A process for coating vegetable-tanned leathers is provided. The process includes depositing a coating layer composed of an aqueous dispersion of polyurethane resin on a support having anti-adhesion properties, curing the coating layer on the support, depositing an adhesive layer composed of an aqueous dispersion of polyurethane resin onto the cured coating layer, applying a leather piece onto the adhesive layer, the leather piece being a vegetable-tanned leather piece, in a continuous oven curing the adhesive layer to attach the leather piece to the coating layer, and removing the coated leather piece from the support. Within the continuous oven the leather piece reaches a maximum temperature comprised between 65° C. and 75° C., with a dwell time in the oven comprised between 180 and 210 seconds.

A method of manufacturing a footwear includes the steps of providing a leather base layer and providing a leather attachment layer. The leather base layer and the leather attachment layer are fixed against each other with an intermediate application of adhesive between them. The applied adhesive is activated. The leather base layer and the leather attachment layer are forced against each other under a pressure with the adhesive between them. The adhesive is cured and thereby the leather base layer and the leather attachment layer are bonded to each other. The bonded leather base layer and the leather attachment layer are integrated as part of the footwear.

The invention relates to a method for introducing weaknesses into a decorative material comprising a decorative layer and a carrier layer, preferably used for airbag coverings in motor vehicles, wherein the method comprises the following steps: a) introducing different weaknesses (21) by means of a laser (20) into sections (30) of the decorative material (10) for test purposes, wherein the different weaknesses (21) differ from one another in that the different weaknesses (21) are introduced using different parameters of the laser (20); b) measuring the tear properties of the sections (30); c) determining which section (30) which has a desired tear property and associating the relevant parameters of the laser (20) with this section (30); d) setting the laser (20) at the parameters associated in accordance with e); e) introducing weaknesses (22) into the decorative material (10) by means of the laser (20) set in accordance with step e).

A steering wheel is provided that is able to prevent damage to a layer adjacent to an outer surface layer due to an external force applied when a joined portion between outer surface layer material parts is finished.

In a steering wheel comprising a rim portion having a core metal and a covering portion 5 covering the core metal, and a mat material 6 provided between an outer surface material 9 and the covering portion 5 of the rim portion and having a conductive portion 7 on a part facing the outer surface material 9, and the outer surface material 9 has a joined portion 91 formed in a direction intersecting a circumferential direction of the rim portion, the covering portion 5 is provided with a groove 51 in which the joined portion 91 and a part of the mat material 6 are housed, and between the outer surface material 9 and the conductive portion 7, a sliding member 8 is interposed at least in a vicinity of the joined portion 91.

The example of the vehicular interior trim according to the present application is multilayer structure including at least a base material and a skin layer. The multilayer structure is configured to satisfy the relationships in the following expressions (1) and (2), where RSm (mm) is the average surface roughness of the base material in the horizontal direction, E1_80is the Young’s modulus of the base material at 80° C., d1 (mm) is the thickness of the base material, E2_80 (GPa) is the Young’s modulus of the skin layer at 80° C., and d2 (mm) is the thickness of the skin layer. Expression (1): Expression (2):

[00001]$0.15\text{<}\text{RSm}/\left(\text{E2\_80}\times \text{d2}\right)$

[00002]$\text{RSm}/\surd \left(〚\left(\text{E1\_80}\times \text{d1}\right)〛\text{^2+}〚\left(\text{E2\_80}\times \text{d2}\right)〛\text{^2}\right)\text{<135}$

There is provided a skin member having an improved appearance in a state of being attached to a base material. Skin member 12 includes a plurality of base fabrics 18, primary sewing section 20 which joins terminal portions of base fabric 18 and at least a part of which is disposed in a curved shape, secondary sewing section 22 which joins sewing region 21 of the terminal portion of each of base fabrics 18 by primary sewing section 20 to a surface of each of base fabrics 18 on a base material side, and pinking section 25 which is cut out in a zigzag shape on an end edge of sewing region 21 of base fabric 18 having a large curvature of primary sewing section 20, among the base fabrics. In pinking section 25, at least zigzag tip portions 25a and 25b are formed in an arc shape.

A fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.

A vehicle interior material in which a skin body is less likely to rise from a base material at a position of an end portion is provided. The vehicle interior material includes a base material and skin body 3 covering at least a part of a front side of the base material and bonded to the base material. Skin body 3 includes folded portion 15 folded to a side of back surface 10b. Back surface 10b is exposed to a side of the base material at a position of an end portion of folded portion 15 in an extending direction.
