Abstract: In a forward engine compartment of a vehicle a power unit is suspended so as to have a controlled rearward movement in the engine compartment when exposed to excessive forces in the lengthwise direction of the vehicle during a collision. There is at least one rear mounting having a resilient body separating two members secured to the power unit and to structural portions of the vehicle body, respectively. Said rear mounting allows one of the members a limited movement relative to the other while absorbing deformation work. As the power unit travels further back the attachment of the rear mounting is gradually destroyed, but it holds long enough to allow the power unit to hit a cowl panel at the rear of the engine compartment, thus controlling the travel of the power unit.

Abstract: A clamp for an elongated cylindrical workpiece such as a hose or pipe, comprises two, substantially identical, clamp members each having a semi-cylindrical recess formed therein. A cylindrical elastic insert is fitted around the workpiece and then inserted into the circular recess formed when the two clamp members are fastened one to the other. In the axial direction, the elastic insert has an elevated central region which engages a similar, depressed central region in the cylindrical recess formed by two clamp members. The height of the depressed region is less than the height of the elevated region; thus, while the workpiece is totally restrained from axial motion, in the region where the workpiece enters or exits the clamp, a limited amount of bending is permitted, thus avoiding stress and possible damage to the workpiece.

The backing and plastisol resin are heated, the heat causing the plastisol resin to change into a solid cushion layer, bonded to the backing.

Abstract: Angular vibration isolation is provided for a seat back member in combination with a mechanism for adjusting the seat back angle. Eccentrically mounted cylindrically shaped cam members located at each side of the seat back frame can be adjustably rotated within a guide channel carried by the seat back frame. The cams are positioned at a distance from a pivot axis on the seat frame around which the seat back can tilt in order to adjust the angle of tilt. One of the parallel, opposed flanges which define each of the guide channels is spaced from its respective cam member by a resilient means such as a thick pad of elastomeric material which fills the space between the cam member and said one flange. The elastomeric pads are compressed as the seat back is forced forwardly against the seat occupant's back due to vehicle vibration, thus permitting the seat back to be driven rearwardly while the occupant's position in space remains relatively fixed.
