and by moving the roller (4) parallel to said common plane (X) of the first surfaces (3), serving several tissue carriers (2) with one roller (4) is made easy, thus integration into an industrial production is made practicable.

Abstract: A seat component to prevent whiplash injury during a rapid motion change of a vehicle comprises means allowing a displacement of the seat and a person sitting thereon backwards (22) in relation to the direction of movement at the motion change. These means comprise a body (11, 18) to be affixed to or being part of the seat, a slide element (16) affixed to the vehicle and being in guiding contact with said body to guide a translational displacement of the seat over a predetermined distance. It further comprises a trigger system (13) to detect a acceleration threshold, a release mechanism (14) controlled through the trigger system (13) to enable said translational displacement (22) and a damping component (17) to damp said translational displacement (22). The trigger system (13) opens the release mechanism (14) only upon detection of an acceleration value above a predetermined threshold.
