Description

  The present invention relates to an instrument panel module mounted on a vehicle.

  In general, a vehicle air conditioner is housed inside an instrument panel disposed in a front part of a passenger compartment of an automobile. In recent years, an instrument panel module has been configured by integrating these instrument panels and air conditioners before they are mounted on a vehicle (see, for example, Patent Document 1). By configuring this instrument panel module, it is possible to reduce the number of parts that require assembly work on the vehicle in the vehicle production line, and to reduce the number of steps in the vehicle production line.

In addition, although the shape of the instrument panel is different for models with a common body structure, the air conditioners can often be used in common. Attempts have been made to reduce administrative costs.
JP-A-2005-175852

  However, in the conventional instrument panel module, the presence or absence of so-called rear heat that blows conditioned air to the rear seat side is determined according to the size and specifications of the interior space of the vehicle. In this case, depending on the presence or absence of rear heat, it is necessary to manufacture two types of air conditioners: an air conditioner having a rear seat foot outlet and an air conditioner not having a rear seat foot outlet. There was a problem that the product management cost increased.

  The present invention has been made in view of such a point, and an object of the present invention is to easily change the specification as to whether or not to send conditioned air to the rear seat side without changing the shape of the vehicle air conditioner. It is to provide an instrument panel module that can.

  In order to achieve the above-described object, the present invention can set whether or not to block the rear seat foot outlet of the vehicle air conditioner by a closing member that is detachably attached to the instrument panel side.

  Specifically, the present invention is directed to an instrument panel module including an instrument panel disposed in a passenger compartment and a vehicle air conditioner housed in the instrument panel. Measures were taken.

That is, according to the invention of claim 1, a rear seat foot outlet for blowing conditioned air to the rear seat side is formed in the vehicle air conditioner.
The instrument panel is detachably attached with a closing member that closes the rear seat foot outlet,
The closing member is arranged so as to close the rear seat foot outlet when the vehicle air conditioner is positioned at a storage location in the instrument panel.

The invention of claim 2 is the invention according to claim 1,
The instrument panel includes a cross member extending in the vehicle width direction, and two reinforcing members that are spaced apart from each other in the vicinity of the center position of the cross member in the vehicle width direction and extend obliquely downward toward the rear of the vehicle body. With
The blocking member is attached across the two reinforcing members.

The invention of claim 3 is the invention according to claim 1 or 2,
The closing member is provided with a sealing material corresponding to the opening peripheral edge of the rear air outlet for the vehicular air conditioner.

  According to the first aspect of the present invention, the closing member detachably attached to the instrument panel closes the rear seat foot outlet when the vehicular air conditioner is positioned at the accommodation location in the instrument panel. Therefore, the rear seat foot outlet can be closed at the time of assembling work for assembling the instrument panel module by attaching the vehicle air conditioner to the instrument panel. In other words, regardless of the presence or absence of the rear heat specification, a rear seat foot outlet is formed in the vehicle air conditioner, and a blocking member is provided on the instrument panel side whose shape is changed according to the presence or absence of the rear heat specification. If it is determined whether or not to be attached, it is possible to easily change the specification of the rear heat without increasing the number of types of vehicle air conditioners, which is advantageous in reducing manufacturing costs and product management costs.

  In addition, it is conceivable that a closing member is directly attached to the rear air outlet for the vehicle air conditioner. In this case, the operator appropriately determines the rear heat specifications when assembling the instrument panel module. However, if the closing member is attached to the instrument panel side as in the present invention, the operator must check whether the rear heat specification is present or not. It is only necessary to repeat assembly work without making a decision, and work efficiency is improved.

  According to the invention which concerns on Claim 2, since it was made to attach a closure member straddling the two reinforcement members which comprise an instrument panel, when positioning a vehicle air conditioner in the accommodation location of an instrument panel, The rear seat foot outlet can be reliably closed with the closing member. That is, since the closing member is firmly fixed to the reinforcing member, when the rear seat foot outlet is abutted against the closing member vigorously, the closing member is displaced due to the impact and the sealing performance is deteriorated. This is preferable because it is possible to prevent the occurrence of defects.

  According to the invention of claim 3, since the sealing member is provided on the closing member corresponding to the opening peripheral edge of the rear seat foot outlet of the vehicle air conditioner, the vehicle air conditioner is connected to the instrument panel. When positioned at the housing location, the rear seat foot outlet can be more reliably closed while improving the sealing performance with the sealing member of the closing member.
