Description

[Detailed Description of the Invention] The present invention relates to a cab for a small truck.

A three-point seat belt is attached to a small truck, especially a small truck called a single pickup truck with a small roof area behind the seat, and the shoulder belt anchor of the belt is attached to the quarter pillar 1 as shown in Figure 1. When the quarter pillar 1 is attached to the roof panel 1, the forward load applied from the shoulder belt via the anchor 2 causes the quarter pillar 1 to tilt inward and fall forward, causing the roof panel 3 and the door opening to collapse as shown by the two-dot chain line in the same figure. It is conceivable that the pillar 1 and the door sill 4 may be deformed and disengaged from each other, and this disengagement may make the pillar 1 more likely to fall forward.

In order to prevent such deformation of the quarter pillar 1, it is possible to increase the rigidity of the entire cab by increasing the thickness of the metal plates that constitute the pillar 1, roof panel 3, back panel 5, etc. There was an inconvenience that the weight of the cab increased significantly.

This invention was made in view of the above, and
This makes it possible to effectively improve the rigidity of the quarter pillar to which the shoulder belt anchor is attached while minimizing the increase in the weight of the cab.

In order to achieve this purpose, the present invention provides a structure in which the shoulder belt anchors of the three-point seat belt are attached to the inner panel between the upper parts of the pair of left and right quarter pillars, which are supported by the inner panel. It is characterized by being connected via reinforcements extending in the left and right direction along the left and right sides.

In this way, the upper parts of the pair of left and right quarter pillars to which the shoulder belt anchors are attached are connected to each other via reinforcements that extend in the left and right direction and are arranged along the inner surface of the roof panel. In addition, the rigidity of the quarter pillar in the inward and outward directions increases significantly. Therefore, even if a large impact load is applied to the quarter pillar through the seat belt, the quarter pillar will not collapse inward and the quarter pillar will not disengage from the door sill. This increases the support strength of the seatbelt and improves the reliability of the seatbelt.

Embodiments of the present invention will be described in detail below with reference to FIGS. 2 to 4.

A back panel 13 provided with a back window and a roof panel 14 are joined and fixed to a quarter pillar 10 in which an inner panel 11 and an outer panel 12 are joined and fixed in a box-shaped cross section. It is fastened and fixed to the indoor surface of the inner panel 11 of the pillar 10 with anchor bolts 17. 18 is the door sash, 19 is the door weather strip,
20 is a roof rail, 21 is a roof lining, 22
is the back window glass, 23 is the weather strip, 24 is the quarter pillar garnish, 2
5 is a door opening trim, and 26 is an anchor plate.

Moreover, inside the rear end of the roof panel 14,
Reinforcement 2 along the inner surface of the panel 14
7 is disposed, and the upper portions of the left and right quarter pillars 10 are connected and fixed via the reinforcement 27. Then, connect both ends of the reinforcement 27 to the inner panel 1 of the quarter pillar 10.
The attachment portion of the shoulder belt anchor 16 is also reinforced by the reinforcement 27 by hanging it down along the inner surface of the shoulder belt anchor 16 to the tightening portion by the anchor bolt 17.

In the above configuration, when a load is applied from the seat belt 15 to the shoulder belt anchor 16, the quarter pillar 10 to which the anchor 16 is attached tends to tilt inward and fall forward. However, since the upper ends of the left and right quarter pillars 10 are connected via the roof panel 14 as in the conventional case, and also via the reinforcement 27 along the inner surface of the panel 14, the quarter pillars 10
The rigidity in the medial and medial directions is significantly improved. Therefore,
Even if an extremely large load is applied, the quarter pillar 10 will not incline significantly inward and the engagement between the pillar 10 and the door sash 18 will not come off, so the quarter pillar 10 is also supported by the door sash 18, and the shoulder The position of the belt anchor 16 is stabilized, and the reliability of the seat belt 15 is improved. In addition, reinforcement 27
It is needless to mention in detail that this has a sufficiently large bending rigidity.

In addition, the rear end of the cab is reinforced with left and right quarter pillars and reinforcements, so
The cab becomes more rigid, as if it were fitted with a rollover bar, which improves safety in the event of a capsize.

In the embodiment, the end of the reinforcement 27 is made to hang down to the attachment part of the shoulder belt anchor 16 to further increase the attachment strength of the anchor 16, but it is not always necessary to make the end part of the reinforcement 27 hang down to the attachment part. In other words, the specific structure of the reinforcement 27 is arbitrary as long as it connects the upper portions of the left and right quarter pillars to prevent them from collapsing inward.

As explained above, according to the present invention, the upper parts of the left and right quarter pillars to which the shoulder belt anchors of the three-point seat belt are attached are simply connected via the reinforcement along the inner surface of the roof panel, and the inner and outer parts of the quarter pillars are connected together. Since the rigidity in this direction can be significantly improved, even if a large load is applied to the shoulder belt anchor through the seat belt in the event of a collision, the quarter pillar will be less likely to fall inward, and the engagement between the pillar and door sill will be reduced. Since it becomes difficult for the pillar to come off and the amount of deformation of the pillar can be reduced, the support strength of the shoulder belt anchor is greatly improved and the reliability of the seat belt can be improved. or,
Since the reinforcement suppresses the deformation of the quarter pillars, roof panel, etc., the amount of deformation of the cab in the event of an overturn can be reduced, further improving the safety of the occupants. Furthermore, unlike in the past, there is no need to increase the thickness of quarter pillars, roof panels, back panels, etc., so the weight increase in the cab can be reduced, which in turn improves the driving performance of small trucks and reduces fuel consumption. It can also be decreased.
