ABSTRACT:
A personal support device having particular utility for use by personnel in high-performance surface watercraft comprises a bolster adapted and dimensioned to support an occupant for shock isolation from accelerations experienced by the vessel. The bolster is mounted by pivot means extending between the bolster and a back plate which is rigidly mounted to the vessel. The pivot means permit the bolster to pivot in an arc with respect to the back plate. A shock absorber extends between the back plate and bolster to dampen the accelerations which would otherwise be passed to the bolster by the pivot means from the back plate. The bolster is capable of supporting a user in a standing position or receiving a seat assembly to allow an occupant to be seated.
