Abstract

A hinge for a vehicle hood is provided. The hinge includes a hinge lower fixed to a vehicle body, and a hinge upper fixed to the hood and rotatably supported relative to the hinge lower. The hinge upper includes a first member rotatably supported relative to the hinge lower, and a second member fixed to the hood and relatively movable relative to the first member. The hinge further includes a first lock configured to be engageable with the first member to restrict rotation of the first member relative to the hinge lower. The first member and the second member are integrally rotatable relative to the hinge lower in a normal operation of opening and closing the hood. When the hood is caused to pop up, the first lock engages with the first member and the second member is relatively movable relative to the first member.

First claim

What is claimed is:

1. A hinge for a hood of a vehicle, the hinge comprising:
a hinge lower fixed to a vehicle body; and
a hinge upper fixed to the hood and configured to be rotatably supported relative to the hinge lower,
wherein the hinge upper comprises:
a first member rotatably supported relative to the hinge lower; and
a second member fixed to the hood and configured to be supported so as to be relatively movable relative to the first member,

wherein the hinge further comprises:
a first lock configured to be engageable with the first member to restrict rotation of the first member relative to the hinge lower,
a second lock provided on the second member, and
a linkage member connecting the first member and the second member,

wherein an actuator relatively moves the second member relative to the first member when the hood is caused to pop up,
wherein the first lock has a first slide portion on which the actuator abuts and slides,
wherein the second lock has a second slide portion on which the actuator abuts and slides,
wherein in the normal operation of opening and closing the hood, the second lock engages with the first member to inhibit relative movement between the first member and the second member, so that the first member and the second member are integrally rotatable relative to the hinge lower,
wherein when the hood is caused to pop up, the actuator pushes the second slide portion of the second lock to disengage the second lock from the first member and the actuator pushes the first slide portion of the first lock, so that the first lock engages with the first member and the second member is relatively movable relative to the first member, and
wherein when the hood is caused to pop up, a claw portion formed on the linkage member is inserted into an opening formed in the first member by which the linkage member is rotatably supported, so that the linkage member and the first member are engaged with each other to thereby restrict a rotation range of the linkage member.

2. The hinge according to claim 1 , wherein one end portion of the first member is rotatably supported relative to the hinge lower, and
wherein the first lock is engageable with another end portion of the first member.

3. The hinge according to claim 1 , wherein the other one of the first member and the second member has a recess or a projection at a position engageable with the second lock.

4. The hinge according to claim 1 , wherein that portion of the other one of the first member and the second member which engages with the second lock is a pin portion, and
wherein a diameter of the pin portion changes in an axial direction of the pin portion.
