Abstract
Methods and apparatus are provided for a mounting system adapted to attenuate a shock load imparted by a structure to an object being supported by the structure. In one exemplary embodiment the mounting system comprises a mounting plate with a perimeter portion, a central boss, and an array of at least two symmetrically arranged perforations extending through the mounting plate between the perimeter portion and the central boss. The perforations are arranged so as to cooperatively define at least two deformable links that interconnect the central boss with the perimeter portion of the mounting plate, wherein the deformable links are adapted to attenuate the shock load through plastic deformation.
Claims16
A vehicle seat mounting system for attenuating a severe shock load imparted to the seat by the vehicle structure, the mounting system comprising:
- a mounting plate with a perimeter portion connected to one of the seat and the vehicle structure, wherein a space is provided between the mounting plate and a seat occupant supporting surface to allow for deformation of the mounting plate towards the seat occupant supporting surface;
- a central boss connected to the other of the seat and vehicle structure;
- and
- an array of at least two symmetrically arranged perforations extending through the mounting plate between the perimeter portion and the central boss arranged so as to cooperatively define at least two deformable links that interconnect the central boss with the perimeter portion of the mounting plate, wherein the deformable links are adapted to attenuate the shock load through plastic deformation.
A vehicle seat mounting system for attenuating shock loads imparted to the seat by the vehicle, the mounting system comprising:
- a mounting plate with a perimeter portion connected to the vehicle structure;
- a central boss connected to a seat frame;
- an array of at least two symmetrically arranged perforations extending through the mounting plate between the perimeter portion and the central boss, the perforations arranged so as to cooperatively define at least two deformable links that interconnect the central boss with the perimeter portion of the mounting plate, wherein the deformable links are adapted to attenuate the shock load through plastic deformation;
- and
- a first spacer between the perimeter portion of the mounting plate and the vehicle structure, wherein the mounting plate is connected to the spacer, and the spacer is connected to the vehicle structure, the spacer providing clearance for the mounting plate to plastically deform.
