[0001] The present disclosure described herein, in general, is directed to
prevent separation of a latch cable from an insertion slot of a back door handle
5 lever of a vehicle. In particular, the present disclosure relates to a back door
handle lever of a vehicle having an improved design of the insertion slot.
BACKGROUND
[0002] The background description includes information that may be useful in
understanding the present disclosure. It is not an admission that any of the
10 information provided herein is prior art or relevant to the presently claimed
subject matter, or that any publication specifically or implicitly referenced is prior
art.
[0003] An existing type of a back door handle lever 100a of a vehicle back
door handle 100 is shown in FIG. 1A. The back door handle lever 100a comprises
15 an insertion slot 102 into which a latch cable 104 is to be fitted as shown in FIG.
1A. FIG. 1B shows a magnified view of the insertion slot 102. The insertion slot
102 is substantial of A-shape constituting two straight profiles 102a and 102c
which merge or blends with an arc-shaped profile 102b. The central axis 2-2 of
the insertion slot 102 is parallel with the longitudinal central axis 1-1 of the back
20 door handle 100 (or the vehicle’s longitudinal axis, in general). The straight
profiles 102a and 102c are tilted at an angle towards the central axis 2-2 of the
insertion slot. The angle made by each of the straight profiles 102a and 102c with
the central axis 2-2 is equal which can be perceived very well from the FIG. 1B.
The problem with the existing design of the back door handle lever 100a or
25 simply the insertion slot 102 is that the latch cable 104 often comes out or gets
separated from the insertion slot 102 due to inertia when the vehicle back door is
operated (closed) with a high force. When the latch cable 104 comes out or gets
separated from the insertion slot 102, it inhibits the functionality of the back door
3
handle 100. The current shape of the insertion slot 102 is used as the most viable
option ergonomically for the operator on an assembly line.
[0004] In view of the above-mentioned issues, there is a need to provide an
alternate or improved design of the insertion slot which can overcome the
5 shortcomings of the existing type of the insertion slot 102.
OBJECTS OF THE DISCLOSURE
[0005] Some of the objects of the present disclosure, which at least one
embodiment herein satisfy, are listed hereinbelow.
[0006] It is a general or primary object of the present disclosure to provide a
10 back door handle lever of a vehicle wherein the insertion slot is designed to
prevent the separation of a latch cable from the insertion slot on its own (e.g.
when the vehicle is moving on a bumpy road or terrain, improper insertion of the
latch cable during assembly, etc.) or on account of a high force exertion on the
vehicle back door.
15 [0007] It is another object of the present disclosure to provide a back door
handle lever of a vehicle wherein the latch cable can easily be removed or inserted
from the insertion slot by an operator if desired or required during service.
[0008] These and other objects and advantages will become more apparent
when reference is made to the following description and accompanying drawings.
20 SUMMARY
[0009] This summary is provided to introduce concepts related to a back door
handle lever of a vehicle. The concepts are further described below in the detailed

[0030] To prevent a latch cable from coming out its own of the insertion slot
15 of a back door handle lever of a vehicle, the present disclosure provides an
improved design of the back door handle lever or insertion slot. Accordingly,
FIGS. 2A and 2B show a front view of the front side and the backside,
respectively of a vehicle back door handle 200. The vehicle back door handle 200
comprises a back door handle lever 200a, a connecting portion 200b, and a main
20 housing 200c. The connecting portion 200b connects the back door handle lever
200a with the main housing 200c. The main housing 200c is connected with the
vehicle back door handle 200. The back door handle lever 200a, the connecting
portion 200b, and the main housing 200c are not exposed to the outer
surroundings of the vehicle or are hidden. The connecting portion 200b is
25 provided with a plurality of vertical ribs 200d as shown in FIG. 2B. In another
aspect, the ribs 200d can be horizontal. The ribs 200d help in providing structural
rigidity and strength to the back door handle lever 200a. The back door handle
lever 200a is made of low thickness material and is smaller in size. The back door
8
handle lever 200a comprises an insertion slot (not given reference numeral) for
receiving a latch cable.
[0031] FIG. 3A shows a magnified view of the insertion slot 300 of the back
door handle lever 200a without a latch cable inserted in it. The insertion slot 300
5 comprises a first straight profile 300a which blends or merges with an end of an
arc-shaped profile 300b, a first step-up profile 300c formed at the other end of the
arc-shaped profile 300b, and a second straight profile 300d blended or merged
with the first step-up profile 300c to form a continuous profile. The length of the
first straight profile 300a is greater than the second straight profile 300d. In an
10 aspect, the insertion slot 300 constitutes a Я-shaped profile. FIG. 3B shows a
magnified view of the insertion slot 300 of the back door handle lever 200a with a
latch cable 302 inserted in it. The central axis 2-2´ of the insertion slot 300 is at a
first predefined angle ranging from 40 to 85 degrees with respect to the vehicle’s
longitudinal axis or longitudinal central axis 1-1´ of the vehicle back door handle
15 200. In other words, the insertion slot 300 is formed tilted or at an angle to the
vehicle longitudinal axis unlike the existing type of the insertion slot 102. In an
aspect, the first predefined angle is at 70 degrees which is concluded after
optimizing both the ergonomics of the operator during assembly with respect to
fitment service hole access and the cable getting separated from the insertion slot.
20 The second straight profile 300d also forms a second predefined angle with the
central axis 2-2´ of the insertion slot 300. The first predefined angle is greater than
the second predefined angle. The first straight profile 300a helps in providing
support and guidance to an operator during fitment or insertion of the latch cable
302 in the insertion slot 300. The second straight profile 300d along with the first
25 step-up profile 300c prevents the latch cable 302 from coming out in an event of
higher force exertion on the vehicle back door handle 200. The second straight
profile 300d provides easy insertion of the latch cable 302 due to the second
predefined angle with the central axis 2-2’.
[0032] FIG. 4A and 4B show a magnified view of the front side of the back
30 door handle lever 200a. A second step profile 400 is formed at the corner edges of
9
the first straight profile 300a of the insertion slot 300 extending downwards along
an inclined portion in the connecting portion 200b. The provision of the second
step profile 400 enables the operator to remove or insert the latch cable 302 easily
without creating any hindrance thus improving serviceability of the vehicle back
5 door handle 200. The second step profile 400 is in the shape of the number “7” as
can be seen in FIG. 4B.
