Abstract

A knee panel for a front seat of a vehicle, located under an instrument panel for protecting a driver and a passenger riding on the front seat, and a knee panel mounting structure which minimizes the deformation and displacement of the knee panel and its supporting member, when the driver'"'"'s and/or passenger'"'"'s knees make contact with the inner surface of the knee panel, by bearing the impact force on a front pillar side through a side bracket and on a floor side thereof through an L-shaped bracket, thereby directing the impact force as a load toward both the ends of the L-shaped bracket.

Claims

1. A knee panel for a front seat of a vehicle, comprising:

(a) a substantially horizontally extending panel element, having a substantially convex shape when viewed in a longitudinal cross section of the vehicle, the convex outer surface of said element facing the front seat of the vehicle in the rearward direction of the vehicle, said panel element being securely fixed at an upper portion thereof to the lower portion of an instrument panel of the vehicle;

of an instrument panel of the vehicle;

(b) a substantially horizontally extending, substantially rigid one-piece reinforcing member substantially longitudinally coextensive with said panel element, said reinforcing member having substantially a dish shape when viewed in a longitudinal cross section of the vehicle, said reinforcing member being securely fixed at its peripheral edges to the lower inner surface of said panel element; and

(c) a knee panel mounting structure comprising,

(i) a side bracket securely fixing and supporting said knee panel element at the outer side end of the lower edge thereof;

(ii) an L-shaped bracket having horizontal and vertical mounting portions, said horizontal mounting portion of said L-shaped bracket being securely fixed to the inner side end of the lower edge of said knee panel element;

(iii) a floor bracket attached to the floor of the vehicle at a center line portion thereof; and

(iv) a center line brace attached to said floor bracket, said center line brace being securely fixed to said vertical mounting portion of said L-shaped bracket,

said reinforcing member and said knee panel mounting structure cooperating to provide substantially rigid support to said knee panel element so that local deformation of said knee panel element upon impact with the knees of vehicle occupants is eliminated and the movement of the vehicle occupants'"'"' knees upon impact with the knee panel is thereby restricted.

2. The knee panel of claim 1, wherein said reinforcing member is perforated with a plurality of openings;

3. The knee panel of claim 1, wherein said knee panel mounting structure further comprises a reinforcement member of the instrument panel of the vehicle securely fixed to said knee panel element at the upper mounting portions thereof, said upper mounting portions of said knee panel element being in the vicinity of both upper edges thereof.

4. The knee panel of claim 2, wherein said knee panel element is coated with a buffer material and a vinyl chloride resin skin.
