Stability of shock absorbing property of a shock absorber provided on a back surface of a door trim is improved. A shock absorber is attached on the back surface of the door trim, and absorbs impact applied to the door. A quadrangular tube element of the shock absorber has an end plate on a tube tip surface, and faces the back surface of the door trim. The quadrangular tube element has an approximate U shape in which three side surfaces are closed by an upper plate, a lower plate, and a front plate, and the remaining one side surface is opened.

A mounting structure for mounting an interior component to a door trim body includes: a rear locking protrusion including a first portion protruding from a back surface of the interior component and a second portion extending from a distal end of the first portion toward a front of a vehicle; a rear mounting hole in a rear edge section of the door trim body and opposed to the rear locking protrusion; a locking protrusion protruding from the back surface toward the door trim body and is disposed closer to a front of the vehicle relative to the rear locking protrusion; and a mounting hole in a section of the door trim body at a position closer to the front relative to the rear mounting hole and opposed to the locking protrusion. The second portion of rear locking protrusion is locked to a hole edge of the rear mounting hole.

An upper reinforcement for a door trim panel includes a reinforcement channel, softening features within reinforcement channel, a tab depending from the reinforcement channel, and a trigger feature between the reinforcement channel and the tab whereby the reinforcement channel is released from the tab during a side impact. A method of tuning performance characteristics of the upper reinforcement is also described.

A vehicle door assembly a first reinforcing bracket, a fastener and a vibration absorbing member. The first reinforcing bracket extends from a forward portion of an inner door panel to a rearward portion of the inner door panel. The first reinforcing bracket has a first main surface. The fastener is attached to the first reinforcing member such that a head portion thereof is spaced apart from of the first main surface. The vibration absorbing member has a main body with a first end and a second end. The first end has a slot that extends from an edge of the first end inward. The slot is dimensioned and shaped for sliding installation on to the fastener such that the first end of the vibration absorbing member is located between the head portion of the fastener and the first surface of the first reinforcing bracket.

A door assembly includes a door and a pusher. The door defines a cavity. The pusher is fixed to the door in the cavity, and the pusher contains a non-Newtonian fluid. The door assembly may be installed in a vehicle. Because the pusher contains a non-Newtonian fluid, the pusher distributes force from the impact to an occupant in a manner that depends on a size of the occupant.

An impact absorber to be mounted on a vehicular exterior side surface of a vehicular interior part covering a vehicular panel from a vehicular interior side includes an opposite wall to be opposite the vehicular panel, outer walls extending from edges of the opposite wall toward a vehicular interior side, and mounting portions that are to be fit to mount members included on the vehicular exterior side surface of the vehicular interior part, each of the mounting portions including a basal portion being included at a vehicular interior side end of one of the outer walls and in contact with the vehicular exterior side surface of the vehicular interior part, a distal end portion being on a vehicular exterior side than the basal portion and to be secured to one of the mount members, and an intermediate portion connecting the basal portion and the distal end portion.

An upper reinforcement for a door trim panel includes a reinforcement channel, softening features within reinforcement channel, a tab depending from the reinforcement channel, and a trigger feature between the reinforcement channel and the tab whereby the reinforcement channel is released from the tab during a side impact. A method of tuning performance characteristics of the upper reinforcement is also described.

There is provided a vehicle body structure including: a seat member storable in a floor of a vehicle body; a front door disposed on a vehicle-width directional outer side relative to the seat member; a first load transmission member and a second load transmission member disposed in the front door and configured to transmit a side collision load to the seat member at a side collision. The first load transmission member and the second load transmission member are arranged higher than an upper surface of the seat member being in a dive-down stored condition.

A door-trim panel for a vehicle includes an armrest and a top roll extending upwardly from the armrest to an upper end. The upper end has an inboard portion and an outboard portion and the upper end is elongated along a longitudinal axis. The top roll includes pairs of ribs spaced from each other along the longitudinal axis. The pairs of ribs include an inboard rib extending from the inboard portion toward the outboard portion to an outboard end. The pairs of ribs include an outboard rib adjacent to and spaced from the inboard rib of that pair. The outboard rib extends from the outboard portion toward the inboard portion to an inboard end of the outboard rib. The inboard ribs and outboard ribs are elongated transverse to the longitudinal axis. The inboard end and the outboard end are spaced from the inboard portion of the top roll.

A shock absorbing structure of a vehicle door including a vehicle body panel with a service hole includes a door trim and a shock absorber. The door trim covers the vehicle body panel from an interior side of a vehicle. The shock absorber is mounted to the vehicle body panel to cover the service hole. The shock absorber includes a shock absorbing portion that is inserted in the service hole. The shock absorbing portion is disposed such that an end of the shock absorbing portion on an exterior side of the vehicle is disposed more to the exterior side of the vehicle than the service hole and between the vehicle body panel and the door trim.
