The polymeric component contains a substrate (1) made of a matrix material selected from the group of polymers with a service temperature of at least 120°C, including PEEK, PEI, PI. At least portion of the surface of the substrate (1) has a surface roughness of Rz = 50 to 125 µm and is covered with a composite coating (2) having a thickness of 100 µm to 1200 µm. The composite coating (2) is applied using the electric arc spray technology (TWAS) and is composed of mixed particles of material 1 and material 2. Material 1 is selected from the group of materials including Zn, ZnAl, ZnCu, ZnMg, ZnAlMgCu. Material 2 is selected from the group of materials including stainless steel with a maximum of 15% by weight of Cr, Mg, Cu, Ni, Si, Al, Sn, CuSn, CuAl, NiAl. On the composite coating (2), there may be a protective functional layer (3) with a thickness of 100 µm to 350 µm made from material 3 - metals, alloys, or ceramics. The functional layer (3) can be applied using the methods HVOF, APS, TWAS, or CS.

The carrier comprises a back section (1) having a reverse side (back support of the bearer), provided with shoulder straps (2) and a waist belt (3), and a front side (back support of the person carried). The lower region of the front side is provided with a plate foldable relative to the back section (1), which forms a seat (4).The back section (1) may comprise two lateral vertical bars (6) connected by an upper shaft (7) and a lower shaft (8), with the seat (4) arranged on the lower shaft (8). On the sides of the carrier there may be side support mountings (5) connecting the upper region of the back section (1) and the seat (4). The support mountings (5) may be detachable from the seat (4) and foldable relative to the back section (1). Alternatively, the support mountings (5) may be flexible. The back section (1) may be disassemblable.

A sandbag includes a body (1) of elongated shape provided with a closable input opening and at least one pair of grips (3) being arranged at least on one side of the body (1), symmetrically on both sides of the transverse axis (O2).Each grip (3) includes an elongated resilient element (4) attached with both its ends to the body (1). In addition, each grip (3) includes an elongated non-deformable hollow handle (5) being provided with a sidewise open central cavity (6). The elongated element (4) extends through the central cavity (6) of the handle (5) so that the handle (5) is rotatable with respect to the elongated element (4).Some grips (3) may be directed substantially orthogonally to the transverse axis (O2) or in parallel. The sandbag may be provided with shoulder straps (7). They may contain two mutually detachable parts, where at least one part of each shoulder strap (7) has length (1) being at least double length (d) of the body (1).
