Description

[0001] The present invention relates to an elastic mount for a load. The elastic mount can be used, for example, for attaching an exhaust system to a vehicle body. However, the elastic mount can also be used in other areas for supporting or securing loads to devices or assemblies. The elastic mount can be coupled to the devices or assemblies to be connected via the mount using coupling elements such as bolts or similar elements.

[0002] The suspension device disclosed in DE 100 13 121 C1, for example, is known from the prior art. The suspension device has two bushings into which bolts can be inserted. Furthermore, the receiving device comprises two joint zones, between which a load beam extends. The load beam is connected to two support legs, which in turn are connected to each other. The support legs and the load beam are made of a single piece of rubber. An insert is embedded in the support legs and the load beam. For further prior art, reference is made to documents DE 103 11 196 A1 and DE 10 2004 042 611 B3.

[0003] It is an object of the present invention to provide an elastic bearing having a predetermined rigidity and improved performance.

[0004] This object is achieved with an elastic bearing having the features of patent claim 1.

[0005] Further embodiments emerge from the dependent claims.

[0006] The elastic bearing according to the invention comprises at least one elastic body having at least two bending beams and at least two receiving openings for receiving coupling elements, wherein at least one of the at least two bending beams is connected to at least one joint section, and at least one reinforcement which is embedded in the at least one elastic body, wherein the reinforcement extends at least into the at least two bending beams, wherein the reinforcement extends at least substantially rectilinearly in the at least two bending beams in at least one predetermined section of the respective bending beam, wherein the at least two bending beams each have at least one support point which ensures the at least substantially rectilinear course of the reinforcement in the predetermined section.

[0007] The support points ensure a defined reinforcement path. This defined reinforcement path within the elastic body ensures that the elastic bearing maintains its desired stiffness. The support points prevent fluctuations in the stiffness of the elastic bearing, which can negatively impact the performance and service life of the elastic bearing.

[0008] In this context, "at least substantially rectilinear" means that the reinforcement in the predetermined section actually has a rectilinear course or, relative to a straight line extending through the receiving openings, a slight convex curvature. The straight line can run through the centers of the at least two receiving openings.

[0009] The reinforcement can extend in the at least one predetermined section of one of the at least two bending beams congruently with a straight line tangent to one of the joint sections. The reinforcement can also extend in the predetermined section at least substantially parallel to or congruent with a tangent adjacent to one of the receiving openings and to the curvature of the joint section.

[0010] The at least one support point can be provided in the region of at least one outer surface and / or at least one side surface of the elastic body. The support points can thus support the reinforcement from different directions and thus hold the reinforcement in its predetermined position.

[0011] The reinforcement sections can be fully or partially exposed at the at least one support point. In particular, the outer side of one of the reinforcement sections can be fully or partially exposed at the at least one support point. The reinforcement sections can thus be visible from the outside in the elastic body at the support points. At the at least one support point, the reinforcement section can be fully or partially free of the elastic material of the elastic body. However, it is also conceivable for a thin layer of elastic material of the elastic body to remain fully or partially retained at the support points. The material of the elastic body can be an elastomer, rubber, or even silicone. The at least one deflection point can be visible on an outer surface of the elastic body. The outer surfaces of the elastic body can, for example, have a notch at the at least one deflection point.

[0012] The elastic body has a notch or a similar feature at the at least one support point, such as a groove, a channel, or similar features. The notches at the support points can extend over the entire extent of the outer surface of the elastic body or over parts of the outer surface of the elastic body. The notch or the similar feature at the at least one support point can be formed on at least one outer surface and / or on at least one side surface of the elastic body.

[0013] The predetermined section can extend from one of the joint sections. The predetermined section can extend across the entire bending beam. The predetermined section can also extend across only one or more partial sections of the respective bending beam. The predetermined section can also extend from one of the receiving openings.

[0014] The distance between the reinforcement and the wall of an opening in the elastic body can decrease from one of the receiving openings toward one of the joint sections. The distance between the reinforcement and an outer surface of the elastic body can increase from the receiving openings toward one of the joint sections. The reinforcement cannot change its direction at the support points. The direction of the reinforcement or its angle to the straight line extending through the receiving openings remains the same at at least one support point.

[0015] The reinforcement can be supported via the support points in such a way that the reinforcement takes on an at least essentially straight course, at least in the predetermined section. During production of the elastic bearing, the reinforcement can be supported via the support points or at the support points. This can prevent the reinforcement in the area of ​​the bending beams from being pushed outwards when the elastic material for the elastic body is introduced. The support points prevent the reinforcement in the area of ​​the bending beams from taking on an undefined, curved course. The support points can ensure that the reinforcement has an at least essentially straight course, at least in the predetermined section.

[0016] The at least one reinforcement can have at least two reinforcement sections. Each reinforcement section can extend into one of the at least two bending beams. The bending beams can also each be connected to a joint section. Each of the at least two reinforcement sections can have at least one deflection point at which it changes direction. Each of the at least two reinforcement sections can be curved at the at least one deflection point in the opposite direction to its curvature in the joint section in which it extends.

[0017] Each of the at least two reinforcement sections can be concavely curved at the at least one deflection point relative to a straight line extending through the receiving openings. The straight line can, for example, extend through the centers of the at least two receiving openings. Each of the at least two reinforcement sections can be convexly curved at the at least one joint section relative to the straight line extending through the receiving openings.

[0018] The at least two reinforcement sections can be connected to one another at at least one connection point. The at least one connection point can form a deflection point in each of the at least two reinforcement sections. The at least two reinforcement sections can be sewn or woven together at the at least one connection point. At the at least one connection point, the at least two reinforcement sections can abut one another with their inner sides. The inner sides of the at least two reinforcement sections can abut one another over the entire extent of the reinforcement sections in the Y direction. The two reinforcement sections can also be connected using a distance sewing method or a distance weaving method, in which the inner sides of the reinforcement sections do not abut one another.

[0019] The elastic bearing can be constructed symmetrically with respect to a straight line extending through the at least two joint sections. The elastic bearing can also be constructed symmetrically with respect to the straight line extending through the receiving openings. The intersection of these two straight lines can define the component center of the elastic bearing. The elastic bearing can thus be constructed symmetrically with respect to both the straight line extending through the at least two joint sections and the straight line extending through the receiving openings.

[0020] The at least one deflection point can be offset from the at least one support point. The predetermined section in which the reinforcement extends at least substantially rectilinearly can extend to or near a deflection point. At the deflection point, the reinforcement changes direction significantly and then exhibits a concave curvature relative to the straight line.

[0021] Furthermore, an additional bending beam can be connected to each joint section, so that the elastic bearing can comprise four bending beams. At least one of the two receiving openings can be arranged between two interconnected bending beams. In this case, the bending beams can extend from one of the receiving openings to one of the joint sections.

[0022] The at least two bending beams and the at least two joint sections can form a spring section. At least one of the at least two receiving openings can be arranged outside the spring section. Both receiving openings can also be provided outside the spring section. The receiving opening arranged outside the spring section or the receiving openings arranged outside the spring section can lie outside the force flow of the bending beams. Furthermore, by arranging the receiving openings outside the spring section, the distance between the two receiving openings can be increased. This makes it possible to reduce the extension of the elastic bearing in the X direction. The elastic bearing can therefore take up less installation space in the X direction.

[0023] The at least one connection point at which the at least two reinforcement sections are connected to one another can be provided in the vicinity of the at least one receiving opening. Along the straight line running through the receiving openings, the at least one connection point can be provided above or below at least one of the receiving openings. The at least one connection point can also be provided between the spring section and at least one of the receiving openings. The at least two reinforcement sections can also be connected to one another at two, three, or more connection points.

[0024] A cross-sectional area of ​​at least one end of at least one of the at least two reinforcement sections can protrude entirely or partially from an outer surface of the at least one elastic body. A section of an outer surface of the elastic body can be formed by the cross-sectional area or by parts of the cross-sectional area of ​​one of the reinforcement sections. The cross-sectional areas of one end of the at least two reinforcement sections can also protrude entirely or partially from an outer surface of the elastic body or can be fully or partially visible on this outer surface. The two ends of each of the two reinforcement sections can each protrude entirely or partially from a different outer surface of the elastic body. The outer surfaces can run transversely to the straight line extending through the receiving openings.

[0025] The at least two reinforcement sections can extend independently of one another in the elastic body. The at least two reinforcement sections can form separate elements that extend separately from one another in the elastic body. The at least two reinforcement sections can have a predetermined distance from one another over their entire extent. In this case, the elastic material of the elastic body can establish a connection between the two reinforcement sections.

[0026] The at least two reinforcement sections can be formed in one piece. The at least two reinforcement sections can together form a band and each have a free end. The free ends of the two reinforcement sections can be connected to one another. In this case, the inner side of one of the two reinforcement sections can rest on the outer side of the other reinforcement section, so that the free ends are connected to one another. The free ends of the reinforcement sections can also emerge from the elastic body independently of one another at an outer surface. The two free ends of the reinforcement sections can also be connected to one another via a connection point. In this case, the two inner sides of the reinforcement sections rest against one another. The at least two reinforcement sections can also be part of an annular or circumferential reinforcement.The two reinforcement sections can also be connected using a distance sewing or weaving process, in which the two reinforcement sections are not in direct contact with each other but are connected at the joint via the existing gap. These processes can also be used to create the joints.

[0027] The elastic bearing may have a higher stiffness in the Y-axis direction than in the Z-axis direction. The at least two reinforcement sections may extend parallel to each other, at least in sections.

[0028] The at least one reinforcement is a thread reinforcement, a textile reinforcement, or a wire reinforcement. The reinforcement can be a belt, a ring, or even a film. The reinforcement can be a textile band or a textile ring. The reinforcement can be a woven band. The woven band can have gaps that allow the elastomer to flow through during injection. The reinforcement can also be a scrim of parallel individual threads. The individual threads can be connected to one another via one or more transverse threads. The reinforcement can also have cross-layers.

[0029] Exemplary embodiments of the present invention are described below with reference to the accompanying figures. They depict: Fig. 1 is a sectional view of an elastic bearing according to a first embodiment; Fig. 2 is a sectional view of an elastic bearing according to a second embodiment; Fig. 3 is a perspective view of an elastic bearing according to a third embodiment; and Fig. 4 and Fig. 5 views of further embodiments of an elastic bearing.

[0030] Fig. 1 shows a sectional view of an elastic bearing 10 according to a first embodiment. The elastic bearing 10 comprises an elastic body 12. The elastic body 12 has four bending beams 14, 16, 18, 20. The bending beams 14 and 16 are connected to one another via a joint section 22. The bending beams 18 and 20 are connected via a joint section 24. The elastic body 12 further comprises two receiving openings 26 and 28. The receiving openings 26 and 28 are designed to receive coupling elements such as bolts (not shown) that are provided on the devices to be connected via the elastic bearing 10.

[0031] A reinforcement 30 extends within the elastic body 12. The reinforcement 30 has two reinforcement sections 32 and 34. The reinforcement sections 32 and 34 extend along the bending beams 14, 16, 18, 20 and the joint sections 22 and 24. The reinforcement sections 32 and 34 run from the receiving opening 26 to the receiving opening 28. According to this embodiment, the reinforcement sections 32 and 34 are connected to one another. The reinforcement 30 can be a thread reinforcement, a textile reinforcement, or even a wire reinforcement. The reinforcement can be ring-shaped or band-shaped. A textile reinforcement can be formed by at least one textile band. The ends of such a textile band can be connected to one another. For example, the ends can be sewn or woven together. A thread reinforcement can be formed from one thread or multiple threads. The thread or threads can form a scrim or a winding.It is also possible that the threads are connected to each other.

[0032] The bending beams 14, 16, 18, 20 have support points 36, 38, 40, 42. The support points 36, 38, 40, and 42 ensure an at least substantially rectilinear course of the reinforcement sections 32, 34 in the bending beams 14, 16, 18, 20 along a predetermined section d. Over this predetermined section d, the reinforcement sections 32 and 34 can run at a substantially constant angle to the straight line G. The substantially rectilinear course of the reinforcement sections 32, 34 in section d is fixed by the elastic material of the elastic body 12. The support points 36, 38, 40, 42 are formed substantially centrally on the bending beams 14, 16, 18, 20.

[0033] At support points 36, 38, 40, and 42, notches are visible on the outer surface AF of the elastic body 12. Due to the notches, the reinforcement sections 32 and 34, or their outer sides, can be seen from the outside in the area of ​​support points 36, 38, 40, and 42. However, at notches 50, 52, and 54, a thin layer of elastic material can remain completely or partially intact over the reinforcement. The outer surface AF connects the two essentially parallel side surfaces (not shown) of the elastic body 12.

[0034] "At least substantially rectilinear" means that the reinforcement sections 32, 34 actually run rectilinearly in the predetermined section d or have a slight convex curvature relative to the straight line G. In this predetermined section d, the reinforcement sections 32 and 34 can run at a substantially constant angle to the straight line G. With the support points 36, 38, 40, 42, a defined course of the reinforcement 30 or the reinforcement sections 32 and 34 is achieved, which can ensure that the elastic bearing 10 has its desired stiffness. With the support points 36, 38, 40, 42, fluctuations in the stiffness of the elastic bearings can thus be prevented.

[0035] The elastic bearing 10 is constructed symmetrically with respect to the straight line G running through the receiving openings 26 and 28. Furthermore, the elastic bearing 10 is constructed symmetrically with respect to a straight line SG running through the joint sections 22 and 24. The intersection point of the straight line G and the straight line SG defines the center of the elastic bearing 10.

[0036] The elastic body 12 has an opening 44 with a wall W. The opening 44 extends between the receiving openings 26, 28 and the joint sections 22 and 24. Buffer elements 46 and 48 are provided in the opening 44 and extend towards one another in the opening 44. The buffer elements 46 and 48 extend in sections along the straight line G. The distance of the reinforcement 30 or the reinforcement sections 32, 34 from the wall W of an opening 44 in the elastic body 12 can decrease, starting from one of the receiving openings 26, 28 in the direction of one of the joint sections 22, 24. The distance of the reinforcement 30 or the reinforcement sections 32, 34 from an outer surface AF of the elastic body 12 can increase, starting from the receiving openings 26, 28 in the direction of one of the joint sections 22, 24.

[0037] At the joint sections 22, 24, notches 50 and 52 are visible in the elastomer body 12 on the inside of the reinforcement sections 32, 34. Notches 54 are also provided in the elastomer body 12 on the inside of the reinforcement 30 in the area of ​​the receiving openings 26 and 28. In the area of ​​the notches 50, 52, and 54, the reinforcement 30 can be fully or partially exposed. However, at the notches 50, 52, and 54, a thin layer of elastic material can also remain fully or partially over the reinforcement.

[0038] Fig. 2 shows a sectional view of a bearing 10 according to another embodiment. The bearing 10 has the elastic body 12 and the reinforcement 30. The reinforcement 30 comprises the reinforcement sections 32 and 34. The reinforcement sections 32 and 34 extend along the bending beams 14, 16, 18, 20 and along the joint sections 22 and 24. The reinforcement sections 32 and 34 are connected to one another at two connection points 56 and 58. At the connection points 56 and 58, the reinforcement sections 32 and 34 can be sewn or woven, for example. The reinforcement sections 32 and 34 can be formed, for example, by two textile bands.

[0039] In this embodiment, the bending beams 14, 16, 18, 20 also have support points 36, 38, 40, 42, which ensure an at least substantially rectilinear course of the reinforcement sections 32, 34 in the bending beams 14, 16, 18, 20 over a predetermined section d. At the support points 36, 38, 40, 42, notches are provided on the outer surfaces AF1, AF2 of the elastic body 12.

[0040] The outer surfaces AF1, AF2 connect the side surfaces (not shown) of the elastic body 12, which extend substantially parallel to one another. The outer surfaces AF1, AF2 extend between the outer surfaces 68 and 70 of the elastic body 12, which extend transversely to the straight line G. The outer surfaces 68 and 70 can extend substantially parallel to one another.

[0041] Compared with the embodiment according to Fig. 1, the predetermined section d is considerably longer according to this embodiment. Due to the support points 36, 38, 40, 42, the reinforcement 30 extends at least substantially rectilinearly to the vicinity of one of the receiving openings 26, 28. The predetermined section d spans almost the entire bending beams 14, 16, 18, 20. The support points 36, 38, 40, 42 are indicated by notches on the outer surfaces AF1 and AF2 of the elastic body 12. The notches can extend to the reinforcement 30, so that the reinforcement 30 can be fully or partially exposed at the support points 36, 38, 40, 42.

[0042] The connection points 56 and 58 lie on the straight line G above and below the receiving openings 26 and 28. At the connection points 56 and 58, each reinforcement section 32, 34 has a deflection point 60, 62, 64 and 66. At the deflection points 60, 62, 64, 66, the reinforcement sections 32 and 34 change their direction. At the deflection points 60, 62, 64 and 66, the reinforcement sections 32, 34 are curved in the opposite direction to their curvature at the joint sections 22 and 24. Relative to the straight line G, the reinforcement sections 32, 34 have a concave curvature or arch at the deflection points 60, 62, 64, 66. At the joint sections 22 and 24, the reinforcement sections 32, 34 are convexly curved or arched with respect to the straight line G. Up to the deflection points 60, 62, 64 and 66, the reinforcement sections 32 and 34 in the bending beams 14, 16, 18, 20 run at an angle to the straight line G. From the deflection points 60, 62, 64, 66 andFrom the connection points 56, 58, the reinforcement sections 32, 34 run essentially parallel to the straight line G.

[0043] The reinforcement sections 32, 34 run essentially parallel to the straight line G up to the outer surfaces 68 and 70 of the elastic body 12. The outer surfaces 68 and 70 extend essentially transversely to the straight line G and intersect it. The ends 72, 74, 76, 78 of the reinforcement sections 32, 34 can form sections of the outer surfaces 68, 70. The cross-sectional areas or even just parts of the cross-sectional areas of the ends 72, 74, 76, 78 of the reinforcement sections 32, 34 can protrude from the elastic body 12 or be visible at the outer surfaces 68, 70. The inner sides of the reinforcement sections 32, 34 abut one another at the connection points 56, 58. The inner sides of the reinforcement sections 32, 34 face each other over the entire extent of the reinforcement sections 32, 34. The outer sides of the reinforcement sections 32, 34 face away from each other over the entire extent of the reinforcement sections 32, 34.

[0044] On the joint sections 22, 24, the notches 50, 52 are formed on the inside of the reinforcement sections 32, 34. In the area of ​​the notches 50, 52, the reinforcement sections 32, 34 or their inner sides can be exposed. Unlike the embodiment according to Fig. 1, no notches are formed at the receiving openings 26, 28. The deflection points 60, 62, 64, 66 allow the distance between the receiving openings 26, 28 and the reinforcement sections 32, 34 of the reinforcement 30 to be increased. In other words, due to the deflection points 60, 62, 64, 66, more material of the elastic body 12 is present between the receiving openings 26, 28 and the reinforcement sections 32, 34. This allows for greater wear resistance of the elastic bearing 10 and lower assembly forces when attaching the elastic bearing 10 to bolts or similar coupling elements.

[0045] Fig. Figure 3 shows a perspective view of an elastic bearing 10 according to a third embodiment. The elastic bearing 10 comprises the elastic body 12. The elastic body 12 has the opening 44. The buffer elements 46 and 48 are formed in the opening 44. The notches 50 and 52 are formed on the joint sections 22 and 24 in the region of the opening 44. The bending beams 14, 16, 18, 20 extend between the receiving openings 26 and 28 and the joint sections 22 and 24. Fig. 3 also shows the X, Y, and Z axes. The definition of these axes applies to all embodiments described here.

[0046] The outer surfaces AF1 and AF2 of the elastic body 12 connect the outer surfaces 68, 70. The outer surfaces AF1 and AF2 connect the essentially parallel side surfaces SF of the elastic body 12, of which Fig. 3 only one is shown. The support points 36, 38, 40, 42 can be seen on the outer surfaces AF1, AF2 of the elastic body 12, which run along the bending beams 14, 16, 18, 20. The support points 36, 38, 40, 42 are indicated by the notches on the outer surfaces AF1, AF2 of the elastic body 12. The outer surfaces AF1 and AF2 have a predetermined extension in the Y direction. The support points 36, 38, 40, 42 and the notches at the support points 36, 38, 40, 42 extend substantially in the Y direction. The support points 36, 38, 40, 42 can extend over the entire outer surfaces AF1, AF2 or only over parts of the outer surfaces AF1, AF2.

[0047] It is further possible for at least one support point SST to extend on the side surface SF of the elastic body 12, which holds the reinforcement 30 or the reinforcement sections 32 and 34 in position in the Y direction.

[0048] Fig. Figure 4 shows a view of an elastic bearing 10 according to another embodiment. The elastic bearing 10 comprises the elastic body 12. The elastic body 12 has four bending beams 14, 16, 18, 20. The bending beams 14 and 16 are connected to one another via the joint sections 22 and 24. The elastic body 12 further comprises the two receiving openings 26 and 28. The basic structure of the elastic bearing 10 according to Fig. 8 corresponds to the structure of the Fig. 1 described embodiment.

[0049] The reinforcement 30 extends within the elastic body 12. The reinforcement 30 has two reinforcement sections 32 and 34. The reinforcement sections 32 and 34 extend along the bending beams 14, 16, 18, 20 and the joint sections 22 and 24. According to this embodiment, the reinforcement sections 32 and 34 are connected to one another, so that the reinforcement 30 also extends along the receiving openings 26 and 28.

[0050] The reinforcement sections 32 and 34 extend from the joint sections 22 and 24 in a predetermined section d essentially straight into the bending beams 14, 16, 18, 20 in the direction of one of the receiving openings 26, 28. In the predetermined section d, the reinforcement sections 32, 34 run essentially along an imaginary straight line or have a slight convex curvature relative to the straight line G. This essentially straight course can be produced with support points 36, 38, 40, 42. Notches in the elastic body 12 can be seen at the support points 36, 38, 40, 42. During the manufacture of the elastic bearing 10, the reinforcement sections 32 and 34 are supported at the support points 36, 38, 40 and 42 in order to ensure the substantially rectilinear course of the reinforcement sections 32 at least over the predetermined section d.The essentially straight course of the reinforcement sections 32, 34 in section d is fixed by the elastic material of the elastic body 12.

[0051] Furthermore, two deflection points 80, 82, 84, 86 are provided in the reinforcement sections 32 and 34. At the deflection points 80, 82, 84, 86, the reinforcement sections 32 and 34 change their direction. Due to the deflection points 80, 82, 84, 86, the reinforcement sections 32, 34 have a substantially concave curvature relative to a straight line G running through the receiving openings 26 and 28. Thus, the reinforcement sections 32, 34 initially extend at least substantially rectilinearly from the joint sections 22 and 24 due to the support points 36, 38, 40, 42 until they change their direction at the deflection points 80, 82, 84, 86. At the deflection points 80, 82, 84, 86, the reinforcement sections 32, 34 transition into a concavely curved shape. The support points 36, 38, 40, 42 are located closer to the joint sections 22, 24 than the deflection points 80, 82, 84, 86.The support points 36, 38, 40, 42 thus ensure an at least substantially rectilinear course of the reinforcement sections 32, 34 in section d. The reinforcement sections 32, 34 therefore do not change their direction at the support points 36, 38, 40, 42, whereas the reinforcement sections 32, 34 change their direction at the deflection points 80, 82, 84, 86. Due to the support points 36, 38, 40, 42, the reinforcement sections 32, 34 assume a predefined course in the elastic body 12. The support points 36, 38, 40, 42 contribute to adjusting the stiffness of the elastic mount 10.

[0052] Fig. Figure 5 shows a sectional view of an elastic bearing 10 according to another embodiment. The bearing 10 comprises the elastic body 12 and the reinforcement 30. The reinforcement 30 comprises the reinforcement sections 32 and 34. The reinforcement sections 32 and 34 extend along the bending beams 14, 16, 18, 20 and along the joint sections 22 and 24. The reinforcement sections 32 and 34 are connected to one another at the connection points 56 and 58.

[0053] In this embodiment, the bending beams 14, 16, 18, 20 also have the support point 36, 38, 40, 42.

[0054] In the embodiment according to Fig. 5, the deflection points 80, 82, 84, and 86 are arranged closer to the deflection points 60, 62, 64, and 66, which are formed by the connecting points 56 and 58. Due to the closely arranged deflection points 80, 82, 84, and 86 and 60, 62, 64, and 66, the direction of the reinforcement sections 30, 32 is changed twice at a short distance. The basic structure of the elastic bearing 10 according to Fig. 5 corresponds to the structure of the Fig. 2 described embodiment.

[0055] The support points 36, 38, 40, 42, SST can be used to create a defined course of the reinforcement sections 32, 34 in the elastic body 12, whereby the rigidity of the elastic bearing 10 can be precisely adjusted. During the manufacture of the elastic bearing 10, the reinforcement sections 32 and 34 are supported at the support points 36, 38, 40, 42, SST in order to ensure the at least substantially rectilinear course of the reinforcement sections 32, 34 at least over the predetermined section d. The support of the reinforcement sections 32 and 34 prevents the elastic material of the elastic body 12 from pressing the reinforcement sections 32 and 34 outwards during manufacture. By supporting the reinforcement sections 32 and 34 at the support points 36, 38, 40, 42 during the manufacture of the bearing 10, it is thus possible to prevent the reinforcement sections 32 and 34 from taking on an undefined arcuate course.The at least substantially straight course of the reinforcement sections 32, 34 in section d or in the bending beams 14, 16, 18, 20 ensures that the elastic bearing 10 has its desired stiffness. Thus, fluctuations in the stiffness of the elastic bearing 10 can be prevented.

[0056] During the manufacture of the elastic bearing 10, the reinforcement sections 32, 34 can be supported by a support tool, multiple support tools, or support elements. The aforementioned tools or elements can be introduced into a cavity of an injection mold to support the reinforcement 30. The support can occur, in particular, during the injection of the elastic material for the elastic body 12. The support tools or support elements ensure that the reinforcement sections 32, 34 have their predetermined course, which is then fixed by the elastic material of the elastic body 12. The notches or similar features at the support points 36, 38, 40, 42 in the elastic body 12 can correspond to the points of application of the support tools or support elements. The support tools or support elements can engage the reinforcement 30 at these points of application to support the latter.
