  • Patent number: 11260731
    Abstract: A vehicle door assembly includes an inner door panel that partially defines a cavity therein, a door handle assembly, a main reinforcing bracket, a first reinforcing bracket and a vibration absorbing member. The first reinforcing bracket has an upper end fixedly attached to the main reinforcing bracket and to a rearward area of the inner door panel within the cavity below the door handle assembly. The vibration absorbing member has an outboard surface, an inboard surface and a main projection that extends forward from the main body. The main projection is fixed to the first reinforcing bracket such that the main body is rearward of the first reinforcing bracket. The outboard surface is shaped and dimensioned to correspond to the overall shape of the inboard portion of the door handle assembly.

  • Patent number: 8232476
    Abstract: It is an object of the present invention to provide a flexible multilayer wiring board that can be easily reduced in thickness and that also has sufficient durability against repeated bending or heat shock. A preferred mode of the flexible multilayer wiring board comprises a flexible inner layer board obtained by forming an inner layer wiring on both sides of an insulating layer, an outer layer wiring situated on at least one side of the inner layer board, and insulating adhesive sheets lying between the inner layer board and outer layer wiring. One of the insulating adhesive sheets are composed of an imide group-containing polymer.
