Seat device for industrial vehicle

The present invention relates to a seating device for an industrial vehicle such as a forklift.

[0002] Conventionally, as shown in FIG. 14, an engine provided on a vehicle body of a forklift is covered with a bonnet 50, and a seat 51 for an operator is provided on the bonnet 50. .. Generally, the portion where the bonnet 50 is provided is formed as a driving portion, and the driving portion is provided with a handle and various operation levers. The operator performs cargo handling work by operating the steering wheel and various operating levers while sitting on the seat 51.

[0003] At this time, the operator may operate the handle or various operation levers while looking at the document 52 (for example, the warehousing / delivery slip or the like) describing the contents and procedures of the cargo handling work. In preparation for such a case, a holding tool 53 for holding the above document 52 is provided on the outer surface of the bonnet 50 on one side of the seat 51. The operator sandwiches the document 52 between the holding tools 53 and performs cargo handling work while looking at the document 52. Since the above-mentioned document 52 is sandwiched on the bonnet 50 by the holding tool 53, it is possible to prevent the document 52 from falling from the bonnet 50.

[0004] However, in the above-mentioned conventional form, since the holding tool 53 is provided on the bonnet 50, the position of the holding tool 53 is considerably larger than the position of the operator's hand sitting on the seat 51. It is separated downward. Therefore, when the document 52 is attached and detached from the holding tool 53 while sitting on the seat 51, the operator has to operate the holding tool 53 in a posture in which the upper body is bent, which causes a problem that it is difficult to work. In addition, since the distance (height difference) from the eye level of the operator sitting on the seat 51 to the holding tool 53 is long, there is a problem that it is difficult to see the document 52.

[0005] The present invention provides a seating device for an industrial vehicle in which a document can be easily attached to and detached from a document holder while sitting in a seat, and the document attached to the document holder can be easily viewed by an operator. The purpose is.
