Abstract

PROBLEM TO BE SOLVED: To provide a vehicle door handle which prevents opening of doors in the event of lateral impact on a vehicle, not only on the side of impact but also the opposite side of the impact. SOLUTION: The vehicle door handle is comprised of a transmission lever 21, an inertial member 39, an inertial mass 42, and a one-way angular locking device 57. The transmission lever 21 is activated from the outside by means of a control member 16 to rotate about a hinge axis 15, between an angular rest position and an angular work position to open a lock on the door. The internal member 39 keeps the transmission lever 21 in the rest position in the event of lateral impact on the vehicle, and rotates about the axis 15 with respect to the transmission lever 21. The inertial mass 42 is located eccentrically with respect to the first axis 15. The locking device 57 enables the mass 42 to rotate, together with the transmission lever 21, in one rotation direction, so as to exert a balancing force in the one rotation direction, so as to balance the inertial forces tending to move the lever 21 into the work position in the event of lateral impact, and so as to freely rotate with respect to the lever in the opposite direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a vehicle door handle.

Rotated between a non-operating position held by a return spring preloaded and an operating position to open the door lock using a transmission lever interposed between the manual operation lever and the door lock. Handles with manual levers are well known. Also, known handles are usually provided with a safety device to prevent the door lock from opening, especially when the load pre-loaded on the return spring is limited to reduce the effort to open the lock. When a collision accident occurs, the door is prevented from opening naturally.

In particular, inertial safety devices (inertial safety de
As the vices, those having a mass, that is, a weight, which is formed integrally with the transmission lever and is eccentric with respect to the rotation axis of the transmission lever are used.

[0004] With the known type of handle described above, the known inertial device is disadvantageous in that it only keeps the broken door closed and the opposite door is left open freely. .

That is, in a handle of the type described above, the mass of the broken door handle generates a moment of inertia on each lever so as to hold the lever in the non-operating position, whereas the other door handle has a moment of inertia. The mass rotates each transmission lever and releases the lock.

[0006] It is an object of the present invention to provide a vehicle door handle designed to directly and economically solve the above problems.

According to the present invention, a transmission externally operated using an operating member to rotate about a first axis between an angularly inoperative position and an angularly operating position for opening a door lock. A lever and holding means for holding the lever in a non-operating position when struck against the side of the vehicle, the holding means being coupled to the lever and being impacted laterally against each door. A door handle for a vehicle including an inertial mass body disposed eccentrically with respect to a first axis so as to exert a balancing force for balancing an inertial force for moving the lever to an operating position when the lever is moved. , The mass rotates about the second axis about the lever and the retaining means locks one of the angular orientations interposed between the mass and the lever so as to fix the mass in the angular orientation with respect to the lever. Comprising a ring means, by applying a force balance in one rotational direction, and to provide a vehicle door handle, characterized in that freely rotate relative to the lever the masses in opposite directions.

Hereinafter, embodiments which do not limit the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 in FIG. 1 indicates a part of a handle for operating a vehicle door lock. The handle 1 is provided with a structure 2 integrally formed with a door (not shown) on the side of the vehicle by a known method, the detailed description of which is omitted here.

The structure 2 has an intermediate portion 8 and a hollow end portion 9 which extend longitudinally and are adjacent to each other when attached to each door. The part 9 and the part 8 have respective side appendages 10 having respective through holes 12, 13 extending coaxially along a longitudinal axis 15 with respect to each other.
Support 11

Referring to FIG. 1, the handle 1 is
An external operation lever 16 is provided. This lever is gripped by an operator (not shown) opening the respective lock, hinged to the structure 2 (not shown) in a well-known manner, and supports the end arm 18. . The arm 18 engages the part 9 and supports teeth 19 extending in the direction of the part 8 parallel to the axis 15 at the end of the part 9.

As shown in FIGS. 1 and 2, and especially in FIG.
The handle 1 comprises a C-shaped transmission lever 21 substantially partially enclosed within the part 9, and in turn comprises a part 23 slidably cooperating with the teeth 19,
Pins 24 are engaged with holes 12 and 13 and extend through tubular body 27 disposed between appendages 10 and 11 and are hingedly attached to appendages 10 and 11 by pins 24 integrally formed with lever 21. It has one end.

The pin 24 causes the lever 21 to move
Can be rotated about axis 15 between the angularly non-operating position and the angularly operative position shown in FIG. 1 so as to unlock the respective doors when actuated by the operator.

A preloaded torsion spring 28 inserted between the lever 21 and the structure 2 is wound around the tubular body 27 so as to elastically return the lever 21 to the non-operating position. I have.

As shown in the accompanying drawings, the handle 1 holds the lever 21 in a non-operating position in the angular direction, and releases the lock when the vehicle collides from the side to prevent the lever from opening naturally. Safety holding member 3 connected to 21
9 is provided.

The member 39 is formed as one piece and has a hollow bottom portion 40 surrounding the accessory 10 and a part of the lever 21.
And is hinged to the accessory 10 by a pin 24 so as to rotate about the axis 15 with respect to the lever 21. A plate-like arm 41 extends radially outward from the bottom part 40 and is substantially parallel to the lever 21 and
1 supports a cylindrical mass or weight 42 which is displaced in the axial direction with respect to 1 and extends longitudinally at the free end opposite the arm 41.

The member 39 has a stop member 52,
The stop member is arranged between the shaft 15 and the mass 42, and is particularly formed integrally with the arm 41 and the bottom portion 40, and is parallel to the shaft 15 and positioned from the arm 41 at a position facing the side surface 53 of the lever 21. An appendage 55 is formed at the distal end that projects and is formed to support the arm 56 of the spring 28 of FIG.

In actual use, when there is no side collision, the spring 28 holds the lever 21 in the non-operating position, and the stop member 52 controls the side 5 of each lever 21.
3 abuts on the middle part.

On the other hand, when the vehicle is collided from the side, the operating lever 16 of the handle 1 of the broken door is
A moment of inertia in the direction in which the door lock is opened acts on the lever 21 so as to rotate the transmission lever 21 clockwise, and the transmission lever 21 is disposed eccentrically with respect to the shaft 15 and is opposite to the shaft 15 with respect to each tooth 19. Each of the mass bodies 42 disposed on the transmission lever 21 has a balanced inertia moment acting on the transmission lever 21 to balance the inertial force that causes the transmission lever 21 to move to the operation position. In particular, the moment of inertia of the balance is
The transmission lever 21 acts at least in the opposite direction to the force applied by the operation lever 16 and in the same direction as the elastic moment applied by the spring 28.
Act to keep the door substantially closed and the door closed.

When one door has a side collision,
The mass 4 of the handle 1 of the door opposite to the operation lever 16
2 do not affect the transmission lever 21. That is, the inertial force acting on the handle of the door on the opposite side maintains the operation lever 16 in the non-operation position, and rotates the member 39 clockwise in FIG.
However, as the transmission lever 21 is freely rotated in the above direction and the member 39 is rotated without exerting a moment on the transmission lever 21 in the direction in which the door lock opens, the load is simply applied to the spring 28, and as a result, the lever Numeral 21 is maintained in the non-operating position and the door is closed.

Unlike known handles, the handle 1 described herein keeps all vehicle side doors closed during a side collision, regardless of whether the side of the vehicle is the side of the collision. It is provided so that.

This is essentially because the inertial mass 42 is a transmission lever 21, in particular a one-angle locking device 57 with a stop 52 and a side surface 53.
And the mass 42 and the transmission lever 21 are angularly integrated with one another in one rotational direction about the axis 15 and in the opposite rotational direction.
Is provided by providing a mass body 42 and a transmission lever 21 that can freely rotate the lever 21 with respect to the lever 21.

[0023] Despite having an inertial mass 42 simply designed to abut the transmission lever 21, the handle 1 described here operates very quietly and is efficient. That is, the spring 28, which contacts the appendage 55 in normal operating conditions, supports the stop member 52 facing the side surface 53 over the entire operating period to somewhat prevent noise from vibration, and in particular, in the design of the bottom portion 40. This protects the hinge portion from external factors such as dust and moisture, and prevents an increase in friction at the hinge portion and, as a result, a delay in response time upon collision.

It should also be apparent that the handle 1 described and illustrated herein can be modified without exceeding the scope of the invention.

In particular, the member 39 may differ from that illustrated and may be coupled to a lock transmission lever other than the described lever.

In particular, the transmission lever 21 and the member 39 may be coupled to the structure 2 such that they rotate about two separate axes, for example, to reduce manufacturing time, and the member 39 may be a spring. The traction lever which contacts with the spring 28 and another elastic element may be gripped so that excessive compression is not applied to the spring 28.
