Further, multiple positioning grooves are equipped on the inside of the instrument board ontology, the slot bottom of the positioning groove is described
Flexible cloth lamella.The purpose that positioning groove is arranged is, when flexible cloth lamella and body formed instrument board sheet, flexible cloth lamella is put
Enter in instrument board forming die, setting and the matched protrusion of positioning groove on mold, protrusion jack up flexible cloth lamella, finally
After forming, flexible cloth lamella may remain in the close centre position of instrument board ontology, ensure that flexible cloth lamella and instrument
Bonding strength between plate ontology.
Further, the positioning groove is cross shape.
During fabrication, the cross section of corresponding protrusion is also cross shape, and flexible cloth lamella is in the protrusion of cross shape
Difficult to slide, molding effect is more preferable.
As described above, the integral type air bag doors of the utility model, have the advantages that：
One, process is simple, and air bag door body need not be separately configured manufacture mold in entire manufacturing process, it is only necessary at
When type instrument board, it is put into flexible cloth lamella in the mold of instrument board, greatly improves production efficiency and reduces
The cost of manufacture.
Two, in air bag explosion, the glass of automobile will not be smashed, security performance is more preferable.
