Abstract:
1. A vehicle pop-up hood apparatus comprising: an arm member, of which a proximal end portion is connected to a body of a vehicle via a bracket so as to be pivotable about a first axis extending in a width direction of the vehicle; a connection mechanism by which a hood of the vehicle is integrally connected to a tip side portion of the arm member, and that allows the hood to pivot relative to the arm member about a second axis extending in the width direction of the vehicle, and to move relative to the arm member in a longitudinal direction of the vehicle when an integrative connection between the arm member and the hood is broken; an actuator that breaks the integrative connection, established by means of the connection mechanism, between the hood and the arm member, and that generates a lifting force that lifts the hood relative to the body, the connection mechanism includes a deformation portion by which the arm member and the hood are integrally connected with each other, and that breaks the integrative connection between the arm member and the hood by being plastically deformed by the lifting force generated by the actuator; a first restriction mechanism that restricts an angle of pivotal movement of the arm member relative to the body to a predetermined angle at a connection portion at which the proximal end portion of the arm member and the body are connected, the first restriction mechanism including a contact tab and a stopper; a second restriction mechanism that, when the hood is lifted by the lifting force, stops an ascent of the hood so that the stopper of the first restriction mechanism does not contact the contact tab; and a third restriction mechanism having a first portion formed on the arm member and a second portion connected to the hood, wherein the contact tab of the first restriction mechanism is formed at the proximal end portion of the arm member, the stopper of the first restriction mechanism is formed at a proximal end portion of the bracket, the first axis being a pivotal axis extending through both the arm member with the contact tab and the bracket with the stopper, and the second restriction mechanism is formed at a distal end portion of the arm member such that the contact tab is in proximity to the stopper of the first restriction mechanism.
